Installation Precautions, Ranges and Engineering Units CTP3B
Installation Precautions
4Read these instructions before using the gauge. Configuration may
be easier before installation. Contact the factory for assistance.
4These products do not contain user-serviceable parts, except
batteries. Contact us for repairs, service, or refurbishment.
4Gauges must be operated within specified ambient temperature ranges.
4Permanent installations must be indoors only. Outdoor or wash
down applications require installation in a NEMA 4X housing.
4Use a pressure or vacuum range appropriate for the application.
4Use fittings appropriate for the pressure range of the gauge.
4Due to the hardness of 316 stainless steel, it is recommended that
a thread sealant be used to ensure leak-free operation.
4For contaminated media use an appropriate screen or filter to
keep debris out of gauge port.
4Remove system pressures before removing or installing gauge.
4Install or remove gauge using a wrench on the hex fitting only. Do
not attempt to turn gauge by forcing the housing.
4Good design practice dictates that positive displacement liquid
pumps include protection devices to prevent sensor damage from
pressure spikes, acceleration head, and vacuum extremes.
p Avoid permanent sensor damage! Do not apply vacuum to non-
vacuum gauges or hydraulic vacuum to any gauges.
p Avoid permanent sensor damage! NEVER insert objects into
gauge port or blow out with compressed air.
Gauges are not for oxygen service. Accidental rupture of sensor dia-
phragm may cause silicone oil inside sensor to react with oxygen.
Display Backlighting
The factory default on-time for display backlighting is 1 minute. It
turns on for one minute when the gauge is first turned on or when-
ever any button is pressed. This also restarts the auto shutoff timer.
In user configuration, the backlight time can be set from 1 to 255
minutes, disabled to save battery life, or set to be on whenever
the gauge is on.
The LED display backlighting may not be apparent under bright
lighting conditions.
Power-Up and Normal Operation
Your gauge is ready for use. It was cali-
brated just prior to shipment with batteries
installed.
Press and hold the center power button
for approximately 1 second. The display
is tested.
The full-scale range in the factory default
units is indicated. If the units were changed
by the user, the full scale range in the
selected engineering units is then dis-
played.
The display test is briefly shown again.
The actual pressure and units are dis-
played. The gauge is ready for use and
readings are updated approximately 3 times
per second
For gauge reference models occasional
flashing of the minus sign is normal and
indicates the gauge is at zero pressure.
Absolute gauges only display zero at full vacuum.
Shutoff
The auto shutoff timer starts at power up and restarts whenever
any button is pressed. The default time is 5 minutes, but can be set
for a variety of times in gauge configuration. If on/off operation is
selected, the gauge will stay on until manually shut off or when the
batteries are depleted. Turn gauge off when not in use to conserve
battery life.
When an auto shutoff time is used, the
display indicates OFF five seconds prior to
shutoff. Press the power button to keep the
gauge on and restart the timer.
To shut the gauge off manually, press and
hold the center power button (about 3-5
seconds) until OFF is displayed.
Error or Out-of-Range Indications
Attempting to zero the gauge with reading
greater than approximately 3% of full-
scale pressure or vacuum will result in an
error condition. The display will alternately
indicate Err 0 and the reading. Press the
power button to reset the error condition.
If excessive vacuum is applied to a pres-
sure-only gauge, the display will indicate
-Err until the vacuum is released. Applying
vacuum to a pressure-only gauge can dam-
age the pressure sensor.
If 112.5% over range pressure is applied , an
out-of-range indication of 1 – – – or 1.–.–.–
will be displayed depending on model.
0rrE

- or -
Press and hold the Zero/Clear button.
Occasional flashing of the minus sign with
zero pressure/vacuum is normal.
The stored zero correction is erased when
the gauge shuts off.
Continue to press the Zero/Clear button until
oooo is displayed then release the button.
The gauge in now zeroed.
Zero the Display
This applies to gauge reference models only. Absolute reference
gauges do not use the zero feature since they read atmospheric
pressure under normal conditions.
Be sure the gauge is in the normal operating
mode. The gauge port must be exposed to
normal atmospheric pressure with no pres-
sure or vacuum applied.

Types of Gauges
Gauge reference sensors always read zero with an open gauge port.
Ranges 1000 psi and higher use a 14.7 psi sealed reference sensor.
They are functionally similar to gauge reference sensors.
Bipolar sensors read positive pressure and vacuum in the same
units, and zero with the gauge port open.
Compound ranges read inHg for vacuum and psig for pressure.
Absolute reference gauges read zero at full vacuum. With an open
gauge port, their readings will vary due to continuously changing
barometric pressure.

Battery Replacement
A low battery indication will be shown in the upper left-
hand corner of the display when the battery voltage falls
sufficiently. The batteries should be replaced soon after the
indicator comes on or unreliable readings may result.
1. Remove the 6 Phillips screws on the back of the unit.
2. Lift up the battery holder if necessary.
3. Remove batteries by lifting up the positive end of the battery
(opposite the spring) taking care not to bend the battery holder
spring.
4. Discard old batteries properly, do not discard into fire, sources
of extreme heat, or in any hazardous manner.
5. Always replace both batteries at the same time with high quality
alkaline batteries.
6. Install batteries with correct orientation. Incorrect polarity will
damage the gauge. The negative (flat) end of each battery
should be inserted first facing the battery holder spring.
7. Replace battery holder and back cover, including the rubber
gasket and reinstall the six screws.

Calibration—Setup and Preparation
Gauges are calibrated at the factory using equipment traceable
to NIST. There is no need to calibrate the gauge before putting
it into service. Calibration should only be performed by qualified
individuals using appropriate calibration standards and procedures.
Calibration intervals depend on your quality control program
requirements, although many customers calibrate annually.
The calibration system must be able to generate and measure
pressure/vacuum over the full range of the gauge and should be
at least four times more accurate than the gauge being calibrated.
A vacuum pump able to produce a vacuum of 100 microns (0.1 torr
or 100 millitorr) or lower is required for vacuum and absolute gauges.
Allow the gauge to acclimate to ambient temperature for 20 minutes.
Install fresh batteries.
Entering Calibration Mode
With the gauge off, press and hold the tbutton, then press the
Power button.
Release all buttons when the display indicates CAL.
The display begins by indicating the full-scale positive pressure
rating of the gauge in the engineering units as configured by the
factory, and then shows all display.
Before the gauge enters the Calibration Mode, the display initially
indicates _ _ _ _ with the first underscore blinking, and with CALPC
(calibration passcode) on the lower display.
Enter the 3510 passcode as described in the Configuration
Passcode section.
Calibration Mode
The gauge remains in the Calibration Mode until restarted manually
or power is removed. Features not related to calibration are dis-
abled and compound range models are set for the same engineer-
ing units for pressure and for vacuum.
The calibration may be performed in any of the available engineer-
ing units as well as percent (PCT).
For greatest accuracy, use the sand tbuttons to select engi-
neering units for calibration with highest number of display counts.
Press and release the Power button when the appropriate engineer-
ing units are displayed. Suggested units are above right.
Compound and Bipolar Gauges
In addition to the steps described above for pressure gauges, apply
full-scale vacuum. The character display will alternate between
-SPAN and CAL. Adjust for a display indication of actual applied
vacuum using the sand tbuttons.
For bipolar and –30.00inHg/+15.00psig compound range models
only, apply 50% full-scale vacuum. The character display will alter-
nate between -MID and CAL. Adjust for a display indication equal to
50% of full-scale vacuum using the sand tbuttons.
User-Defined Passcode Configuration
The factory default passcode 3510 may be changed to a different
value for configuration and/or calibration.
With the unit off, press and hold the sbutton to view and/or
change the user configuration passcode. Then press the Power
button. Release all buttons when the display indicates CFG.
Calibration Passcode
With the unit off, press and hold the tbutton to view and/or
change the user calibration passcode. Then press the Power button.
Release all buttons when the display indicates CAL.
Change Passcode Mode
Before the unit enters the view or change passcode mode, the
display initially indicates _ _ _ _ with the first underscore blinking,
and with CFGPC or CALPC on the character display.
Note: The unit will automatically revert to normal operation if no
buttons are operated for approximately 15 seconds. To cancel and
return to normal operation, press and release the Power button.
Enter access code 1220:
Use the sand tbuttons to set the left-most digit to 1.
Press and release the Power button to index to the next position.
The 1 will remain, and the second position will be blinking.
Use the sand tbuttons to select 2.
Press and release the Power button to index to the next position. 1
2 will remain, and the third position will be blinking.
Use the sand tbuttons to select 2.
Press and release the Power button to index to the next position. 1
2 2 will remain, and the fourth position will be blinking.
Use the sand tbuttons to select 0.
Press and release the Power button to proceed.
Note: If an incorrect access code was entered, the gauge will return
to the start of the access code entry sequence.
Once the access code has been entered correctly, the display will
indicate the existing user-defined passcode with CFGPC or CALPC
on the character segments.
Press the sor tbutton to select the first character of the new
passcode.
When the correct first character is being displayed, press and
release the Power button to proceed to the next passcode character.
