In show area the [DISP. MEAS.] and [DISP. JUDG.] are fast keys, press these two keys will
directly enter the measurement screen, after modify one of the test can easy enter test screen,
[DISP. MEAS.] is to show measurement screen, [DISP. JUDG.] is to show judgment result
screen.
Example:
Input parameter setting:
There are spec. and unknown parameter of one transformer as following:
