Omega DPG5000 manual Instructions Zero Trimming, Use of Auto-Tare Feature

DPG5000 M3366/0606

• Instructions

NOTE: All units are factory calibrated prior to shipment.

1. Zero Trimming

NOTE: Some units are equipped with zero “knob”.

If it becomes necessary to re-adjust the “Zero” on the display, this can be accomplished by turning the trimpot marked “Z” just to the left of the On/Off push button. On the DPG5000 there is either a zero adjustment knob or a black nylon cover screw. If the gauge has a cover screw, it is necessary to remove the cover screw to access the zero adjustment pot. An ideal zero is indicated by a reading of 000 with an intermittently flashing “-” sign.

NOTE: A jewelers screwdriver or an eyeglass repair screwdriver (supplied) is a suitable instrument. Do not make changes to the Span adjustment (the “S” pot to the right of the push button) as part of the zero trimming. The Span should only be changed as part of the re-calibration of a gauge with a known pressure source.

2. Use of Auto-Tare Feature

When the DPG5000 is first turned on you will notice that the display flashes for the first 4 seconds. If the On/Off button is pushed and held during this period, any existing reading will be re-set to zero. This allows the user to “Tare- Out” a starting weight in hydraulic weighing applications. To remove the Tare feature turn the unit off and back on again and do not push the On/Off button during the flashing period.

3. Battery Replacement (9 Volt Type)

The battery can be replaced simply by removing the single screw at the top of the battery door. Remove the old battery, unplug the cable connector and replace with Eveready type 216 or equivalent. Replace the battery door and secure with the self-tapping screw. (Do not overtighten)

NOTE: For best accuracy, re-calibration per step 4 should be performed at the time batteries are replaced.
