Installation Precautions Tighten/remove with wrench on hex fitting only. Do not attempt to rotate gauge by turning housing. Use fittings appropriate for the pressure range of the gauge. Do not apply vacuum to gauges not designed for vacuum 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. The DPG1100AD and DPG1100ADBL can be powered by any AC source of 8 to 24 VAC 50/60 Hz, or any DC source of 9 to 32 VDC. The gauges can be used with inexpensive unregulated low voltage AC or DC power supplies. The type and magnitude of the supply voltage have negligible effects on the gauge calibration as long as it is within the voltage ranges stated above. No polarity needs to be observed when connecting a DC supply.

After the gauge is installed, route the wires safely and connect the AC adapter’s wires to the gauge cable. Lastly, plug the AC adapter into a 115 VAC outlet. The only important consideration is to ensure that the gauge supply voltage does not fall below 8 VAC RMS if AC power is used, or 9 VDC if DC power is used. Operation with less than these values may cause erratic or erroneous readings. If your application requires operation of multiple gauges from the same power supply, consult the factory for wiring recommendations. Operation When a supply voltage is applied, the gauge will be ready to use. If the gauge display is off, press the center button to turn the gauge on. If the gauge is in the power- on state and the power is disconnected, the gauge will turn on when power is reapplied. The gauge can be left on continuously or turned off when not in use. DPG1100ADBL model display backlighting will be on whenever gauge is on.

GAUGE reference units may be re-zeroed without affecting the span calibration. The gauge port must be open to the ambient with no pressure or vacuum applied. Adjust the Zero control until the gauge reads zero with the minus (–) sign occasionally flashing. Span calibration should only be attempted if the user has access to a pressure reference of known accuracy. The accuracy of the calibration equipment should be at least four times the gauge accuracy. Zero calibration must be done before span calibration. Record readings at three to five points over the range of gauge and adjust span control to minimize error and meet specifications. ABSOLUTE reference gauges require vacuum generation and atmospheric pressure measurement equipment for accurate calibration and thus are more difficult to calibrate in the field. Gauges may be returned to Omega Engineering for recalibration.
