plugged into the tester. Also verify the location
of the positive (red) and negative (black)
Voltage Output Test Points, which are used to
measure the output voltage.
1.
Plug in the power cord. Adjust the
front panel VOLTAGE knob fully
counterclockwise to the minimum position.
Turn the rear-panel power switch ON. The
CHARGE indicator should be lit.
2. Toggle the POLARITY switch from
NOR to REV . Adjust R6 so that the
voltage reading on the front panel LED
display is as close to zero in both
NOR and
REV positions. Note that the display may
read some residual voltage of
approximately 10 volts.
3. Connect a suitable DC voltage meter to
the Voltage Output Test Points. The red
test point is positive; the black test point is
negative.
4. Press the CHARGE button. Use the
VOLTAGE adjustment knob to increase
the output voltage to near the maximum
rated peak output voltage of the MegaPulse
tester.
5. Using a non-conductive screwdriver,
adjust R7 so that the voltage reading on the
front panel LED display agrees with the
voltage reading on the DC voltage meter.
6. Turn the VOLTAGE adjust knob back
down to zero. Allow the output voltage to
decay down to a safe level (this may take a
few minutes). Remove the DC voltage
meter leads.
7. Turn the rear-panel power switch OFF,
and replace the top cover of the
MegaPulse tester.
If the results of the calibration procedure are not
in accordance with the above, service is
required. Remove the Tester from service and
contact the manufacturer for servicing
information. If the results of the tests above are
correct, the tester may be put back into use.
