5. Output status/ mode
OFF: output is off;
CV: Constant voltage mode: The output voltage is equal to the set voltage value. The
output current value is equal to the voltage setting value divided by the load resistance
value. If the load current exceeds the set current value, it will change to constant current
mode.
CC: Constant current mode: the output current is equal to the set current value. The
output voltage value is equal to the current setting value multiplied by the load resistance
value. If the load voltage exceeds the set voltage value, it will become a constant voltage
mode.
OV: Overvoltage protection;
OC: Overcurrent protection;
OT: Over temperature protection;

LT: Low temperature protection. The sensor is lower than -10℃, which may be due to
environmental problems too low, or the sensor is damaged. So channels are forbidden to
output. When the hardware restored to normal, this phenomenon is eliminated.
MV: If voltage out of control, it may be the adjustment tube is damaged. So channels
are forbidden to output. After reset and restart, this phenomenon is eliminated.
LE: May be that the 220V supply voltage inputs to the device of the 110V input
configuration, in which case the channels is forbidden to output. When the hardware
restored to normal, this phenomenon is eliminated.

Chapter 2 Getting Started
This chapter introduces the items that users need to pay attention to when starting to use
this series of programmable DC power supplies in order to carry out subsequent operations
smoothly.
1. Check the AC voltage range
This series of programmable DC power supplies support various specifications of AC
power input, and users can choose the appropriate input gear according to actual needs.
The user must check the gear position of the AC voltage selector on the rear panel of the
power supply before using it, and the input voltage must be within the allowable range
(±10%) of the gear position. The corresponding relationship between the voltage selector
on the rear panel of the power supply and the allowable input voltage is as follows:
2. Check the fuse
The instrument has been installed with the specified fuse at the factory. Before use, please
check whether the fuse type matches the AC voltage range. If it does not match or the fuse
is blown, replace the fuse according to the specifications.
Steps to replace the fuse:
1. Turn off the power and unplug the power cord;
2. Lift out the fuse holder;
3. Remove the broken fuse and install a new one;
4. Put the fuse holder back into the slot.
