Turn the Coarse knob to set the voltage to
4.00 V. Note that the displayed voltage
reflects the actual voltage at the output ter-
minals.
Turn the Fine knob. If you rotate it slowly,
the voltage changes by 0.01 V per detent. If
you rotate the knob more quickly, it changes
by 0.04 V per detent. Adjust the voltage back
to 4.00 V.

switch off the output. The Voltage LED
blinks rapidly, and the actual output voltage
drops to zero, though the display still shows

adjust the voltage setting while the actual
output remains zero. Return the voltage set-
ting to 4.00 V
Press
to switch the output back on. The
Voltage LED is now on steadily to indicate
