Martel Electronics BetaGauge PIR PRO - Manual (Page 6)

3. Operation
Power: The standard BetaGauge PIR is supplied with 3 AA
batteries installed. If you purchased the optional 24Volt powered
version, batteries are not installed. Connect a 24V power supply to
the terminal block on the rear of the gauge, noting proper polarity.
Do not install batteries when external power will be used.
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 BetaGauge PIR 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.
