Basic Configuration
Accessing the Internal Buttons
Remove the 6 Phillips screws on the back of the unit.
The two internal buttons are located near the lower right and left
corners of the circuit board.
Engineering Unit Selection
Engineering unit selection (except compound ranges) is done
via internal buttons to help prevent accidental or unauthorized
changes. The selected engineering unit is stored in non-volatile
memory and will be retained even with the gauge off or batteries
removed. The available engineering units depend on the sensor
range and display resolution.
Compound (inHg/PSIG) gauges must be changed to display single-
unit vacuum/pressure readings in the Advanced Configuration mode
before different engineering units can be selected.
The default engineering units are mathematically converted to the
newly selected engineering unit. When the gauge is powered up,
the originally configured range is displayed and then the conversion
with the selected engineering unit is displayed.
Powered the gauge up by holding the front button for 1 second.
Press and hold the internal UP button.
Release the button when the engineering units begin to flash.
Use the UP and DOWN buttons to scroll through the list of engineer-
ing units available for the pressure range of the sensor.
When the desired units are displayed, press and release the front
button to save the selection and return to normal operation.
Note: The gauge will automatically revert to normal operation if no
buttons are operated for approximately 15 seconds.
Replace the rear cover taking care not to pinch the power wires
between the cover and the case.

Advanced Configuration
User configuration allows requires a pass code for access and
allows more features to be configured.
Remove the rear cover to gain access to the buttons located near
the lower right and left corners of the circuit board.
With the gauge off, press and hold the UP button. Then press the
front button. Release all buttons when the display indicates CFG
and the program version then the full-scale range is indicated and
the display is tested.
The display then indicates _ _ _ _ with the first underscore blink-
ing, and with CFGPC (configuration pass code) on the character
segments.
Note: The gauge 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 front button
without entering any pass code characters.
Pass Code Entry
The factory default is 3510, but this may be changed by the user
under the Pass Code Configuration section.
1. Use the UP or DOWN buttons to set the left-most digit to 3.
2. Press and release the front button to move to the next position.
The 3 will remain, and the second position will be blinking.
3. Use the UP or DOWN buttons to select 5.
4. Press and release the front button to index to the next position.
35 will remain, and the third position will be blinking.
5. Use the UP or DOWN buttons to select 1.
6. Press and release the front button to index to the next position.
351 will remain, and the fourth position will be blinking.
7. Use the UP or DOWN buttons to select 0.
8. Press and release the front button to proceed with configuration
procedures.
If an incorrect pass code is entered, the gauge will return to the
start of the pass code entry sequence.
Factory/User Configuration
The upper display section will be blank, and the lower section will
display either USER_ or FCTRY.
If USER_ is selected, the user configuration can be modified as
described in the following steps.
To select USER_, press and release the DOWN button.
The lower display will indicate USER_.
Press and release the front button to continue.
If FCTRY is selected, the existing user configuration will be replaced
by the original factory configuration.
To select FCTRY, press and release the UP button.
The lower display will indicate FCTRY.
Press and release the front button to restore the factory configura-
tion and restart the gauge.
Max/Min Configuration
Use the UP and DOWN buttons to select from the following:
MX/MN Both highest and lowest values will be captured
MX/---
Only highest value will be captured
--/MN
Only lowest value will be captured
--/--
Capture feature is disabled
Press and release the front button to move to the next parameter.
Max/Min Memory
The upper display section will indicate clr.
Use the UP and DOWN buttons to select from the following:
AUTO
Automatically clear max. and min. values when the
gauge is powered off
MAN
Manually clear max. and min. values
Press and release the front button to move to the next parameter.
Gauge Type Configuration
This will only appear with 15, 100, or 200 psig ranges that were
originally ordered as compound gauges.
Use the UP and DOWN buttons to select from the following:
-/+EU
Vacuum is indicated as negative pressure in the
selected engineering units
CMPND Vacuum is negative INHG, pressure is PSIG. This setting
will disable engineering unit selection.
Press and release the front button to save the user configuration
and restart the gauge.
Replace the rear cover taking care not to pinch the power wires
between the cover and the case.

Calibration Preparation
All gauges are factory calibrated using NIST traceable calibration
equipment. Calibration is not required before using the gauge.
Calibration intervals depend on your quality standards, but annual
re-calibration is customary.
Calibration equipment is not required to zero gauge reference
ranges. Absolute reference ranges may be zeroed with application
of full vacuum.
Span calibration should only be performed using appropriate cali-
bration procedures with calibration standards that are at least four
times more accurate than the gauge being calibrated.
The calibration system must be able to generate and measure pres-
sure/vacuum over the full range of the gauge. 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.
Connect gauge to a 8-24 VAC 50/60 Hz or 9-32 VDC power supply.
Allow the gauge to equalize to normal room temperature for
approximately 20 minutes before calibration.
Remove the rear cover to gain access to the UP and DOWN buttons
located near the lower right and left corners of the circuit board.
