Example:
Suppose a pressure transmitter under test has a full scale range of 2
bar and gives a corresponding 4 ... 20 mA output signal. The user
can programme in a 0 ... 2 bar pressure span into the calibrator and
the calibrator will then calculate and display the deviation or %-Error
value from the 4 ... 20 mA output. This then eliminates manual
calculations.
To use the "%-ERROR" function, perform the following:
1. Once the calibrator is switched on and operating, press the F3
key to activate the "MORE" menu option. Then press the F1 key to
activate the "%-ERROR" option.
2. Press the F1 key to select the "CONFIG" option.
3. The first option is the port setting. Use the "SELECT" option to
scroll through the choice of ports (pressure connections). Once
this is completed, select the "NEXT" option.
4. "LOOP POWER" can be toggled on or off; select "NEXT" when
done.
