SECTION 4: ELECTRICAL SET-UP / OPERATIONAL NOTES
Place the test set in the desired location. Divider base must be at ground level. High voltage
should enter divider from above at an angle of no greater than forty-five degrees from
vertical for highest accuracy readings.
Connect a ground of sufficient size from the source ground to the grounding post located at
the base of the divider. (A 10’ lead is supplied with the unit.)
CAUTION: The ground post on the divider base must be connected to the ground or
damage to the unit may result.
Connect the supplied coaxial cable between the low voltage arm located at the base of the
divider and the metering module. (A 25’ lead is supplied with the unit.)
NOTE: The coaxial lead is part of the calibration. Significantly changing the length of the meter
lead will affect the AC calibration.
CAUTION: The meter module has to be grounded for safe and proper operation.
Connect the ground post on the metering module to an appropriate ground (A 10’ lead is
supplied with the unit).
CAUTION: A ground should always be connected to the ground post on the metering
module.
Connect the source voltage to be measured to the top of the divider by an appropriate and
safe method.
CAUTION: Meter low range should not be used past 30kV. Meter may not be accurate past
100% of reading and actual voltage may be much higher than indicated.
Note: Unit is designed to measure voltage in reference to ground. Source voltage
and divider ground post must be ground referenced for unit to operate
properly.
WARNING
:
THIS UNIT SHOULD ONLY BE OPERATED BY PERSONS KNOWLEDGEABLE OF HIGH
VOLTAGE TESTING AND SAFETY PROCEDURES. IMPROPER OPERATION MAY
RESULT IN INJURY OR DEATH.
ENSURE THAT UNIT TO BE TESTED IS DE-ENERGIZED AND DISCHARGED! ENSURE
THAT WORKING ENVIRONMENT IS SAFE AND FREE OF HAZARDS.
