5.Front Panel Operation

(1) Press the orange Volt/CV or Curr/CC key, the input box of Negative output
voltage/current will pop up.
(2) The operation of input box is the same as Independent mode.
In the same way, press the blue Volt/CV or Curr/CC key to set the Positive output
voltage/current.
Note: If the input value is out of the rated range, the box prompts "ERROR"; you need to
input another value within the rated range.
In Series mode, the minimum rating of the current is 0.1A; in other modes is 0.02A.
5.3 Over Voltage/Current Protection
When the Over Voltage Protection (O.V.P) or Over Current Protection (O.C.P) is enabled,
once the output voltage/current reaches the set value of O.V.P/O.C.P, the instrument will
cut off the output. The value of O.V.P/O.C.P which causes cutting off will turn red and
flashing; the instrument will make a buzzing sound if the buzzer is turned on.
Note:
When the instrument disables the output due to protection, after you make some
adjustments, the channel must be restarted to output normally.
This function can keep the power output from exceeding the load rating in order to protect
the load. The O.V.P/O.C.P can be set separately for the four working mode and for
different status (normal, timer). You can enable or disable these functions as required.
The parameters of the O.V.P/O.C.P set in normal status take effect in normal status. The
parameters of the O.V.P/O.C.P set in timer status take effect in timer status.
Note:
In Plus-minus mode, if either of the Positive or Negative output voltage/current reaches its
own O.V.P/O.C.P, the instrument will disable the output.
5.3.1 Set O.V.P
(1) Enter the O.V.P setting menu:
 Independent Mode
Press the System key, enter [System
→ CH1 (CH2) → O.V.P].
 Parallel, Series Mode
Press the System key, in normal status, enter [System
→ O.V.P];
in timer status, enter [System
→ Pro Set → O.V.P].
 Plus-minus Mode
Press the System key, enter [System
→ Positive (Negative) → O.V.P].
(2) A setting box pops up, press the
▲ / ▼ key to switch the state of the O.V.P between
