6. Start the low point output test with the
Output low point
button. The analog channel
starts to send the low point test output (1 V in this example).
7. After the low point test output has stabilized, check the multimeter reading. Enter the
reading of the multimeter in the
Measured value, low point
field.
8. Start the high point output test with the
Output high point
button. The analog channel
starts to send the high point test output (10 V in this example).
9. After the high point test output has stabilized, check the multimeter reading. Enter the
reading of the multimeter in the
Measured value, high point
field.
10. Select
Activate adjustment
to save the corrections to the output level.
The corrections are shown in the
Low point offset
and
High point offset
fields.
11. To verify that the output level of the transmitter is now accurate, repeat the low point and
high point output tests and check that the multimeter reading matches the test output.
The adjustment date and information about the adjustment can be entered in the
Calibration date
and
Calibration text
fields.
12. Disable the adjustment mode with the
Adjustment mode on/off
selection and select
Close
to exit the calibration mode.
13. Switch off the power supply, remove the multimeter wiring and replace the analog output
