WWarning
∙To avoid damage or electric shock, use within ratings and under dry (no condensation) conditions.
∙To avoid electrical shock, the
∙When making a measurement, never make body contact with the probe tip or the red portion of the probe. Always hold the probe by its black handle.
∙Before making a measurement, make sure that the ground side of the output connector is connected to the voltmeter’s common terminal.
∙The clip lead must be attached to earth ground.
∙Do not use the probe if it is damaged. Before using the probe, inspect it for cracks or missing plastic. Pay close attention to the probe body, tip and insulation surrounding the connectors.
∙Make sure the tip is firmly attached to the body.
∙When servicing, use only specified replacement parts.
∙Do not operate probe around explosive gas, vapor or dust.
∙Do not use the probe if it operates abnormally. Protection may be impaired. When in doubt have the probe serviced.

Use the following formula to determine the value of an external shunt resistor:
Operation
Use the following procedure to operate the
1.Inspect the probe. (Refer to the preceding Warning.)
2.Connect the probe cable to a compatible voltmeter. (Refer to the preceding Warning.) Use a shunt resistor if required.
3.Select an appropriate voltage range (1 volt reading per 1000 volt probe input).
4.Connect the ground lead of the probe to earth ground. (Refer to the preceding Warning.)
5.Hold the probe by the black handle and connect the probe tip to the circuit being measured. Observe the voltmeter reading.
Maintenance
Performance Test
Verify the probe accuracy by measuring a 5 kV dc ±0.25% voltage source. When used with a compatible dc voltmeter, the probe should accurately measure the source voltage to within ±1%. No calibration adjustments are provided on the probe.
Cleaning
Use a soft cloth dampened with distilled water to clean the
Disassembly
Use the following procedure to disassemble the probe:
1.Unscrew the black handle from the probe, and slide the handle onto the cable.
2.Unscrew the metal tip one turn, and push in on the tip until the internal assembly snaps free of the housing. Remove the tip.
3.Withdraw the internal assembly from the probe by pulling the metal ring over the threads on the probe body.
4.Logically reverse this procedure to reassemble the probe.
Caution
To avoid probe damage after repair, measure and, if necessary, adjust the outside distance between the ring and the probe coupling on the internal assembly before reassembling the probe. The distance must be
Rs
= Rm x 10
Rm − 10
4.910±0.020 inches. Make the adjustment using the solder connection at the rear of the metal probe coupling.
Where: Rs= Shunt Resistance in Megohms
Rm= Voltmeter Input Impedance in Megohms (> 10 megohms)
