6) Turn on output.
Turn on the OUTPUT switch, and the output indicator lights and the power is output
through the output terminals.
Note : If it is not preferable to apply current suddenly like to a large inductance load, turn
the current adjuster knob (CURRENT) fully counterclockwise and increase current
gradually after turning on the output.
6-3. How to Check Voltage and Current
1) Voltage/Current presetting
When the V/I CHECK switch is depressed, the constant-voltage is indicated on the
voltmeter and constant current is indicated on the current meter.
Hereupon, it is possible to set a desired voltage or current with the voltage adjuster
knob (VOLTAGE) or current adjuster knob (CURRENT).
2) Voltage/Current check
When the V/I CHECK switch is depressed at constant-current operation, the preset
current and the preset voltage can be checked.
6-4. How to Set Overvoltage Protection (OVP) Level
Keeping the OVP CHECK switch depressed, the overvoltage protection level indicated on
the voltmeter.
1) Turn off the OUTPUT switch.
2) Keeping the OVP CHECK switch depressed, screw the OVP adjuster with a screwdriver
and set an overvoltage protection level.
3) Turn on the OUTPUT switch with no load connected (the indicator lights). Raising the
output voltage gradually, check if the power switch turns off at the preset overvoltage
protection level.
4) Set the overvoltage protection level at the maximum reading or the output voltmeter if
overvoltage protection is not necessary.
