4. Click Read, to see the effects of your modification.
5. Click Service/Calibration Performed to reset the schedule.
7.1.6.8 Select analog output
Allows you to set the mA Output to report Level, Distance, Space, or Volume. See Current
Output Function (2.6.1.) for an illustration.
If a volume application is selected, mA Output is automatically set to Volume. See Analog
Output (Page 230) for more details.
1. Open the menu Device – Select Analog Output.
2. Select Analog Output window displays the current setting: click OK.
3. Select a different setting and click OK.
4. Select Analog Output window displays the new setting: click OK.
7.1.6.9 Self test
Checks memory (RAM and Flash). If there are no errors, returns the message 'Self Test OK.'
If errors are found, returns the message 'Self Test Fails'.
Open the menu Device – Self Test, select Yes and click OK.
7.1.6.10 Loop test
Note
The simulated AO (Analog Output) value influences output to the control system.
Allows you to input a simulated value (4 mA, 20 mA, or a user-defined value) in order to test the
functioning of the mA connections during commissioning or maintenance of the device. The
range is 3.56 mA to 22.6 mA, see mA Output Value (2.6.6.).
To simulate a user-defined mA value:
1. Open the menu Device – Loop Test.
2. Select Other, enter the new value, and click on OK. The message ’Field Device fixed at [new
value]’ appears. Click on OK. The Loop Test window remains open.
3. When you are ready to end simulation, select End and click on OK to return the device to the
actual output value.
7.1.6.11 Configuration flag reset
To reset the configuration flag to zero, open the menu Device – Configuration Flag Reset and
perform a reset.
