4) Set the desired output current value:
Press [I SET], the panel operation is set to current 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.
5) Start the output:
Press [OUTPUT] to enable output, now, the meter displays the
actual output measurement value.
6) Constant current mode confirmation
Check whether the C.C. indicator is on or not to make sure the
output operation is under the constant current mode. If the C.V.
indicator is on, it needs to enlarge its voltage limit value to assure
that the output operation is under constant current mode.
z Programming Over Voltage Protection, OVP
Set OVP level and the protection circuit of the OVP status.
1) Input the value of the Over Voltage protection limit value and set
the OVP status.
2) Confirm the function of OVP (Over Voltage Protection):
Adjust the output voltage up near to OVP level to confirm the
OVP function, when the OVP circuit is triggered, the OVP loop
will drop the output voltage near to zero, now, the OVP indicator
will be blinking.
3) Clear the OVP function:

Firstly, remove the external test unit, such as battery, from the
instrument, adjust the voltage down or raise up the OVP level,
then clear the OVP.
z Programming Over Current Protection, OCP
Set OCP level and the protection circuit of the OCP status.
1) Input the value of the Over Voltage protection limit value and set
the OCP status.
2) Confirm the function of OCP (Over Current Protection):
Adjust the output current up near to OCP level to confirm the
OCP function, when the OCP circuit is triggered, the OCP loop
will drop the output current near to zero, now, the OCP indicator
will be blinking.
3) Clear the OCP function:
Firstly, remove the external test unit, such as battery, from the
instrument, adjust the output current down or raise up the OCP
level, then clear the OCP.
z Storing and Recalling Operating:
1) The storing setting function including the store of the Output
range, Output voltage value, Output current value, Over Voltage
protection level, Over Current protection level, Over Voltage
protection status, Over Current protection status and the Delay
time.
