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.
