Example:
Suppose a pressure transmitter under test is 30 psi (2 Bar) Full Scale and outputs a corresponding 4
to 20 mA signal. The user can program in a 0 to 30 psi pressure span into the calibrator and the
calibrator will calculate and display the deviation or % Error from the expected 4 to 20 mA output.
This eliminates the need for manual calculations and also helps if it becomes difficult to set an exact
pressure with an external pump.
To use the %ERROR function proceed as follows:
. With the calibrator turned on and operating press the F3 key to activate the MORE
menu option. Now press the F key to activate the %ERROR option.
2. Press the F key to select the CONFIG option.
3. The first option is setting the Port, use the select option to scroll through the port
choices, when finished select the NEXT option.
4. LOOP POWER can be toggled on/off, select NEXT when done.
5. Use SELECT to toggle through the UNIT options, and select NEXT to move on.
