6. OPERATIONS PROCEDURES
– SINGLE TYPE
6-1 PRE-OPERATIONAL CHECKING
1. Visual inspection
First, the functional elements should be visually inspected for
damages. For example, the chassis, VR knobs, output terminals.
Function buttons, fuse holders, voltmeters, current meters, switches
etc. should be checked for visible damage.
If damage is detected, the supply should not be operated.
2. Basic electrical check
1) Check that the power switch is set to OFF.
2) Turn the voltage knob to maximum CCW, that is, minimum output
voltage.
3) If no problem is found for 1)~2), connect the supply's power cord to
the AC outlet and turn the power switch ON
4) Adjust the voltage setting knob to the desired voltage which can be
shown in the LCD display.
5) Connect the load, make sure the load current not exceeding the
maximum output current.
