CALIBRATING THE ANALOG OUTPUTS

6.2.5
The analog outputs of the 9065 transmitter can be calibrated according to the following
procedure.

They can be set to any value from 0 mA to 20 mA, depending on the user's needs.

These values correspond to the values that are set for the analog outputs.

The default settings are 4 mA and 20 mA.
Procedure:
1. In the main measurement screen, press the Enter button for longer than 3 seconds. The
main menu will be displayed.
2. Use the cursor keys to select 'Configuration' and press the Enter button to confirm the
selection. (Note: the Calibration menu is level B Supervisor Level.)
3. Use the cursor keys to select 'Analog outputs' and press the Enter button to confirm the
selection.
4. Use the cursor keys to select 'Calibrate analog outputs' and press the Enter button to
confirm the selection.
5. In this screen, the analog outputs can be calibrated to the
correct mA value. A milliammeter (or a multimeter) must
be connected to the appropriate output to measure the
flow through the output.
6. When selecting 'MIN. mA value', the corresponding
analog output will cut out. The value can be increased
or decreased using the cursor keys. The count value
will increase or decrease as the flow rate is increased or
decreased. This is how the output is calibrated.
7. When selecting 'Max. mA value', the corresponding
analog output will cut out. The value can be increased
or decreased using the cursor keys. The count value
will increase or decrease as the flow rate is increased
or decreased. This is how the output is calibrated.
8. After the outputs have been calibrated, select 'Store
calibration' to save the settings in the 9065 memory. Select the Return option to return to
the previous menu.
NOTE:
39
The calibration data for the previous calibration will be kept
if you return to the previous menu without selecting 'Store
calibration.'
