PAD-L Basic Operation 3-5
5. Use the VOLTAGE setting knob to set a value for overvoltage to protect
the unit.
6. Slowly turn the O.V.P variable resistor counterclockwise and stop it
when the POWER switch turns off.
7. Turn the VOLTAGE setting knob counterclockwise to lower the output
set voltage.
8. Wait approximately 60 seconds, then turn on the POWER switch.
9. Slowly turn the VOLTAGE setting knob clockwise and check that the
POWER switch is turned OFF when the output voltage reaches the set
OVP voltage.
10. Turn the VOLTAGE setting knob counterclockwise to lower the output
set voltage.
OVP trip point presetting for TYPE V model
CAUTION
• The OVP trip point of the TYPE V model can be preset without
outputting an actual voltage. However, to ensure safety, always
check that the OVP trips at the set voltage after setting the OVP
trip point.
To check that the OVP trips, an actual voltage must be output;
disconnect any load that may be connected.
1. Check that nothing is connected to the unit output terminals.
2. Use a slotted head screwdriver to turn the O.V.P variable resistor to the
extreme clockwise position.
3. Turn the CURRENT setting knob clockwise.
Turning it slightly is sufficient, since no current flows at no load.
4. Turn the VOLTAGE setting knob counterclockwise.
5. Turn on the POWER switch.
6. Turn the O.V.P variable resistor while holding down the O.V.P PRESET
switch to set a value for overvoltage to protect the unit.
7. Slowly turn the VOLTAGE setting knob clockwise and check that the
POWER switch is turned OFF when the output voltage reaches the set
OVP voltage.
8. Turn the VOLTAGE setting knob counterclockwise to lower the output
set voltage.
