SECTION 3: UNCRATING/MECHANICAL SET-UP
Exercise care in removing shipping materials so as not to damage the unit.
Perform a visual inspection to determine if the unit was damaged in shipment. If there are any
signs of physical damage such as dents, scratches, or oil leaks, contact the factory before
proceeding.
NOTE
Read and understand all setup and operating instructions before use of the unit. Failure
to do so may cause damage to the unit and possibly void the warranty.

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.

SECTION 5: OPERATING INSTRUCTIONS
1) DIVIDER WITH METER MODULE OPERATION:
Make sure connections have been made as described in “Set-Up” section.
Switch control power switch to ON position.
Select the desired range for the voltmeter based on the expected input signal level.
Select desired mode for voltmeter with function switch.
Note: If the Ripple voltage measurement mode is to be selected, the Range selector must
be set for the required input voltage level. If ripple voltage is to be read on input
voltage over 30kV the range selector has to be on high range, regardless of the
expected ripple voltage level. To avoid damage to the unit ascertain the unit will
not over-range on the AVG or the DC modes before attempting to read the ripple
voltages. DO NOT attempt to read ripple voltage on a range lower than required to
measure the full input voltage.
Activate high voltage source.
Measure voltage as required. 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.
De-activate high voltage source and assure, as appropriate, that high voltage source is de-
energized and discharged.
When testing is complete, switch control power to OFF position.
After assuring that high voltage source and unit are de-energized and discharged, all leads
and connections may be disconnected and unit packaged for transport or storage.
Do not subject unit to Flashovers. Damage may occur. If meter becomes disabled from
Flashover or Transient condition, refer to Troubleshooting section.
Battery operational time will be extended if Backlight is kept at minimum setting.
Low battery lamp comes on at approximately 20% of charge. If unit is run too long after low
battery lamp comes on, it will shut down and must be recharged before it will turn on again.
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.

OPERATING INSTRUCTIONS
2) STAND ALONE DIVIDER OPERATION:
Make sure connections have been made as described in “Set-Up” section, except that the
meter module will not be used or connected.
Connect a Voltmeter to the BNC output on the base of the divider with the 25’ coaxial cable.
NOTE: The divider has approximately 10,000 to 1 ratio. At 300kV input the output voltage will be
30V. Readings will correspond to the type of meter used. AVG will show AVG, RMS will show
RMS etc. The meter impedance needs to be 10MDC, and 1 M, ≤ 200pF AC for the highest
possible accuracy. Readings will correspond to the type of meter used. AVG will show AVG, RMS
will show RMS etc. Use DC range for DC signals (10MΩinput meter).
Select desired mode for voltmeter.
Activate high voltage source.
Measure voltage as required.
De-activate high voltage source and assure, as appropriate, that high voltage source is de-
energized and discharged.
After assuring that high voltage source and unit are de-energized and discharged, all leads
and connections may be disconnected and unit packaged for transport or storage.
3) STAND ALONE METER MODULE OPERATION:
It is not recommended to operate the meter head without the divider. The meter head is not a
stand alone voltmeter.

SECTION 6: CALIBRATION
It is recommended that calibration be performed on a yearly basis.
CAUTIOIN: CALIBRATION SHOULD ONLY BE DONE BY PERSONS FAMILIAR WITH HIGH
VOLTAGE TESTING AND SAFETY PROCEDURES!
CALIBRATION PROCEDURES
Due to the complexity and the standards required to calibrate this instrument, Phenix
Technologies does not recommend customer calibration. For further information please contact
our Service Department.

SECTION 7: MECHANICAL MAINTENANCE
SURFACE
All surfaces will provide adequate protection against the elements in normal use. It is
recommended that the finish be wiped down with an ordinary household cleaner for longer life
and for proper electrical operation of the unit. Also inspect all fabrication joints for oil leakage. If
a leak is found, consult the Phenix Technologies’ Service Department.

SECTION 8: STORAGE OF EQUIPMENT
If the equipment will be stored for a prolonged period, the following precautions are
recommended.
The equipment should be covered and kept in a warm, dry environment (95% maximum
humidity, 5 to 50 degrees C).
Prior to placing the equipment back into operation, all aspects of the maintenance schedule
should be strictly adhered to.

SECTION 9: TROUBLESHOOTING
METERING MODULE
Unit will not turn on: Battery may be discharged. Recharge battery
Unit blanked out during testing because of transient discharge occurrence and won’t come
back on by cycling the power switch: Carefully remove front panel, and unplug the battery
pack for approximately 30 seconds, then retry power switch.
Unit does not measure correctly after flashover or transient discharge occurrence: U5
possibly damaged. Replace with LT1055 OP Amp.

SECTION 10: RECOMMENDED SPARE PARTS
Phenix Technologies recommends that the customer purchase and stock the following parts for
normal maintenance of the unit. The recommended quantity should be sufficient to support the
unit during normal operation.
If the unit will be operated at an isolated site for an extended period or will be subjected to
unusual stresses, a larger quantity of parts should be stocked as spares. In such a case, contact
your Phenix Technologies’ sales representative for a recommendation.
