Manual calibration
First enter the parameter setting menu, input the calibration constant, the number of calibration turns, CT ratio (such as 200/5). Select the active meter (or reactive meter), select the manual input mode, connect the manual switch plug to the measured input of the detector, and the black mark with the meter turntable is out of date, press the manual switch, and the timing starts. When the black mark is rotated by the corresponding number of turns for the corresponding number of times, press the manual switch to complete the timing and automatically display the error of the device under test.
When using the photo head or the check pulse meter, the input mode can select the pulse, and the other settings are the same as the manual calibration.
