Page 6: Instructions
DPG10L • Instructions The model DPG10L Digital Pressure Gauge has several features not normally found as standard in Digital Pressure Gauges. These include the Analog Scale, Tare, and Peak Holds. The Analog Scale is a 40 segment display that appears around the edge of the liquid crystal display. This scale represents the pressure reading as a percentage of full scale, and each individual segment equals 2.5%. The Tare feature provides a method of zeroing out an existing offset such as the weight of the platform on a hydraulic scale. The Hold feature allows the user to select Hi or Lo. When the Hold is enabled the reading displayed is the highest or lowest pressure experienced in the system since Hold was enabled, and this information will continue to be updated at the rate of six times a second until Hold is disabled. 1.0 To Zero or “TARE OUT” an existing offset 1.1 Press and hold the “MODE” key until the reading starts flashing. Release “MODE” key. 1.2 Press “ENTR” key until the reading becomes 0000. NOTE:.Tare.range.is.100%.of.Full.Scale. 1.3 To return to the Gross reading press and hold “ENTR”, then with “ENTR” still depressed press “MODE” until the reading returns to the gross, then release both keys. 2.0 To select PEAK HI or PEAK LO hold functions 2.1... -
Page 7: To.set.alarms
3.0 To Set Alarms 3.1 Press and hold the “MODE” key until the reading starts flashing, then Press the “MODE” key twice more. The display will read “AL 1”. Press the “ENTR” key to display the alarm setting. Pressing the “ENTR” key again will set the alarm and return the display to the normal mode. If the alarm setting is to be changed, the “up” and “down” keys can be used to increase or decrease the setting one count at a time, Pressing the “MODE” key and holding it down while Pressing “up” or “down” momentarily will change 10 counts for each key operation. If the “MODE” key and “up” or “down” are held down simultaneously, the setting will ‘FREE RUN’ until the key is released. NOTE:.While.setting.the.alarm,.only.one.segment.of.the.analog.scale.is. displayed.and.it.corresponds.to.the.%.full.scale.of.the.alarm.setting. 3.2 When the desired alarm setting is displayed, Press “ENTR” to set and return to normal mode. 3.3 To set alarm 2: Press and hold the “MODE” key until the reading starts flashing, then Press the “MODE” key three more times. The display will read “AL 2”. Press “ENTR” key to display the alarm setting. Pressing the “ENTR” key again will set the alarm and return the display to the normal mode. If the alarm setting is to be changed, the “up” and “down” keys can be used to increase or decrease the setting one count at a time, Pressing the “MODE” key and holding it down while Pressing “up” or “down” momentarily will change 10 counts for each key operation.

Page 8: Zero.trimming
DPG10L 3.5 The alarm set point indicator segment of the bar graph will “blink” when that set point is activated. The hookup of optional outputs is covered later in this manual 4.0 Zero Trimming 4.1 Should it be necessary to readjust the Zero setting, an adjustment has been provided. Prior to adjusting the zero, verify that you are displaying the “gross” zero reading by performing step 1.3. On the back of the case, in the upper left, there are two cover screws labeled “Z” and “S”. Remove the screw covering the “Z” and utilizing a jewelers screwdriver, turn the small screw to re-zero the unit. The ideal zero is indicated by a reading of 0000 with an intermittently flashing “-” sign. NOTE:.Do.not.readjust.the.“S”.as.this.will.invalidate.the.factory. calibration. 5.0 Re-calibration This procedure requires a known pressure source of at least ± 0.1% accuracy in order to fully utilize the potential of the DPG10L (If not available, the gauge may be returned to OMEGA for re-certification) 5.1 With 0 psig applied (port vented) adjust zero per instructions of 4.0. 5.2 Apply full scale pressure to the pressure port and adjust the “S” until the display reads the correct pressure. 5.3 Re-check zero and re-adjust the zero if required. 5.4 Repeat steps 5.2 and 5.3 until no further adjustment is required. 6.0 Battery Replacement 6.1 To access the battery, the unit must be partially disassembled. Remove the thread ring surrounding the lens by turning counter clockwise. Carefully turn the unit face down with one hand prepared to “catch” the lens and display board as they fall from the housing. Do not allow the display board to fall more than an inch or two as there are wires connecting it to the main housing. -
