• Instructions
All units are factory calibrated prior to shipment.
NOTE: Due to the temperature sensitivity of the strain gages within the
sensor, sudden temperature changes, such as holding an unmounted gauge by
the sensor, will cause the readings on the display to fluctuate. Please install
the gauge in your system before determining stability.
1. Zero Trimming:
If it becomes necessary to re-adjust the “Zero” on the display, this can be
accomplished by turning the trimpot marked “Z” just to the left of the On/Off
push button. On the PG-2000 there is either a zero adjustment knob or a black
nylon cover screw. If the gauge has a cover screw, it is necessary to remove the
cover screw to access the zero adjustment pot. An ideal zero is indicated by a
reading of 000 with an intermittently flashing “-” sign.
NOTE: A jewelers screwdriver or an eyeglass repair screwdriver (supplied)
is a suitable instrument. Do not make changes to the Span adjustment (the “S”
pot to the right of the push button) as part of the zero trimming. The Span
should only be changed as part of the re-calibration of a gauge with a known
pressure source.
2. Battery Replacement (9 Volt Type):
The battery can be replaced simply by removing the single screw at the top of
the battery door. Remove the old battery, unplug the cable connector and
replace with Eveready type 216 or equivalent. Replace the battery door and
secure with the self-tapping screw (do not overtighten).
NOTE: For best accuracy, re-calibration (see section below) should be
performed at the time batteries are replaced.
3. Re-Calibration:
This procedure requires a known pressure source of at least ±0.1% accuracy
in order to fully utilize the accuracy potential of the PG-2000. (If not available,
gauge can be returned toAPG for re-calibration.)
Procedure:
A. Ensure the Gauge is at 0 psig (or vacuum if absolute), and adjust the zero
as per instructions in #1.
B. Apply full scale pressure to the pressure port and adjust the span (“S”)
pot until the display reads the correct pressure.

C. Re-check the zero and re-adjust the zero (“Z”) pot if required.
D. Repeat steps B and C, until no further adjustment is required.
4. External Power:
When equipped with this option, the gauge no longer operates from batteries,
but instead is "externally" powered. The unit is powered via a miniature "Phone
Jack" on the back of the unit. The "Tip" connection is the "+Power", and the
"Center" is connected to the "-Power".
It is important that you never remove or insert the "Phone Jack" connector
into the gauge with the power turned on. This can damage the gauge and cause
it to fail. Only turn the power on after the "Phone Jack" has been inserted into
the external power connector.
