Fine adjustment function
This function increases the resolution of the VOLTAGE and CURRENT knobs. By
turning the VOLTAGE or CURRENT knob while holding down the SHIFT key,
you can set the value using finer resolution.
The display resolution of the preset voltage and preset current does not change even
if you use the fine adjustment function. Therefore, the displayed value may not
change even if you turn the knob. The display changes when the amount of change
reaches the minimum displayed digit of the preset voltage or current.

•
The ALARM LED on the front panel display illuminates, then the cause of alarm
occurrence and the current measuring value displays alternately.
When the breaker trip is selected in overvoltage protection (OVP) or overcurrent
