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 program in a 0 ... 2 bar pressure span into
the calibrator and the calibrator will then calculate and display the deviation or "%-Error" value from
GB
the 4 ... 20 mA output. This then eliminates manual calculations and also helps if it becomes
difficult to set an exact pressure with an external pump.
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) Use "SELECT" to scroll through the "UNIT" options, and select "NEXT" to move on.
5) Use the arrow keys to set the upper limit of the measuring range; select "DONE SET" when
finished.
