1.0 INTRODUCTION
This operations manual is
applicable to instruments with
serial numbers of 2000001F and
greater. If you require an
operations manual for an
instrument with an earlier serial
number, please contact NAG
Marine for assistance.
1.1 General
This manual contains instructions for the
installation, operation and maintenance of
the TD-1075.0 OCM. For information
regarding the installation, operation and
maintenance of associated equipment
supplied by NAG Marine, refer to the
separate manual supplied with those
products.
Improper installation, use,
application or unauthorized
servicing of this equipment
voids all warranties.
The TD-1075.0 must be installed,
operated, and maintained
according to this manual to
remain in compliance with DNV TAP NO.
771.61 regulations. Operation of the TD-
1075.0 OCM in a manner other than
described here may be documented by
the instrument and may result in the
invalidation of the DNV TAP NO. 771.61
Certification. Failure to adhere to the
directions and recommendations exactly
as presented in this manual may result in
oil discharges violating DNV TAP NO.
771.61 regulations.
The TD-1075.0 Oil Content Monitor (OCM) is
a DNV TAP NO. 771.61 certified 5 ppm
Bilge Alarm. Its primary function is to
monitor bilge water oil content and facilitate
the activation of discharge control devices
to divert bilge water discharge in the event
oil content exceeds 5 ppm. The TD-1075.0
OCM also permits process monitoring
through system-function relays, oil content
relays, and analog sample concentration
outputs. Compared with oil content
detection technologies that utilize turbidity
or light scatter techniques, the TD-1075.0
OCM offers:
•Resistance to high oil content readings
resulting from suspended non-oil
particles.
•Selectively tuned optics to minimize
chemical interferences.
1.2 Symbols
The following symbols are used to call
attention to specific types of information.
A warning to use caution! In
some instances, personal injury
or damage to the TD-1075.0 OCM
may result if these instructions are not
followed properly.
An explanation or information of
interest.
If the manual instructs the user to press a
key on the instrument, the designated key
will be CAPITALIZED in boldface type
enclosed by < >.
Display screen names will be in boldface
type and in ALL CAPITALS.
References to appendixes, tables and
figures will be in boldface type and in
italics.
2.0 THEORY OF OPERATION
The TD-1075.0 OCM measures the oil
content of post oily water separator (OWS)
effluent via fluorescence. Fluorescence
occurs when a molecule—in this case a
hydrocarbon molecule—relaxes to its
ground state after being electronically
excited. Fluorescent hydrocarbons absorb
light—excite— at one wavelength and emit
light—relax— at a longer (less energetic)
wavelength. The emitted light is filtered and

TD-1075.0 Oil Content Monitor
Operation Manual
6
translated to a voltage response which
corresponds to the concentration of
fluorescent hydrocarbons in the sample.
The TD-1075.0 OCM contains five important
components that it uses to make the
fluorescence measurement:
1. Light Source
2. Excitation Filter
3. Sample Cell
4. Emission Filter
5. Light Detector
2.1 Light Source
The TD-1075.0 OCM light source emits
photons over a specific wavelength range.
The light source wavelength range has
been selected to maximize the response of
the targeted oil and meet the DNV TAP NO.
771.61 mandated detection range while
minimizing the impact of chemical
interferences and sample turbidity. The light
source also has an internal power output
monitor to determine light output
independent of the fluorescence
measurement.
2.2 Excitation Filter
The excitation filter narrows the range of
wavelengths emitted by the light source.
The excitation filter is also selected to
maximize the response of the targeted oil
and meet the DNV TAP NO. 771.61
mandated detection range while minimizing
the impact of chemical interferences and
sample turbidity.
2.3 Sample Cell
The sample cell is the portion of the sample
block where the water sample is exposed to
the light transmitted by the excitation filter.
2.4 Emission Filter
The light emitted by the sample passes
through an emission filter, which narrows
the range of wavelengths once again. This
ensures only the desired wavelengths—
those emitted by the targeted oil— are
transmitted to the light detector. The
emission filter is selected to maximize
transmission of light emitted by the targeted
oil while meeting DNV TAP NO. 771.61
performance criteria.
2.5 Light Detector
The light detector produces a pulse of
electricity when it detects a photon that has
passed through the emission filter. The TD-
1075.0 OCM counts these pulses and relates
that value to the stored calibration value to
determine the oil content of the water
passing through the sample cell.
2.6 Control Functions
The TD-1075.0 is a microprocessor-based
instrument designed to measure the oil
content in the sample, display the current oil
content, and report the value to the
Datalogger. The digital display shows the oil
content (0.000–999 ppm), any internal
alarm notification, process water temp and
the cell condition %. Additional information
is displayed or changed by pressing various
keys on the instrument keypad. Additional
diagnostic information is also recorded in
the Datalogger. The TD-1075.0 OCM
provides the following control functions:
1. Activates the High (5 ppm) Signal Alarm
upon the concentration reaching 5.0
ppm.
2. Activates the Early Warning upon the
concentration reaching 3.0 ppm (the
default value) or any user defined set
point between 1.0 and 3.0.
3. Activates the Zero Signal Alarm when
the concentration is measured at
approximately 0.0 ppm.
4. Activates a System Alarm when there is
an OCM failure. Also activates a High
Signal Alarm and Cell Alarm.
5. Activates High Signal Alarm, Early
Warning, Zero Signal Alarm, and
System Alarm Relays when the TD-
1075.0 OCM is put into the
MAINTENANCE MODE.
6. Activates the Cell Condition Alarm when
below the minimum voltage limit for light
transmitted through the sample cell. In
addition to the Cell Condition Alarm, a
High Alarm and a System alarm will also
be activated in this case.

4.0 INSTALLATION
4.1 Pre-Installation/Installation
Do not break the provided
tamper evident DNV certification
seal for any reason. Breaking
such seals will invalidate the DNV
certification of the monitor.
The Pre-Installation/Installation Checklist
found in Appendix A provides important
guidelines and information to aid in
preparing for installation.
4.2 Required Tools & Accessories
•Standard plumbing and electrical tools
are required for installation.
•NAG Marine recommends that stainless
steel flexible tubing be used on the inlet
and outlet connections. This will
facilitate future maintenance and
prevent damage to the monitor from to
transmitted vibration and/or pipe strain.
•DNV Certified OWS system including
diverter valve.
4.3 Location & Sampling Point
The sampling point should be located such
that the sample is homogeneous and free of
all air. It should also approximate the bulk
oil concentrations of the treated bilge water.
It is extremely important to eliminate air
entrapment in the sample line. The best way
to accomplish this is to sample from the
center of the pipe or from the side of the
pipe.

The unit should not be installed:
•Adjacent to known heat sources or in
direct sunlight; this could cause the
internal temperature of the unit to be
significantly higher than ambient
temperature and produce errors or
damage the components.
•Within 10 feet [3.05 m] of devices such
as large generators or transformers,
which generate a strong electromagnetic
field—cooling water recirculating pumps
are not a problem.
The maximum environment
temperature is specified at 120 °F
[49 °C].
4.4 Mechanical Connections
Refer to the General Arrangement
Drawings for the location of the required
mechanical connections. The TD-1075.0
OCM must be mounted to a vertical surface
with the mounting tabs. The mounting tabs
accept a maximum 0.375 in. [9.53 mm]
diameter bolt.
Two 0.25 in. [6.35 mm] connections are
provided for pipe hook-up.
•Sample inlet line: 0.25 in. [6.35 mm]
FNPT. An inlet relief valve may be
added on systems where the possibility
of over pressurization exists. See
General Arrangement Drawings for
recommended installation method.
•Sample outlet line: 0.25 in. [6.35 mm]
compression tube fitting. Spacer PN
105978 is used to prevent inadvertent
over-tightening of the NPT fitting. Over
torqueing may cause movement or
damage to the internal components of
the sample block, specifically the
internal threads, quartz flow cell, and
flow cell O-ring. The NPT fitting
maximum torque is 30 in-Ibs.
•Optional vent connection: 0.25 in. [6.35
mm] compression tube fitting. See
General Arrangement Drawings.
The outlet plumbing connections
MUST NOT place stress on the
0.25 in. [6.35 mm] tube drain
connection point. Damage to the
instrument may occur if plumbed
incorrectly.
Pipe rises greater than 10 ft [3.05 m]
should be avoided. In installations
where this is not feasible, contact
NAG Marine for assistance.
Mounting the unit at eye level is
recommended.
4.4.1 Flow Rates and Tubing
Sample Flow Rates:
•0.13 U.S. gal/min [0.5 L/min] minimum
•U.S. gal/min (3.78L/min) maximum
Sample Pressure:
•Less than [689.5 kPa(g)] 100 psig
Greater than 1 psig
Recommended Maximum Sample
Tubing
Dimensions:
•Diameter: 0.25 in. [6.35 mm]
•Length: 25 ft [7.62 m]
Higher flow rates may require more
frequent cleaning of the sample cell.
4.4.2 Drain/Outlet
Sample outlet from the TD-1075.0 OCM
should be piped to either an atmospheric
drain with no back pressure or a
pressurized system. Atmospheric drains
must have the drain pipes terminate below
the unit. Pressurized system discharge must
create sufficient pressure drops to create
flow through the instrument. Do not combine
the discharge from other devices to the TD-
1075.0 OCM discharge.
In installations where this is not
feasible, contact NAG Marine for
assistance.

4.5 Power and Input/Output Signal
Requirements
4.5.1 Power
Required Power: 20-240 VAC, 50/60 Hz,
15 W or 20-240 VDC. Power must be
connected to the monitor at all times.
4.5.2 Input Signals
The TD-1075.0 OCM requires two input
signals for operation. They are the Oily
Water Separator (OWS) Status signal and
the Flow Status signal. These signals
communicate to the TD-1075.0 OCM that
there is an operational OWS connected and
the status of its function. The following input
signal is required for both the Separator
Status and Flow Status signals.
•Input Required: Continuity or a 3–28
VDC, min 10 mA, max 100 mA signal.
If the Separator Status input signal
is not present, the monitor will send
an alarm signal to close the
overboard discharge valve. This alarm
signal functions in the same manner as the
High (5 ppm) Alarm signal.
4.5.3 Output Signal Relays
There are five output signal relays providing
information on the sample and the system
status of the TD-1075.0 OCM. They are as
follows: High (5 ppm) Signal Alarm, Early
Warning, Zero Signal Alarm, System Alarm
and Cell Condition Alarm. The relay
specifications are:
•Relay Type: Normally Open
(NO)/Normally Closed(NC) dry contact
•Relay contact rating: 240 VAC or 28
VDC, 6 A.
The High (5 ppm) Signal Alarm
relay output must be connected
to the vessel’s diverter valve (or
to the system that controls the valve) in
order for it to actuate the valve. If the
High (5 ppm) Signal Alarm relay is not
properly connected, the instrument will
still indicate an alarm condition but
overboard discharge will not cease.
4.5.4 Signal Output
One internally-powered 4–20 mA signal
(isolated) providing a 0.0–30.0 ppm
measurement range.
4.5.5 USB
The USB port is located internally on the
Datalogger PCB. It must remain accessible
for data retrieval. Only USB sticks which do
not have internal compression programs will
function correctly, these are available
through NAG Marine or TDHI.
4.6 Electrical Connections
Only trained personnel should
make electrical connections.
Refer to the General Arrangement
Drawings for the input and output terminal
locations required for the power, alarm
outputs, process status inputs, and 4–20
mA connections.
Do not break the provided tamper
evident DNV certification seals for
any reason. Breaking such seals will
invalidate the DNV certification of the
monitor.
The 4–20 mA output is internally
powered and internally shielded. DO
NOT connect customer end of shield
to ground.
4.6.1. Making Wiring Connections
To connect a wire to the pre-wired cabling:
1. Turn off main power to the instrument at
the breaker.
2. Verify all process inputs and switched
outputs are off.
3. Terminate the wire cabling as mandated
by shipboard requirements in junction

procedure.
5.4 Shut-Down Sample Cell
Maintenance and Cleaning
After Completing OWS operations:
It is important to fill the TD-107
Sample Cell with fresh clean water at
the end of every OWS operation. A cell
which is left filled with either dry air or dirty
sample water can permanently foul the
sample cell. Fill the sample cell with clean
water at the end of OWS operations in order
to maintain proper operation of the unit.
1. Close the TD-107 inlet valve handle.
MAINT MODE will be displayed on the
left side of the LCD.
2. Use the supplied syringe to inject 60 mL
of fresh clean water into the sample cell
via the Luer-Lok® fitting. Leave the TD-
107 inlet valve handle closed while the
OWS is secured.
6.0 CALIBRATION CHECK
6.1 Calibration Check Procedure
Refer to Appendix K: General
Arrangement Drawings for locations of
items. A diagram of display screens is
located in Appendix E.
Perform the following steps to check the
fluorescence calibration:
1. Close the inlet valve. The instrument will
now be in Maintenance Mode. A
Maintenance event will be recorded by
the Datalogger. Confirm

TD-1075.0 Oil Content Monitor

discharge/outlet piping is not
pressurized.
2. Clean the unit by injecting 60 mL of
cleaning solution into the sample cell
with one of the provided 60 mL syringes.
The syringe screws onto the Luer-Lok®
connector on the inlet valve. Inject the
cleaning solution at a slow, steady rate
into the sample cell. Allow the cleaning
solution to remain in the sample cell for
three to five minutes. Then, using a
clean 60 mL syringe, flush sample cell
thoroughly with 120 mL of DI water.
A syringe is provided in the 2-Year
Spares Kit (P/N NAG2520).
3. Using the same DI water
syringe, inject another 60 mL of DI water
into the sample cell and allow it to
remain in the sample cell by leaving the
syringe attached. Note the HOME
screen reading for the clean water. It
should read 0 ± 2 ppm.
4. Using another clean syringe, inject 60
mL of check solution and allow it to
remain in the sample cell by leaving the
syringe attached. Note the HOME
screen reading. It should be within ± 2
ppm of the value on the bottle. If not,
clean the sample cell and repeat steps 1
through 4.
5. Remove the syringe. Open the inlet
valve to allow normal operation of the
instrument. The instrument will no
longer be in Maintenance Mode.
Bubbles trapped during injection
are a possible source of instrument
error. With the syringe in a vertical
position, tap against a solid object to move
bubbles to the needle end of the syringe.
Then, force bubbles out by pushing a small
amount of solution through the needle end
of the syringe.
7.0 TD-1075.0 OCM SOFTWARE
FUNCTIONS
The TD-1075.0 OCM has menu driven
software that simplifies the user interface.
The following descriptions of the user
interface functions will help provide a better
understanding of the interface. See
Appendix E for a visual depiction of the
listed functions.
7.1 Screens
A series of computerized screens built into
the unit are accessed using the keypad and
shown on the LCD.
7.1.1 HOME Screen
The HOME screen is displayed
continuously during normal operation. The
current oil concentration reading (in ppm) is
obtained from this screen. The presence of
an alarm is also indicated on the HOME
screen by ‘ALM’ flashing in the upper left-
hand corner. Other screens are accessed
from the HOME screen by pressing various
keys on the keypad.
7.1.2 Warning Screens
There are warning screens throughout the
software, which inform of invalid entries (for
values or ID).
7.1.3 Alarms
When an alarm occurs, "ALM" blinks in the
upper left-hand corner of the HOME screen.
The nature of the alarm can be determined
by pressing <ESC> from the HOME screen.
The alarm history can be viewed from the
HOME screen by pressing <>.
7.1.4 Parameter Screens
These screens are accessed by the various
numerical keys. Most of these screens are
view-only and require a service ID to
change the values.
7.1.5 Diagnostics Screens

14
different measurements taken by the OCM
sensors.
7.1.6 Cell Condition and Zero Drift
Correction
The cell condition and zero drift correction is
electronic and self-correcting.
7.2 Keypad Functions
7.2.1 Left Arrow
The left arrow is used to correct typing
errors when data is being entered or
changed (as a backspace or delete key). It
is also used from the HOME screen to view
the alarm history and to move backwards
through the diagnostics screens.
7.2.2 Up & Down Arrows
From HOME screen, these arrows can be
used to adjust the LCD contrast.
7.2.3 Enter Key <ENT>
The <ENT> key is used to accept values,
access parameter change screens, access
the CAL DATA screen and move forward
through the diagnostics screens.
7.2.4 Escape Key <ESC>
The <ESC> key is used from the HOME
screen to view the current alarms. <ESC> is
also used to return to a previous screen or
to exit a parameter change screen after the
parameter has been changed.
7.2.5 Home Key <HOME>
The <HOME> key will return the user to the
home screen from any of the various
parameter screens.

7.3 Standby Mode
The TD-1075.0 is equipped with a standby
mode to preserve the operating lifetime of
the detection system. There are two preset
standby delay times; 10 minutes and 30
minutes.
7.3.1 10 Minute Delay
The 10 minute delay is operational in the
normal instrument operating mode. The
trigger for the initiation of the 10 minute
delay countdown is the SEPARATOR
alarm. If after the alarm is triggered 10
minutes elapse with no record of a key
pressed, the detection system will turn off
and the LCD will display a STANDBY
message. From the STANDBY screen, the
press of any key will restart the detection
system and the 10 minute delay clock. From
there, the 10 minute delay is restarted after
each press of a key. If while the TD-1075.0 is
in standby the OWS is started, the detection
system will turn on and oil in water
measurements will resume
7.3.2 30 Minute Delay
The 30 minute delay is operational only
when the inlet valve handle is closed
(MAINTENANCE MODE). The movement of
the handle from open to closed is the trigger
to start the 30 minute countdown. If no keys
are pressed for 30 minutes after the valve is
closed, the detection system will turn off and
the LCD will display a STANDBY message.
From minute 30 to minute 11 in the
countdown, pressing a key will do nothing to
reset the countdown timer. With less than
10 minutes remaining in the countdown, any
key pressed will restart the countdown timer
at 10 minutes. The only mechanism
available to restart the 30 minute delay
clock is to open and then close the
instrument inlet valve. If the instrument is
experiencing a SEPARATOR alarm and
already in the 10 minute countdown
window, moving the inlet valve handle to
close will still initiate the 30 minute
countdown.
8.0. DATALOGGER
8.1. General
The Datalogger maintains alarm events and
concentration readings for a minimum of 18
months. Although the data can be retrieved
at any time, data cannot be deleted or
edited from the memory of the TD-1075.0
OCM. Data are retrieved by inserting a USB
data key into the USB data port. The
“EVENTS.txt” and “ALLDATA.txt” files which
are transferred to the USB data key can
then be reviewed via computer. Data
exceeding the large storage capacity (more
than 18 months) will be overwritten on a first
in-first overwrite basis. All dates and times




TD-1075.0 Oil Content Monitor

are set to Greenwich Mean Time (GMT) and
cannot be changed.
The following alarms and indications are
possible logged events within the
Datalogger:
•POWER ON: Indicates that the power
has been turned on.
•FLOW: Indicates whether the bilge
water is flowing to the monitor. Unless a
meter or external sensor input is
supplied, the flow input signal is derived
from auxiliary contacts on the separator
pump. Closed contacts on the pump
contact or provide the input signal to the
OCM flow contacts TB1 & 2 on the OCM
relay board.
•SEPARATOR: Indicates whether the
separator is operating. This signal is
derived from the pump contactor
however the input to the separator
signal on the datalogger may be derived
from auxiliary contacts on the OWS
main power contactor. Closed contacts
indicate separator on.
•HIGH (5 ppm) SIGNAL ALARM:
Indicates that the oil content is 5.0 ppm
or higher.
•EARLY WARNING: Indicates that the
oil content is higher than the set point
stored in the instrument.
•ZERO SIGNAL ALARM: Indicates that
the oil content reads 0.0 ppm. This
signal is logged for information purposes
and has no effect on OCM operation.
•CELL CONDITION: Indicates the
sample cell has reached oil detection
limit of 10% and the cell could require
cleaning.
•MAINTENANCE MODE: Indicates that
the monitor is being maintained (or that
the inlet valve is closed). Note that all
alarm relays are in alarm state while in
Maintenance Mode.
•INSTRUMENT ALARM: A datalogger
event that can be caused by one of the
following alarms: LED Failure, Cell
Condition, or High Water Temperature.
8.2 Data Retrieval
Perform the following steps to retrieve data
from the Datalogger:
1. Close the inlet valve. This will log a
MAINTENANCE MODE event.
2. Open the enclosure door and insert a
USB data key into the USB data
port.“EVENTS DOWNLOAD“ will flash
on the LCD to indicate that the
“EVENTS.txt” file is being written to the
USB key. A row of ‘’ will appear
across the bottom of the LCD as the file
writing progresses. This process may
take some time if the file to be written is
large.
3. “ALLDATA DOWNLOAD“ will flash on
the LCD to indicate that the
“ALLDATA.txt” file is being written to the
USB key. A row of ‘’ will appear
across the bottom of the LCD as the file
writing progresses. This process may
take longer than Step 4 due to the larger
file size.
4. When the LED is not illuminated the
USB key can be safely removed.
5. Shut and secure the enclosure door
after retrieving data.
The data files are text files that can be
imported into a computer. The EVENTS.txt
file only writes when there is a change of
alarm states. It includes the time and date
upon which alarm event occurred in addition
to the concentration measurement at that
time. The ALLDATA.txt file writes every 10
seconds with all alarm events and
concentration measurements.
Failure to shut the enclosure door
properly can result in corrosion of
the internal electronics.

TD-1075.0 Oil Content Monitor
Operation Manual
17
The “EVENTS.txt” data file is
written first, followed by the
“ALLDATA.txt” data file. A 512 MB
minimum size data key for file retrieval is
recommended.
Any existing Datalogger
(EVENTS.txt or ALLDATA.txt) files
on the USB data key will be
overwritten during the data retrieval
process. Electronic files generated by other
programs will not be erased from the USB
data key or overwritten during the data
retrieval.

9.0. TD-1075.0 OCM
MAINTENANCE
Do not break the provided tamper
evident DNV certification seals for
any reason. Breaking such seals will
invalidate the DNV certification of the
monitor.
When performing maintenance,
always move the inlet valve to the
maintenance position.
Improper installation, use,
application or unauthorized
servicing of this equipment voids all
warranties.
Proper maintenance and cleaning of
the TD-107 sample cell is a key
component of consistent oil content
monitoring. Significant build-up of residue,
iron oxide, or other foreign material on the
inner quartz tube can materially affect the
measurement of the fluorescent properties
of the oil. Consistently following these
simple cleaning and maintenance
procedures will ensure accurate and reliable
operation from the monitor.
9.1 Battery Back-Up
TD-1075.0 OCM System Values are retained
in battery back-up memories for up to five
years. However, the Start-Up procedure
should be followed to ensure oil content
monitor calibration and control settings are
correct if the unit has been disconnected for
any length of time. The battery is not user-
serviceable. The back-up battery should be
replaced during re-calibration of the TD-
1075.0 OCM by a factory-authorized dealer.
The Datalogger data are retained in battery
back-up memories for up to seven years.
The battery is not user-serviceable. The
back-up battery should be replaced during
re-calibration of the TD-1075.0 OCM by a
factory-authorized dealer.
9.2 Preventative Maintenance
Preventative maintenance should be
performed to ensure optimum monitor
operation and maximum life. The two
maintenance actions that the user can
perform are Sample Cell Cleaning and
Desiccant Plug Replacement.
9.2.1 Desiccant Plug
The TD-1075.0 OCM has been assembled
with a new desiccant plug to ensure the
area surrounding the sample cell is free of
any moisture. As the desiccant absorbs
moisture, it will change from a light blue to a
light pink at the saturation point. The
desiccant should be promptly replaced upon
turning pink or annually (from the date of
installation) if no color change is noted.
Refer to 9.3. Replacement Parts for the
replacement desiccant plugs part number.
Failure to regularly replace the
desiccant plug can result in
incorrect operation and measurement.
9.2.1.1 Desiccant Plug Replacement
For replacement of the desiccant plug,
perform the following steps; refer to the
General Arrangement Drawings:
1. Move the inlet valve to the maintenance
position.
2. Unscrew the existing desiccant plug.
3. Remove the new desiccant plug from its
packaging.
4. Install the new desiccant plug by hand-
tightening onto the monitor.
5. Move the inlet valve to the flow position.
9.2.2 Cleaning the Sample Cell
Sample cell cleaning frequency is
dependent on the quality of the water
sample being monitored. The sample cell is
unlikely to clog, but over time residue can
build up on the inside of the quartz cuvette,
especially where oily water is involved. A
fouled or discolored sample cell can result
in low or erratic readings. Sample cell
cleaning steps are outlined in Section 5.3.2.

TD-1075.0 Oil Content Monitor
Operation Manual
20
Be sure to move the inlet valve to
the flow position after completing the
cleaning.
9.2.3 Calibration Check
The calibration should be checked using the
provided Check Solution. If the Check
Solution does not read within the allowed
tolerance, clean the sample cell. If the
calibration discrepancy persists, contact the
factory-authorized dealer. The TD-1075.0
OCM must be re-calibrated on a periodic
basis as indicated on the calibration
certificate. Per DNV TAP No. 771.61
regulations, this calibration must be
conducted by the factory-authorized dealer.
Contact the factory-authorized dealer within
the two months prior to the expiration of the
calibration certificate to arrange re-
calibration.
