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.

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 BetaGauge PIR will be “Cust”.

Turning the backlight on and off: Press the ENTER button.
Zeroing the display: Press and hold the ZERO button.
MAX/MIN: The BetaGauge PIR 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
