Instructions
Backup Power Mode Operation
The power supply for the Backup Power mode takes approximately
two hours of operation in the Normal Mode to fully charge the
backup power supply from the loop supply.
If loop power is lost, the gauge will automatically
switch to the Backup Power mode.
The low power indicator will flash, and the Loop-
Tracker LED will be off. The pressure will display
for 15 seconds, then the gauge will shut off.
To power up the gauge, press and release the
SEL button.
After initialization, the gauge will indicate the
applied pressure for 15 seconds.
To power-up the gauge for a longer period of time
and override the auto shutoff, press and hold the
SEL button until the display indicates On.
The gauge will indicate the pressure until the
backup power is depleted. A fully charged
backup supply will last up to 40 minutes.
Press SEL to manually power OFF the gauge.
The gauge will return to Normal Mode when loop
power is restored.
Out-of-Range Indications
If excessive vacuum is applied to a pressure-
only gauge, the display will indicate an out-of-
range indication of –Err. Applying vacuum to
a pressure-only gauge can damage the sensor.
If excessive vacuum is applied to a vacuum-
pressure gauge, the display will indicate an out-
of-range indication of – I – – – or –I.–.–.– will
be displayed depending on model.
If 112.5% over-range pressure is applied, an
out-of-range indication of 1 – – – or 1.–.–.– will
be displayed depending on model.
Enter Configuration Pass Code
When a pass code is required, the upper display will indicate _ _ _ _ ,
and the lower display will indicate CFGPC, CALPC, or TSTPC
depending on the feature being accessed.
To cancel, press the SEL button without entering any numbers. If no
buttons are pressed, the gauge will revert to normal operation after
15 seconds. To proceed, enter the user-defined pass code. 3510 is
the factory default, but it is user-modifiable.
The first position will be blinking.
Use the s or t buttons to set the left-most
digit to 3.
Press and release the SEL button to index to the
next position.
The 3 will remain, and the second position will
be blinking.
Use the s or t buttons to select 5.
Press and release the SEL button to index to the
next position.
3 5 will remain, and the third position will be
blinking.
Use the s or t buttons to select 1.
Press and release the SEL button to index to the
next position.
3 5 1 will remain, and the fourth position will
be blinking.
Use the s or t buttons to select 0.
Press and release the SEL button to proceed with
configuration procedures.
Note: If an incorrect pass code is entered, the
gauge will return to the start of the pass code
entry sequence.

Zero/Tare Mode
Zero/Tare applies to gauge reference models only. Absolute refer-
ence gauges do not use the zero feature since they read atmo-
spheric pressure under normal conditions.
