① CC Mode:
The first line shows measured voltage and current levels. The second line shows current set level, CC
mode (CCH indicates constant current high range; CCL indicates constant current low range) and
input status of the load: (ON, OFF).
② CV Mode:
The first line shows measured voltage and current levels. The second line shows voltage set
level, CV mode, and input status of the load: (ON, OFF).
③ CR Mode:
The first line shows measured voltage and current levels. The second line shows resistance level, CR
mode (CRL indicates constant resistance low range; CRM indicates constant resistance medium range;
and CRH indicates constant resistance high range) and input status of the load: (ON, OFF).
