0 to 82°C 2 DPG1000B, DPG1001B, DPG1000BBL, DPG1100B, DPG1100BBL CAUTION: 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. Permanent 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. NOTE: 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! 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. If the gauge was ordered without auto shutoff (NS) 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. Display backlighting on BBL models is on whenever the gauge is on. Backlighting may not be apparent under bright lighting conditions. 1000B,1001B,1000BBL Operation – Ranges 2000 and up including 3000 psi, 5000 psi These ranges have a 4-digit display with a lower alphanumeric display. 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. 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 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 o ooo ooo ooo oois 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. Normal Operation – Ranges 2000 and up including 3000 psi, 5000 psi Following the start-up initialization, the display indicates the pressure reading updated approximately 3 times per second and the units. 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 (-NS option). 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. Display Backlighting (BBL models only) – Ranges 2000 and up including 3000 psi, 5000 psi Display backlighting can be turned on by momentarily pressing the button whenever the gauge is on. The backlighting will turn on for one minute and then automatically shut off. This also restarts the auto shutoff timer. Backlighting may not be apparent under bright lighting conditions. Shut-Down – Ranges 2000 and up including 3000 psi, 5000 psi To shut off the gauge manually at any time, press and hold the pushbutton until the display indicates OFF and then release. For gauges with auto shutoff, the display indicates OFF five seconds prior to auto shutoff. The pushbutton can be pressed to keep the gauge on. The auto shutoff and backlight (if equipped) timers are reset whenever the pushbutton is pressed and released. If the gauge was ordered without auto shutoff (NS option) it will stay on until manually shut off or until the batte...
