Check

1. Ensure that the front panel voltage and current control are turned fully

counter-clockwise.

2. Set the power switch to ON.
3. Rotate the current control one half-turn clockwise. Slowly rotate the voltage

control clockwise and observe the digital meter. Minimum control range should
be from zero to maximum rated output. Observe the bar graph meter to see that
it tracks as the voltage rises. Verify that the voltage mode indicator light is ON.
