Calibrating Transmitters; Using The Ma Measurement Function - WIKA CPH65I0 Betriebsanleitung

6. Commissioning, operation
8. Select the "NEXT" option to display the pressure at which the switch closed and the
hysteresis "SW DEADBAND" .
9. Select the "NEW TEST" option to clear the data and perform another test.
10. Select the "DONE" option to end the test and return to the standard pressure
setting.
The previous example uses a normally closed switch. The basic
procedure is effectively the same for a normally open switch, the display
will simply read "OPEN" instead of "CLOSE".

6.11.1 Using the mA measurement function

WARNING!
Observe the connection parameters prior to making a connection to the
instrument.
The mA function enables to read out the 4 ... 20 mA output from the instrument being
calibrated. This is achieved passively - meaning the test item generates the 4 ... 20 mA
directly. This value is read by the calibrator.
