Example: Set current at 1.000A.
Press [I SET][1][.][0][0][0][ENTER]
When the load current through output terminal exceeds
the setting value, the instrument is operated in the C.C.
mode, if not exceeds the setting value, the instrument is
operated in the C.V. mode.
5-2.Over Voltage /Current Protection Setting
At first, select the wanted channel by pressing [SHIFT][CHx] now
the cursor is set to CHx (x=1, 2 or 3).
--Over Voltage Protection Setting:
Method 1: Set OVP voltage level by pressing [OVP SET], and
using number key to key in [voltage value], then press
[ENTER].
Method 2: Press [OVP SET] and using knob to input [voltage
value], the OVP voltage level setting will be changed
immediately, then press [ENTER] to terminate the
OVP voltage level setting. Obviously, using this
method, the OVP voltage level will be changed
immediately following the input value through knob.
Example: Set OVP voltage at 33.00V.
Press [OVP SET][3][3][.][0][0][ENTER]
--OVP Status Clear Up:
When the output voltage exceeds 33.00V of the setting voltage,
the output of the instrument will be off and get into OVP mode by
displaying “Over Voltage Protection…” on the panel. Now press
[SHIFT][OVP RESET] to clear OVP status, back to previous
status.
--Over Current Protection Setting:
Turn on/off the OCP of each channel individually by pressing

Example：Set the step voltage of Channel 1 at 1.00V and the step
current at 0.10A.
Press [SHIFT][STEP], elect CH1 Voltage and input
[1][.][0][0][ENTER], then select CH1 Current and input
[0][.][1][0][0][ENTER]. Finally, using the knob to move the cursor
to [SAVE] and press [
ENTER] to complete the setting and storing.
