Note:
If a PC connected to the IED using the rear communications port is being used to display the measured current, the process
will be similar. However, the setting of the Remote Values cell in the MEASURE'T SETUP column will determine whether the
displayed values are in primary or secondary Amperes.
The measurement accuracy of the IED is +/- 1%. However, an additional allowance must be made for the accuracy
of the test equipment being used.
