c) Press the front panel AC ON/OFF switch to the On position.
d) Turn On the output by pressing the OUT pushbutton (the front panel OUT LED
should illuminate).
e) Observe the Power Supply CURRENT display and rotate the CURRENT encoder.
Ensure that the Output current varies while the CURRENT encoder is rotated.
The minimum control range is from zero to the maximum rated Output current for
the Power Supply model. Compare the DVM reading with the front panel
CURRENT display to verify the accuracy of the CURRENT display. Ensure that
the front panel CURRENT LED is on.
f) Press the front panel AC ON/OFF switch to the Off position.
g) Remove the DVM and shunt from across the Power Supply output terminals.
3.8.5. OVP Check
Refer to Section 5.3 for explanation of the OVP function prior to performing the
procedure below.
a) Press the front panel AC ON/OFF power switch to the On position and turn on the
output by pressing the front panel OUT pushbutton.
b) Using the VOLT encoder, adjust the Output voltage to approximately 10% of the
unit Output voltage rating.
c) Momentarily press the OVP/UVL button so that the CURRENT display shows
"OUP". The VOLTAGE display will also show the last setting of the OVP level.
d) Rotate the VOLT encoder CCW to adjust the OVP setting to 50% of the unit
Output voltage rating.
e) Wait a few seconds until the VOLT display returns to show the actual Output
voltage.
f) Adjust the Output voltage toward its maximum and check that the Output voltage
cannot be increased more than OVP setting of Step d).
g) Adjust the OVP limit to the maximum value by repeating Step c) and rotating the
VOLT encoder clockwise (CW).
3.8.6. UVL Check
Refer to Section 5.4 for explanation of the UVL function prior to performing the
procedure below.
a) Press the OVP/UVL button TWICE so that the CURRENT display shows "UUL".
The VOLTAGE display will also show the last setting of the UVL level.
b) Rotate the VOLT encoder clockwise (CW) to adjust the UVL level to
approximately 10% of the unit Output voltage rating.
c) Wait a few seconds until the VOLT display returns to show the actual Output
voltage.
d) Adjust the Output voltage toward its minimum value and check that the Output
voltage cannot be decreased below the UVL setting of Step b).
e) Adjust the UVL limit to its minimum value by repeating Step a) and rotating the
VOLT encoder counterclockwise (CCW).
3.8.7. Foldback Check
Shorting the Output Positive and Negative connections together may
Refer to Section 5.5 for explanation of the FOLD function prior to performing the
