In the analog output adjustment mode, you can
test the output level of the transmitter with a multimeter, and adjust the output level
(2-point adjustment) if necessary.
Note: Always switch the adjustment mode
off after testing to return the analog output to normal operating mode. Normal measurement
data output is not available in adjustment mode.
To test and adjust the analog output level of
this channel:
- Connect the multimeter to the analog output
2 screw terminals on the transmitter component board.
Enable the adjustment mode with the
Adjustment mode on/off selection.
Start the low point output test with the
Output low point button. The analog channel starts to send the low point test output.
You can follow the output level and
stabilization from the output level graph.
- 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.
- Start the high point output test with the
Output high point button. The analog channel starts to send the high point test output.
- 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.
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.
- 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.
- Disable the adjustment mode with the
Adjustment mode on/off selection and select Close to exit the calibration mode.
