Chapter 8. Calibration
3. Switch the instrument on, enter CALIBRATION mode and select EXT SENSORS from the
CALIBRATION menu:
4. Select the transducer to be calibrated from the transducer menu using the cursor keys and
press ENTER:
If the sensor to be calibrated is not in the directory, or no sensors are listed in the directory,
press the F1 key (ADD NEW SENSOR). This will place the sensor in the directory, allowing
it to then be selected.
5. Connect the pressure standard to the inlet of the external transducer, apply the zero point
pressure and store the zero point:
6. Apply the full-scale pressure to the external transducer and store the full-scale (FS) point
7. Release the applied pressure and disconnect the pressure reference. Press the ENTER key
to accept the calibration. Press the EXIT key once to return to the calibration menu or four
times to quit the CALIBRATION and SETUP modes.
8. Check the calibration of the external transducer by applying the test pressures as detailed in
Table 8.6 on page 40.
