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.
