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.
This feature can be enabled or disabled in Gauge Configuration.
The gauge must be in the Normal Mode with the gauge port
exposed to normal atmospheric pressure.
While in the Zero Tare mode, the gauge will not respond to any
changes in pressure. The loop current will maintain its last value.

To exit with no changes, press SEL.
If not within approximately 3%
full scale of zero,
Err0

displayed and no changes are
allowed. Pressure must be removed from the

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.

If a pass code is required, the upper display will
indicate _ _ _ _ with the left-most position blink-
ing, and the lower section will indicate
TSTPC
(Test Pass Code). See the "Enter Configuration
Pass code" section of this manual to enter the
pass code and continue.
Next, the upper display will indicate the applied
pressure and the units display will be blinking.
While the TEST button is pressed, the display and
loop current are switched, independent of the
actual pressure, to a level determined by the test
setting.
TEST
is indicated on the lower display.
Note: The gauge will not respond to changes in
applied pressure while the TEST button is held.
Pressing the
s
or

buttons while pressing the
TEST button will raise or lower the test value.
When the TEST button is released, the setting is
stored in non-volatile memory and the gauge will
operate normally.
Press SEL to exit the Test Mode and return to
the Normal Mode.

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.
To power up the gauge, press and release the
SEL button.
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

The gauge will return to Normal Mode when loop
