Installation and Precautions 4 Read these instructions before using the gauge. Contact the factory for assistance. 4 These products do not contain user-serviceable parts. Contact us for repairs, service, or refurbishment. 4 Gauges must be operated within specified ambient temperature ranges. 4 Outdoor or wash down applications require a NEMA 4X gauge or installation in a NEMA 4X housing. 4 Use a pressure or vacuum range appropriate for the application. 4 Use fittings appropriate for the pressure range of the gauge. 4 Due to the hardness of 316 stainless steel, it is recommended that a thread sealant be used to ensure leak-free operation. 4 For contaminated media use an appropriate screen or filter to keep debris out of gauge port. 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 power supply. An inexpensive unregulated low voltage AC or DC power supply can be used. After the gauge is installed, route the wires away from heat sources and moving equipment and connect the low-voltage power source to the gauge wires. Ensure that the gauge supply voltage does not fall below 8 VACRMS 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. When operating multiple gauges from the same power supply, refer to the mA rating in the specifications to ensure adequate power. Note that standard 24 VAC transformers often operate at voltages well over the gauge’s 24 VAC limit. Absolute Reference Gauges 4 Install or remove gauge using a wrench on the hex fitting only. Do not attempt to turn gauge by forcing the housing. 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. 4 Good design practice dictates that positive displacement liquid pumps include protection devices to prevent sensor damage from pressure spikes, acceleration head, and vacuum extremes. 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! p Avoid permanent sensor damage! Do not apply vacuum to non-vacuum gauges or hydraulic vacuum to any gauges. Display Backlighting (ADBL models) 4 Remove system pressures before removing or installing gauge. p Avoid permanent sensor damage! NEVER insert objects into gauge port or blow out with compressed air. Gauges are not for oxygen service. Accidental rupture of sensor diaphragm may cause silicone oil inside sensor to react with oxygen. p NEVER connect the gauge wires directly to 115 VAC or permanent damage will result. WARNING: This product can expose you to chemicals including lead, nickel and chromium, which are known to the State of California to cause cancer or birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov 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 button on the front of the gauge to activate the display. The gauge can be shut off at any time by pressing the button again. If the gauge is in the power-on state and the power is disconnected, the gauge will turn on when power is reapplied. 3 ft long, 2-conductor, 22 AWG cable 31/2 digit or 41/2 digit display The gauge port must be exposed to normal atmospheric pressure with no pressure applied. The zero function is only used at power-up and the stored zero correction is erased when the gauge is shut off. Press and hold the front button. The full-scale range is indicated and the display is tested. Continue to press the button until oooo is displayed and then release the button. The gauge is now zeroed and ready for use with 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 Err0 and the actual measured pressure. The gauge must be powered down to reset the error condition. Following the start-up initialization, the display indicates the pressure reading updated approximately 3 times per second. If excessive vacuum is applied to a pressure-only gauge, the display will indicate –Err 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. Display backlighting for BL models is on whenever the gauge is on. The backlighting will not be apparent under bright lighting conditions. To shut off the gauge at any time, press and hold the button until the display indicates OFF (about 5 seconds) and then release. 3 ft long, 2-conductor, 22 AWG cable 31/2 digit or 41/2 digit display Allow 1” clearance Allow 1” clearance PSIG Zero Span Zero OMEGA Engineering Inc. / Made in USA OMEGA Engineering Inc./Made in USA Turn at hex fitting only! 0.75” 3.38” The gauge may be zeroed at power-up by following the procedure below. This feature corrects small deviations from zero due to temperature changes. Absolute reference gauges do not use the zero feature since they normally read atmospheric pressure. 3.0” PSIG /4”NPT When the supply voltage is applied, the gauge will go through a power-up sequence. The full-scale range is indicated, display segments are tested, and then the reading and units are displayed. 1100AD and 1100ADBL (NEMA 4X) 2.88” 1 Press and hold the front button for approximately 1 second if the gauge does not turn on when power is applied. The display indicates the pressure reading updated approximately 3 times per second. The gauge can be left on continuously or turned off when not in use. Display backlighting for BL models is on whenever the gauge is on. The backlighting will not be apparent under bright lighting conditions. 1000AD, 1001AD, 1000ADBL Span Operation – Ranges 2000 and up including 3000 psi, 5000 psi 1.65” Turn at hex fitting only! 0.75” /4”NPT 1 3.5” 2.0” DPG1000AD, DPG1001AD, DPG1000ADBL, DPG1100AD, DPG1100ADBL Calibration of Ranges 2000 and up including 3000 psi, 5000 psi NOTE: Calibration Information All gauges are factory calibrated on NIST traceable calibration equipment. No calibration is required before placing the gauge into service. Gauges can be returned to Omega Engineering for factory certified recalibration. NIST traceability is available. Gauges can also be recalibrated by any metrology lab with pressure calibration equipment at least four times more accurate than the gauge. Absolute reference models display atmospheric pressure if the gauge port is open to the ambient. It is normal for the reading to constantly change in response to atmospheric pressure changes. Vacuum generation and atmospheric pressure measurement equipment for accurate calibration and thus these are more difficult to calibrate in the field. DPG1000AD, DPG1001AD, DPG1000ADBL Ranges above 2000 Calibration Preparation – All Models All gauges are factory calibrated using NIST traceable calibration equipment. Calibration is not required before using the gauge. Calibration intervals depend on your quality standards, but annual re-calibration is customary. Calibration equipment is not required to zero gauge reference ranges. Absolute reference ranges may be zeroed with application of full vacuum. Span calibration should only be performed using appropriate calibration procedures with calibration standards that are at least four times more accurate than the gauge being calibrated. The calibration system must be able to generate and measure pressure/vacuum over the full range of the gauge. A vacuum pump able to produce a vacuum of 100 microns (0.1 torr or 100 millitorr) or lower is required for vacuum and absolute gauges. DPG1100AD, DPG1100ADBL Ranges above 2000 Entering Calibration Mode Remove the rear cover to gain access to the UP and DOWN buttons located near the lower right and left corners of the circuit board. Connect gauge to a 8-24 VAC 50/60 Hz or 9-32 VDC power supply. Allow the gauge to equalize to normal room temperature for approximately 20 minutes before calibration. Calibration of Ranges up to 1999 DOWN DPG1000, DPG1001 DPG1100 For DPG1000AD and DPG1100AD models remove the front covers to access the zero and span calibration potentiometers. For DPG1100AD models unscrew the nylon cover screws to access the zero and span calibration potentiometers. Gauges may be re-zeroed without affecting the span calibration. For gauge reference models the gauge port must be open to the ambient. For absolute reference models full vacuum must be applied. Adjust the zero control until the gauge reads zero with the minus (–) sign occasionally flashing. Zero calibration must be done before span calibration. Using the appropriate pressure standards, record readings at three to five points over the range of gauge and adjust span control to minimize error and meet specifications. UP With the gauge off, press and hold the DOWN calibration button, and also press the front button. The full-scale pressure range and display test is shown, and then CAL is displayed to indicate that the calibration mode is enabled. Release all buttons. The gauge enters and remains in the calibration mode until restarted manually or power is removed. Features not related to calibration are disabled. If the power is removed during calibration, settings will not be saved. The display will indicate the current pressure reading, updating approximately 3 times per second. Each press of the UP or DOWN button makes a small correction, which may not always be indicated on the display. Press and hold the button for one second or longer to make larger corrections. The gauge’s display is adjusted to match the calibrator’s reading. 3 Gauge Reference Ranges (3 Points) With the gauge port open to atmosphere, the character display will alternate between ZERO and CAL.
