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.
