1.3 The Instrument and Touch Pad
The keypad has five buttons: ON/OFF, CAL, s, t, and ↵↵. The ON/OFF
button is used to turn the instrument on and off. The CAL button, when
pressed, initiates the calibration mode of the instrument. The ↵↵ button,
when pressed, indicates to the instrument that it should take a reading. The
sand tbuttons are used to change the calibration points.
2. Safety
This manual contains basic instructions that you must follow during the
operation, care and maintenance of the instrument. The safety protection
provided by this equipment may be impaired if it is used in a manner not
described in this manual. It is recommended that all operators should read
this manual prior to working with this instrument.
In certain instances NOTES, or helpful hints, have been highlighted to give
further clarification to the instructions. Refer to the Table of Contents to
easily find specific topics and to learn about unfamiliar terms.
3. Normal Operation
This instrument allows you to measure the turbidity of a grab sample. The
turbidity is reported in Nephelometric Turbidity Units (NTU). Readings
above 1100 NTU are outside the range of this instrument.
During normal operation, the instrument will have the last valid turbidity
reading indicated on the display (see illustration below).
If the sample that you are measuring has a turbidity that is higher than that
which the instrument can measure, the instrument will indicate this as an
over-range condition:

6
In certain instances, during normal operation, the instrument briefly displays
a row of dashes across the display.
This indicates that either the instrument is performing an auto-ranging
function, or the sample has a substantial amount of bubbles. If the dashes
remain for an extended period of time please ensure that the sample does
not have a large amount of bubbles present; if there are not bubbles present,
please contact the distributor for further assistance and guidance (refer to
section 5.2).
3.1 Routine Measurement
The CyberScan IR TB100 measures and reports the turbidity of a sample in
Nephelometric Turbidity Units (NTU’s).
Note: Nephelometric turbidity units (NTU’s) are numerically equivalent to
Formazin turbidity units (FTU’s) (See Glossary).
Turn on the instrument by pressing the ON/OFF button continuously for 1
second. Allow one and a half minutes warm-up period while preparing for
the turbidity measurement as described in the following steps:
1. Sample approximately 100 ml of your process, as you would normally
do for turbidity measurement.
2. Obtain a clean and dry sample cuvette.
3. Rinse the cuvette with approximately 10 ml of the sample water (2/3 of
cuvette volume), capping the cuvette with the black light shield (cuvette
top) and inverting several times. Discard the used sample and repeat the
rinsing procedure two more times.

7
4. Completely fill the rinsed cuvette (from step 3) with the remaining
portion (approximately 15 ml) of the grab sample and then cap the
cuvette with the supplied cap. Ensure that the outside of the cuvette is
dry, clean and free from smudges.
5. Place the cuvette into the instrument and press it down until it snaps
fully into the sample well. Index the cuvette by pressing and holding
down the ↵↵ button while rotating the cuvette to identify the lowest
reading (the displayed turbidity is continuously updated on the display).
Once the cuvette is indexed, release the ↵↵ button to display the
measured turbidity (see Glossary for more information on indexing a
cuvette).
6. Repeat steps 1 through 5 for all of your samples.
WARNING: NEVER pour liquid directly into the sample well of the
instrument. Always use a cuvette. The instrument will only accurately
measure the turbidity of a sample when cuvettes sealed with the black cap
are used. The black cap serves as both seal and a light shield.
Note: The instrument will automatically power off after approximately 5
minutes to conserve battery power if no buttons are pressed.
4. Instrument Calibration
The CyberScan IR TB100 was calibrated and tested prior to leaving the
factory. Therefore, it is possible to use the instrument directly out of the
box. However, re-calibration of the instrument is recommended to help you
become familiar with the operation of the instrument and the calibration
procedures. In addition, re-calibration is recommended at least once every
one month for optimum accuracy.
The CyberScan IR TB100 requires 4 standards to be fully calibrated. During
calibration, the instrument performs several system self-diagnostics. As
such, several warning messages may be displayed. If the instrument detects
an irregularity (detectors or lamp) a warning message will be displayed
upon exiting the calibration mode. If this occurs please attempt to rectify
the warning message yourself, or contact the authorized technical services
department (see section 5.2). In any event, the instrument will continue to
read the turbidity with a decreased accuracy until the error is rectified.

4.1 Calibration Standards
We recommend that you use the following materials during calibration to
achieve the accuracy stated in this manual:
1. CAL 1: 1000 NTU Calibration Standard
2. CAL 2: 100 NTU Calibration Standard
3. CAL 3: 10.0 NTU Calibration Standard
4. CAL 4: 0.02 NTU Calibration Standard
It is well known that diluted Formazin is unstable. If you choose to use
Formazin to calibrate the instrument, ensure that you are using a fresh stock
suspension of Formazin to achieve the accuracy quoted for the instrument.
Calibration standards offered are more stable than Formazin and have a
limited shelf life of 6 months. If you use the stable calibration standards to
calibrate the instrument, review the expiration date (indicated on cap label)
to ensure that the standards have not expired.
4.2 Indexing the Calibration Standards
The United States Environmental Protection Agency (US EPA)
recommends that cuvettes used for any instrument calibration or sample
measurement be indexed. To comply with this recommendation, each
calibration standard is supplied with an indexing ring and each instrument
has a reference point for quick and repeatable indexing of the calibration
standard. To index a calibration standard perform the following steps:
1. While holding down the ↵↵ button, slowly rotate the calibration standard
one complete revolution (360°) pausing between increments to allow the
display to update.
2. While rotating the standard, observe the turbidity reading and locate the
cuvette position with the lowest turbidity reading.
3. With the calibration standard positioned at the location having the
lowest turbidity reading, install the Indexing Ring over the black light
shield on the standard so that the pointer of the Ring aligns with the
reference arrow on the instrument.
4.3 Calibration Procedures
1. Select the calibration function of the instrument by pressing the CAL
button once. The “CAL” block will be illuminated on the display with
“1” indicating the standard required for this step of the calibration. This
is the first standard that should be used in a full calibration.

9
2. Insert the 1000 NTU standard (CAL 1 in the figure above) into the
sample well and press down until the cuvette snaps fully into the
instrument. Align the indexing ring with the arrow on the instrument
(see section 4.2 if you have not already indexed the Standard).
3. Wait for the reading to stabilize. Once the reading has stabilized press
the ↵↵ button to indicate to the instrument that it should calibrate on this
point. You will see something similar to the display shown below.
4. When the instrument has completed calibration on this point, it prompts
you to insert the next calibration standard into the sample well (CAL 2).
5. Repeat steps 2-4 for each calibration standard. When you calibrate on
CAL 4 (turbidity free water), the instrument will automatically exit out
of calibration returning back to the normal operating mode.
Notes:
1. During calibration, the screen actively displays the current turbidity
value. After the CAL value changes, it is common for the display to not
report the exact turbidity of the standard as it either is expecting a new
standard or has not yet calibrated the new standard.
2. If you wish to exit the calibration mode you may do so at the end of any
step by pressing the CAL button. The instrument will accept only the
values calibrated prior to exiting.

5. Troubleshooting
The instrument routinely performs self-diagnostics, and will automatically
generate messages to provide you with specific diagnostic information.
5.1 System Warning Messages
Automatic warning messages are generated to provide you with specific
diagnostic information about the instrument. These messages are for your
use and do not indicate a reduction in the performance of the instrument or a
failure of any component in the instrument.
Flashing Battery Symbol: A flashing battery on the display indicates that
the batteries need to be replaced. Under this condition, you should replace
the batteries as soon as possible to ensure that the instrument will continue
to function properly. If the batteries get too low to accurately measure, the
instrument will turn off. The instrument might not turn back on until the
batteries have been replaced. See section 6.2 for more information.
5.2 System Error Messages
Normally, the cause of an error message is external to the instrument. If an
error is identified the instrument will flash the error block (ERR) along with
the error number.

11
The following table lists the error messages and their associated meanings:
Error Associated Meaning Typical Cause
1Lamp failure Lamp has too low an
output for proper turbidity
measurement.
2General Calibration failure: There
is not sufficient signal between
the 0.02 NTU and 10.0 NTU
standards used for calibration
Either the wrong standards
were used in calibration or
there is an internal sensor
failure.
3General Calibration failure: There
is not sufficient signal between
the 10.0 NTU and 100.0 NTU
standards used for calibration
Either the wrong standards
were used in calibration or
there is an internal sensor
failure.
4General Calibration failure: There
is not sufficient signal between
the 100.0 NTU and 1000.0 NTU
standards used for calibration
Either the wrong standards
were used in calibration or
there is an internal sensor
failure.
Err Multiple error conditions are met
6. Routine Maintenance
If you do not plan on leaving the instrument in the supplied carrying case,
when not in use, ensure that the instrument has been turned off and that a
clean sample cuvette fitted with a black cap has been placed in the sample
well. This will ensure that a minimal amount of dust and/or debris will be
able to settle on the optics of the instrument.
6.1 Cuvette Cleaning and Care
Proper measurement of the turbidity of a sample requires the use of a
cuvette that is free of marks, smudges, scratches and any bacterial growth.
Cleaning the cuvette is accomplished by washing the interior and exterior of
the cuvette in a detergent solution. Once cleaned, the cuvette should be
rinsed thoroughly 8 to 10 times with clean distilled water to eliminate the
possibility of detergent buildup and streaking. Cleaned and dried cuvettes
should be stored with the black caps on. The cuvettes can be stored in a
cuvette rack (see accessories and replacement parts list). During normal
operation you may use any typical glass cleaner along with a lint free cloth
or tissue (Kimwipes®), to clean the outside of the cuvettes.

12
Condensation may appear on the cuvette when your sample is very cold and
the relative humidity is high. When this happens, the turbidity that you read
may be higher than the actual turbidity due to the light scattered by the
condensate on the cuvette. If you find yourself in this circumstance you can
alleviate the problem by either coating the cuvette with an anti-fogging
agent, or by running warm water over the cuvette for a short period of time
to warm the sample prior to measurement.
6.2 Battery Replacement
The instrument will periodically require new batteries to function properly.
This will be indicated with a flashing battery indicator on the display. To
replace the batteries:
1. Turn the instrument off and place it upside down on a soft surface.
2. Remove the two screws (A) securing the battery cover (B). Lift cover
off.
3. Remove the old batteries. Place four new “AAA” alkaline batteries (C)
into the battery compartment (ensuring the correct polarity).
4. Replace the battery cover and fasten the two screws carefully to ensure a
watertight seal.
5. Dispose of used batteries in accordance with your local regulations.

Indexing a Cuvette: The United States Environmental Protection Agency
(US EPA) recommends that cuvettes used for turbidimeter calibration or
sample measurement be indexed. To index a cuvette with a sample in it,
slowly rotate the cuvette throughout one complete revolution (360°). While
rotating the sample cuvette, observe the display and locate the position that
the cuvette is in which provides the lowest turbidity reading. This position
is the indexed position of the cuvette. Refer to section 4.2 of this manual to
learn how to index a cuvette in this instrument.
Nephelometric Turbidity Units (NTU): Unit of measure used when
relating the light scattered by a liquid media to the light scattered by a
known concentration of Formazin Polymer. This unit of measure is
recognized as a measure of the optical clarity of an aqueous sample. NTU
is the accepted unit of measurement for turbidity.
Turbidity: 1) A measure of the attenuation of a radiant flux as it passes
through a liquid media, 2) Optical clarity of a liquid, 3) A phenomena
caused by the presence of undissolved matter in a liquid media.
