2.0 IPI Mk. II Display and Controls
3.0 Operation
Power: The standard IPI Mk. II is supplied with 3 AA batteries installed.
Push the power button momentarily to turn the unit on. Push it again to turn
it off.
Set-up and configuration:
Push the CONFIG button to access the user-settable functions on the
gauge. Each time the CONFIG button is pressed; the display advances to
the next 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 Mk. II 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.

4.0 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, 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 Mk. II 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
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 Mk. II will be “Cust”.

5.0 Normal Operation
Turning the backlight on and off: Press the ENTER button.
Zeroing the display: Press and hold the ZERO button.
Note: For absolute versions of the gauge pressing the zero key will prompt
the user to enter a barometric reference pressure. Use the ▲and ▼arrow
to adjust the reading as required. Then press ENTER.
MAX/MIN: The IPI Mk. II 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.
