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;
