TEST is ON, and the LED, GO/NG, is lighted on the panel. To set specifications for the load;
please refer to the section 3.5 at the end of each mode for parameters setting. The
specification unit for CC, CR, and CP modes is volt while CV mode is current. There are
three levels for each mode: CENTER, HIGH and LOW. The CENTER level must be set by
the value of channel input reference level. The HIGH and LOW levels can be set by the
value or percentage selected in configuration SPEC.ENTRY MODE. The HIGH/LOW
percentage range is from 0 to 100%.
The default setting of HIGH and LOW is 100%. The CENTER value is half of the range.
