Introduction
The IPI combines the high accuracy of digital electronics with the
convenience and ease of use of an analog test gauge. Accurate to ±
0.05% FS, the IPI can be used as a calibration reference, or in any
application where high accuracy pressure measurement is required.
Many user configurable functions have been designed into the IPI
including sampling rate, TARE, damping, auto shut off, and min-max.
Once the gauge is configured, settings can be locked and password
protected to prevent unauthorized changes to configuration.

function. Once a function has been set, press ENTER to exit the
configuration menu, or CONFIG to continue with further configuration. In
order, the configuration menu and operation is as follows:
1. Engineering Units set. The unit is shipped configured to display
PSI. By pressing the ▲ and ▼ (ZERO and MAX/MIN) keys you can
scroll forward and backwards through the 18 standard engineering
units plus a one custom unit/scale. When the desired unit is displayed,
press ENTER or CONFIG. Pressure will now be displayed in the
chosen engineering units.
See the Specifications section of this manual for a list of available
engineering units. See the Supervisory Mode section for details on
setting up custom units.
2. Set Auto Off. The auto-shut off can be set in 1 minute increments
from 1 to 30 minutes or “off” (continuous operation). The unit is
shipped set for 30 minutes. Use the ▲ and ▼ keys to set the desired
interval. The “off” setting is at the low end of the choices, below 1
minute.
3. Display battery voltage. Actual voltage and a percent of life
bargraph indicate battery condition
4. Display actual temperature. The IPI is temperature compensated,
this displays the temperature measured by the internal sensor. The
value can be set to degrees F or degrees C using the arrow keys.
5. Set damping. Choices are “on” and “off” set with the ▲ and ▼ keys.
Turning damping on will smooth readings from pulsating pressure
sources.
6. Set sample rate: This determines how often pressure is sampled and
the display is updated. Choices are 0.5, 1, 3, and 10 samples/
second. Note that 10/sec provides the fastest response time.
7. Set TARE. This allows you to set a constant offset value, which is
then subtracted from the measured pressure. For example if a TARE is
set at 30 PSI, and the measured pressure is 37 PSI, the displayed
value will be 7 PSI.
A pressure of 27 PSI would be displayed as –3 PSI.
The tare value is set manually with the ▲ and ▼ keys, and is based on
the engineering units and resolution selected for display. TARE value
can be set to the maximum range of the gauge.
The bar graph will always display the actual pressure based on the full
range of the gauge regardless of the tare setting. This is done for
safety to insure that even with a “0” reading that pressure is being
applied to the gauge.
8. Function Lock: Access to each of the settable parameters above can
be turned “off” once set, to prevent unauthorized changes to
configuration. This is accomplished through a password protected
“supervisory mode”. Press ENTER to access the supervisory mode, or
CONFIG to return to normal operation.
Supervisory Mode
Push the CONFIG button to access the user-settable functions on the
indicator. Each time the CONFIG button is pressed; the display advances
to the next function. Press CONFIG repeatedly until “FUnC LOCK” is
displayed.
Press ENTER when “FUnC LOCK” is displayed, 0
PWRD
will be displayed on
the gauge. The password to enter supervisory mode is 101, set using the
▲ and ▼ keys. Holding a key continuously will cause the display to
advance more quickly for faster setting. The password is factory set and
cannot be changed.
1. Your IPI is shipped from the factory with all setting access “unlocked”
or available to be changed.
2. In supervisory mode each of the parameters can be locked or
unlocked using the ▲ and ▼ keys. Select LOC (lock) for those
parameters you do not want to be accessible, and UnLOC (unlock) for
those can be accessed.
3.
In order, the functions that can be unlocked, locked or accessed are:
• Zero function (enable/disable)
• Set pressure units (enable/disable)
• Auto shutdown adjustment (enable/disable)
• Damping settings (enable/disable)
• Sample rate setting (enable/disable)
• Tare setting (enable/disable)
• Custom engineering units (set scale factor)
4. Use the CONFIG key to scroll through the above choices, and the ▲
and ▼ keys to lock and unlock features. Press CONFIG to continue
scrolling through the parameters, pressing ENTER at any point saves
your settings and returns the gauge to normal operation.
When a function is “locked”, it cannot be accessed or changed from
its current state. To change a locked function, enter the supervisory
mode, and unlock the function. Once it is changed, you may enter
supervisory mode to lock access again.
5. Setting a custom engineering unit or scale: The last menu choice in
supervisory mode is SET FACTR. This allows you to set a multiplier
5
6
factor from 0.001 to 100, creating a custom scale. The set factor will
be multiplied by the PSI measured, the result will be displayed.
For example: 40 PSI is the equivalent of 1000 lbs of product in a tank.
You want to display the product weight , using a 100 PSI gauge. By
setting a factor of 25, a 40 PSI pressure would display as 1000 (40 x
25). The engineering unit displayed on the IPI will be “Cust”.
Normal Operation
Turning the backlight on and off: Press the ENTER button.
Zeroing the display: Press and hold the ZERO button.
MAX/MIN: The IPI stores minimum and maximum pressure values in
memory. Pressing the MAX/MIN button once will display the minimum
pressure from memory. Pressing the MAX/MIN button again will display
the maximum pressure from memory. After about 2 seconds, the gauge
returns to normal (live display) operation. To clear the MAX/MIN memory
registers, press and hold the MAX/MIN button for 2 or more seconds until
“CLr” is displayed.
The analog bar graph at the bottom of the display indicates the applied
pressure level relative to the full range of the gauge. Keep in mind that if a
TARE value has been programmed into the gauge, the displayed pressure
will not reflect the true pressure applied.
Changing the Batteries
WARNING
Explosion hazard
Batteries must only be changed in an area known
to be non-hazardous.
Grasp the face ring on the IPI, turn it approximately ¼ turn
counterclockwise and remove. The face of the gauge can now be lifted to
expose the battery holder. Take off the battery hold clip and remove the
batteries. Install three AA batteries noting proper polarity. Note: Use ONLY
AA size batteries and be sure to reinstall the battery holder retaining clip.
Reassemble the case making certain that the face is properly oriented.
If you purchased the optional 24 Volt powered version, the terminals for
power input are located on the rear of the gauge. To apply power simply
connect 24 volts to the rear terminal block taking care to observe proper
polarity.
WARNING
Gauges ordered with the external power option will not come with
batteries installed. Batteries MUST NOT be installed when
operating on external power. External power option gauges are not
approved for hazardous location use.
Battery life
Battery life is about 1500 hours (60 days) of continuous use with the
backlight off. With intermittent use, batteries could last a year or more.
There is a low battery icon in the upper left of the display. It will appear
when battery level is low. Replace batteries per recommendations found in
the specifications section of this manual.
RS-232 Interface
An RS-232 interface is standard on the IPI. Serial communication can be
used for configuration, calibration, and to transfer measurement data from
the gauge. For detailed specifications on the interface and software
communication, contact the factory at 603-434-1433 and request a copy of
our interface manual.
WARNING
The RS-232 interface must not be used in hazardous areas.

Appendix 1: IPI Calibration Procedure
Overview
Calibration adjustment of the IPI is performed electronically via internal
software with the case closed. There are no mechanical adjustments; all
calibration commands and adjustments are done via the keypad, using the
display to guide the user through the calibration process.
Eight calibration points are used in the adjustment program, working from
full scale to zero at pressures equaling 100%, 87.5%, 75%, 62.5%, 50%,
37.5%, 25%, 12.5%, and 0% of full scale plus vacuum.
Note: This is an ambient temperature calibration, and should be performed
at an ambient temperature of 23 °C ± 3 °C (72 °F ± 5 °F). Calibration
outside this temperature range will invalidate the temperature
compensation program in the IPI.
Calibration Interval
You should check performance of the PI at the interval required by your
calibration program. We recommend adjustment when measurement
deviates by more than 75% of the specified accuracy, or 0.04%
Test Equipment
Verification and calibration of the IPI requires pressure and/or vacuum
standards able to produce and indicate pressures from vacuum to the fullscale range of the unit under test. In order to maintain the specified
accuracy of the IPI, standards should have a TUR of 4:1 or better.

Connections:
The PI uses a 1/4 NPT male connection in the pressure input port. Various
adapters may or may not be needed to connect to the pressure standard.
Always make sure the hose, tubing, and fittings etc have a rated working
pressure at or above the pressure of the unit. Also it is important that there
be no leaks when performing calibration; use Teflon tape where
appropriate.
Entering Calibration Mode:
After you have made your connections, turn the power on while holding the
CONFIG key. Use the arrow keys to enter the password. The password is
101. If you have entered calibration mode correctly the display should look
as shown below. The pressure value displayed will be the full-scale value
of the gauge.
