Installation and Precautions
Install or remove gauge using wrench on hex
fitting only. Do not attempt to tighten by turning
housing or any other part of the gauge.
See label on back of gauge for range!
Use fittings appropriate for the pressure range of
the gauge.
Do not apply vacuum to gauges not specified for
vacuum operation. Per manent damage not
covered by warranty will result to the sensor.
Due to the hardness of 316 stainless steel, it is
recommended that a thread sealant be used to
ensure leak-free operation.
NEVER
insert objects into the gauge port or blow
out with compressed air. Permanent damage not
covered by warranty will result to the sensor.
Absolute Reference Gauges
These models have engineering units shown on
the rear label such as PSIA, INHGA, INH2OA,
ZIN2A, BARA, MBARA, KPAA, TORR or TORRA,
MMHGA, KGCMA, ATMA. The “A” indicates
absolute reference. These ranges display
atmospheric pressure when the gauge port is
open to the atmosphere. They display zero at
high vacuum.
When the gauge port is open to the atmosphere,
it is normal for the reading to constantly change
in response to atmospheric pressure changes.
Do not adjust the calibration controls!
Display Backlighting (ADBL models)
Red LED display backlighting on ADBL models is
on whenever the gauge is on. Backlighting may
not be apparent under bright lighting conditions.
Operation – Ranges up to 1999
Press the round button on the front of the gauge
to activate the display. The gauge can remain on
at all times if desired. The gauge can be shut off
at any time by pressing the button again.
Operation – Rang es 2000 and up
including 3000 psi, 5000 psi
These ranges have a 4-digit display with a lower
alphanumeric display. If the gauge is off, press
and hold the pushbutton for approximately 1
second. The full-scale range is indicated, display
segments are tested, and the reading and units
are displayed.
Following the start-up initialization, the display
indicates the pressure reading updated
approximately 3 times per second and the units.
The gauge can remain on at all times if desired.
To shut off the gauge manually at any time, press
and hold the pushbutton until the display
indicates
O F F
and then release.
Power-Up With One-Touch Zero –
Ranges 2000 and up including 3000 psi,
5000 psi
1. Make absolutely certain no pressure is applied
to the gauge. The gauge por t should be
exposed to normal atmospheric pressure. Note
that the zeroing function may only be activated
at power-up and the stored zero correction is
erased when the gauge is shut off.
2. Press and hold the pushbutton.
3. The full-scale range is indicated and the
display segments are tested.
4. Continue to press the pushbutton until
o
o o
o o
o o
o
is displayed and then release the button. This
indicates that the gauge has been zeroed.
5. The actual pressure is displayed.
Attempting to zero the gauge with pressure
greater than approximately 3% of full-scale
applied will result in an error condition, and the
display will alternately indicate
E
r r
0
and the
actual measured pressure. The gauge must be
powered down to reset the error condition.
Absolute reference gauges do not use the zero
feature since they read atmospheric pressure
under normal conditions.
Out of range indication – Ranges 2000
and up including 3000 psi, 5000 psi
If excessive vacuum is applied to a pressure-only
gauge, the display will indicate
–
E
r r
until the
vacuum is released. Applying vacuum to a gauge
designed for pressure may damage the pressure
sensor. If excessive pressure is applied (112.5%
over range), an out-of-range indication of
i
– – –
or
i
– . – . – . –
will be displayed depending on
model.
