Introduction

The DPI 832 Electrical Loop Calibrator is part of the Druck DPI 800 series of hand held instruments. The DPI 800 series uses Intelligent Digital Output Sensor (IDOS) technology to give instant plug and play functionality with a range of Universal Measurement Modules (UMM). Example: the Universal Pressure Module (UPM). The DPI 832 includes these functions:
Function
* Measure dc mA, mV, Volts * Supply dc mA, mV, Volts Step/Ramp functions: Automatic/Manual Communications port: IDOS or RS232 Language selection ** Measure press ure/Leak test: External IDOS UPM ** Snapshot: Up to 1000 displays with a date/time stamp HART® resistor Switch test Other functions: Hold, Maximum/Minimum/Average, Filter, Tare, Scaled values, Backlight, Alarm
* Refer to “Specification data”. ** Optional item

Safety

Before you use the instrument, make sure that you read and understand all the related data. This includes: all local safety procedures, the instructions for the UMM (if applicable), and this publication.
WARNING
• It is dangerous to ignore the specified limits for the instrument or to use the instrument when it is not in its normal condition. Use the applicable protection and obey all safety precautions.
• Do not use the instrument in loca tions with explosive gas, vapor or dust. There is a risk of an explosion.
• To prevent electrical shocks or damage to the instrument, do not connect more than 30V between the terminals, or between the terminals and the ground (earth).
• UPM only. To prevent a dangerous release of pressure, isolate and bleed the system before you disconnect a pressure connection.

) to set a value less than the switch
value.
b. Use the ▲ ▼ buttons to change the value in small
increments.
•Example - “Ramp” output. a. Set “High” and “Low” values that are applicable to
the switch value (Table 6). Then, to get an accurate switch value, set a long “Travel” period.
b. Use Start/Stop (
) to start and stop the “Ramp”
cycle.
4. If necessary, supply the output values in the opposite direction until the switch changes condition again.
The display shows the applicable values to open and close the switch.
5. To do the test again, press ESC to reset the values.

Operation - UPM Pressure measurements

Read all the instructions supplied with the UPM and then use the specified procedures to connect it (Figure 6/7).

a) Pressur e b) Leak test
Start Settings
Figure 6: Example configuration - Pressure measurement
with a UPM
When the connections are complete, make the necessary IDOS selections (Table 2/3). 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.

UPM - Measure the pressure

To measure the pressure (Figure 6):
1. Select the applicable pressure task from Select Task (Table 2/3) and, if necessary, adjust the Set Up (Table 1), and the Settings (Table 4/5).
2. If necessary, do a zero correction (Table 4).
To measure pressure with another operation (Figure 7), use the same procedure.

To do a leak test on a pressure system (Figure 6):
1. Select an applicable leak test from Select Task (Table 2/3) and, if necessary, adjust the Set Up (Table 1), and the Settings (Table 4).
2. Set the period for the leak test (Table 4).
3. If necessary, do a zero correction (Table 4).
4. To start the leak test, select Start (
). When the test is
finished, the instrument calculates the leak rate in the applicable units/minute.

Operation - 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.

Maintenance

This section gives procedures to maintain the unit in a good condition. Return the instrument to the supplier for all repairs.

Maintenance – Clean the unit

Clean the case with a moist, lint-free cloth and a weak detergent. Do not use solvents or abrasive materials.

Maintenance – Replace the batteries

B1
To replace the batteries, refer to 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.

Calibration

Note: GE 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 a n alternative calibrat ion facility, make sure that it uses these standards.

Calibration - Before you start

To do an accurate calibration, you must have:
• the calibration equipment specified in Table 8.
• a stable temperature environment: 70 ± 2°F (21 ± 1°C)

Calibration - Procedures (mA output)

1. Connect the instrument to the calibration equipment (Figure 3).
2. Let the equipment get to a stable temperature (minimum: 5 minutes since the last power on).
3. Use the calibration menu (Table 9) to do a two-point calibration (Zero and +FS). The display shows the applicable instructions to complete the calibration.
4. To make sure that the calibration is correct, select the applicable mA output task (Table 2) and set these output values:
• mA: 0 (short circuit), 4, 12, 20, 24
5. Make sure that the error is in the specified limits (Table 15).

Calibration - Procedures (IDOS UMM)

Refer to the user manual for the IDOS UMM. When the calibration is complete, the instrument automatically sets a new calibration date in the UMM.
