Current and voltage test output points Fixed test output level
Low point test output for voltage output 1 V
High point test output for voltage output 10 V
Always switch the Insight analog output adjustment mode o after
testing or adjusting to return the output to normal operating mode. Normal
measurement data output is not available in the adjustment mode.
CAUTION!
7.2.4.1 Analog output adjustment example
Always switch o the transmitter power supply when connecting or
disconnecting screw terminal wiring. Do not energize the transmitter power
supply when wiring is not connected.
CAUTION!
Always switch the Insight analog output adjustment mode o after
testing or adjusting to return the output to normal operating mode. Normal
measurement data output is not available in the adjustment mode.
CAUTION!
To test and adjust the voltage output level of the transmitter's analog output 1 with Insight:
1. Switch o the transmitter power supply and open the transmitter cover.
2. Connect the multimeter wiring to analog output 1 screw terminals and close the
transmitter cover.
3. Power on the transmitter and connect the transmitter to the Insight PC software.
4. To open the calibration menu, select
to access Insight main menu. In the main menu,
select Calibrate.
5. Select Analog output 1 and enable the adjustment mode with the Adjustment mode on/
o selection.
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 oset and High point oset fields.
