Prepare Information
Before doing performance verification, you should master the following
operations to make the power work in a good state or deal with some simple
functional problems. The following contents are included in this chapter:
⚫How to perform functional checks
⚫How to test the interface working properly
For more detailed information about the SPS’s operation, please refer to the
Quick Guide for the SPS5000X.
Power-on Inspection
Verify that the power supply is working properly by performing a power-on check.
The power supply voltage of the SPS5000X series is 100 VAC to 240 VAC.
Please select a suitable power cord to connect to the socket on the rear panel
of the power supply.
Note: to avoid electric shock, make sure that the instrument is correctly
grounded to the earth before connecting AC power.
