DPG 1000B & DPG 1000BBL DIGITAL PRESSURE GAUGE USER’S GUIDE
1.0 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. Use fittings appropriate for the pressure range of the gauge. Do not apply vacuum to gauges
not designed for vacuum operation.
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.
2.0 Operation – Ranges up to 1999
Press the round button on the front of the gauge to activate the display. The gauge will stay on for a period of time
determined by the auto-shutoff time. The gauge can be shut off at any time by pressing the button again. Display
backlighting on DPG1000BBL models is on whenever the gauge is on. If the gauge was ordered without auto
shutoff it will stay on until the button is pressed or until the batteries are depleted. Turn gauge off when not in use
to conserve battery.
3.0 Operation – 3000 psi, 5000 psi Ranges
Press and hold the pushbutton for approximately 1 second. The full-scale range is indicated, display segments are
tested, and then the reading is displayed.
Power-Up with One-Touch Zero (Gauge reference models only)
1. Make absolutely certain no pressure is applied to the gauge. The gauge port 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
is displayed and then release the button. This indicated
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
and the actual measured pressure. The gauge must be
powered down to reset the error condition.
Normal Operation
Following the start-up initialization, the display indicates the pressure reading updated approximately 3 times per
second. The auto shutoff timer starts when the gauge is powered up or whenever the button is pushed, unless the
gauge was ordered without an auto shutoff time (-ON option).
If excessive vacuum is applied to a pressure-only gauge, the display will indicate
until the vacuum is re-
leased. Applying vacuum to a gauge designed for pressure may damage the pressure sensor.
