Measurement with a UPM
When the connections are complete, make the necessary
IDOS selections (Table 2 & Table 3). Then use the same
procedures as specified for the P1/P2 connections.
If you re-attach a UPM, the instrument uses the same
measurement units that you used before. The instrument
keeps a record for the last 10 modules.

2.9 Error Indications
If the display shows <<<< or >>>>:
• Make sure that the range is correct.
• Make sure that all the related equipment and
connections are serviceable.
3. Maintenance
This section gives procedures to maintain the unit in a good
condition. Return the instrument to the manufacturer or an
approved service agent for all repairs.
3.1 Clean the Unit

3.2 Replace the Batteries
To replace the batteries, refer to Figure B1. Then re-attach
the cover.
Make sure that the time and date are correct. The
calibration facility uses the date to give service and
calibration messages.
All the other configuration options stay in memory.
3.3 Return Goods/Material Procedure
If the unit requires calibration or is unserviceable, return it
to the nearest Druck Service Centre listed at:
https://druck.com/service.
Contact the Service Department to obtain a Return
Goods/Material Authorization (RGA or RMA). Provide the
following information for a RGA or RMA:
• Product (e.g. DPI802)
• Serial number.
• Details of defect/work to be undertaken.
• Calibration traceability requirements.
• Operating conditions.
4. Calibration
Note: Druck can provide a calibration service that is
traceable to international standards.
We recommend that you return the instrument to the
manufacturer or an approved service agent for calibration.
If you use an alternative calibration facility, make sure that
it uses these standards.
4.1 Before You Start
To do an accurate calibration, you must have:
• The calibration equipment specified in Table 5.
• A stable temperature environment: 70 ± 2°F (21 ± 1°C)
Table 5: Calibration Equipment
Function
Pressure
mA
Before you start the calibration, make sure that the time
and date on the instrument are correct (Table 1).
Calibration Equipment
An applicable pressure standard (primary or
secondary) with a total uncertainty of 0.01%
reading or better.
mA calibrator.
Accuracy: Refer to Table 8.
