5-3. Operation Method

The applied Voltage/Current Unit for this series instruments is Volt and

Amp.

Constant Voltage Operation

1) Connect load to output terminal:

For the safety, when connect the load to output terminals of (+)

and (-), it must turn off the power.

2) Select output range:

Turn on the power after the load is well connected, select the

adequate operation range by pressing [SHIFT][8V/20A] or

[SHIFT][20V/10A]).

3) Set the current limit value:

Press [I SET], the panel operation is set to current value input

mode, set the desired change value by using the number key or

the wheel knobs (the wheel knob can be used together with [<] or

[>] to adjust the resolution).

4) Set the desired output voltage value:

Press [V SET], the panel operation is set to voltage value input

mode, change to the desired value by using the number key or the

wheel knobs (the wheel knob can be used together with [<] or [>]

to adjust the resolution).

Press [OUTPUT] to enable output, now, the meter displays the

actual output measurement value.

6) Constant voltage mode confirmation

Check whether the C.V. indicator is on or not to make sure the

output operation is under the constant voltage mode. If the C.C.

indicator is on, it needs to enlarge its current limit value to assure

that the output operation is under constant voltage mode.
