GENERAL SAFETY PRECAUTIONS
HIGH VOLTAGE
This equipment is capable of providing POTENTIALLY LETHAL VOLTAGES!
Improper operation or test practices may result in injury or death to the
operator or surrounding personnel.
The operation of High Voltage test equipment should only be performed by
personnel familiar with HIGH VOLTAGE testing and safety procedures. The
operator of this equipment must be aware of all hazards associated with High
Voltage testing. The operator is responsible for himself and others in close
proximity of the testing area.
Some General Safety Practices for working with High Voltage Test Equipment
have been listed below for your reference.
•Become familiar with your instrument before performing an actual test
•Know your work area, check that all circuits are de-energized and locked
out.
•Never work alone; always work with another qualified worker.
•Mark off entire work area with barriers and warning tape.
•Make all personnel aware of your testing activities.
•Be aware of dangerous conditions that may arise from energizing a test
specimen.
•Never modify test equipment, modifications to equipment could introduce
an unknown hazard or hinder a designed-in safety feature.
•DO NOT operate damaged equipment. Remove power, and do not use
the equipment until safe operation can be verified by service-trained
personnel.
Phenix Technologies, Inc. assumes no liability for unsafe or improper use of test
equipment.

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 Service Department
at Phenix Technologies before proceeding.
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.

4-1
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.
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.

5-1
SECTION 5: OPERATING INSTRUCTIONS
1. DIVIDER WITH METER MODULE OPERATION:
•Make sure connections have been made as described in “Set-Up” section.
•Press and hold power button to turn metering module on.
•Select the desired range for voltmeter based on the expected input signal level.
•Select desired mode for voltmeter with function buttons.
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
20kV, the range selector has to be on high range, regardless of the expected ripple voltage
level. To avoid damage to the unit, ascertain that 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.
•De-activate high voltage source and assure, as appropriate, high voltage source is de-energized
and discharged.
•Press and hold power button to turn metering module off.
•After ensuring high voltage source and divider are de-energized and discharged, all leads and
connections may be disconnected and unit.
•Do not subject unit to Flashovers. Damage may occur. If meter becomes disabled from Flashover
or Transient condition, refer to Troubleshooting section.
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 a 10,000 to 1 ratio. At 50kV input, the output voltage will be 5V. 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 (10 meg input meter).
•Select desired mode for voltmeter.
•Activate high voltage source.
•Measure voltage as required.
•De-activate high voltage source and ensure, as appropriate, that high voltage source is de-
energized and discharged.
•After ensuring 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.

6-1
SECTION 6: CALIBRATION
It is recommended that calibration be performed on a yearly basis.
CAUTION: 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.

7-1
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 nothing stronger than 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 Service Department at Phenix Technologies.

8-1
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.

9-1
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.
