80K-6
High Voltage Probe
Instruction Sheet
Description
The 80K-6 is a high voltage probe designed to extend the voltage
measuring capability of an ac/dc voltmeter to 6000 volts peak AC
or DC Overvoltage Category I. This means the probe can only be
used to make measurements on energy limited circuits within
equipment. Examples include high voltage within televisions or
photo copy machines. DO NOT use this probe to measure high
voltages on power distribution systems. A 1000:1 voltage divider
provides the probe with a high input impedance. The divider also
provides high accuracy when used with a voltmeter having a 10
megohm input impedance. A molded plastic body houses the
divider and protects the user from the voltage being measured.
Specifications
The 80K-6 will achieve rated accuracy when it is used with an
ac/dc voltmeter having 0.25% accuracy, or better, and an input
impedance of 10 megohms ±10%. Specifications for the probe
are as follows:
Voltage Range: 0 to 6 kV, dc or peak ac
Input Impedance: 75 megohms nominal
Division Ratio: 1000:1
Accuracy:
DC to 500 Hz: ±1%
500 Hz to 1 kHz: ±2%
Above 1 kHz: Output reading falIs.
Typically, -30% at 10 kHz.
Temperature:
Storage: -20 to 60°C
Operating: 0 to 50°C
Temperature Coefficient: 100 ppm/C
Relative Humidity: 20 - 80%
Altitude: 2000 m
Shock and Vibration:
Shock: 1 m Drop
Vibration: 5-55 Hz swept sine 3 g max.
Dimensions: 24.89 cm (9.8 in) (probe body), 5.10
cm (2.0 in) max. width
Weight: 12.7 g (45 oz)
Safety:
CAN/CSA C22.2 No. 1010.2.031-94 & IEC 1010-2-031:1993,
Type B, 6 kVDC or peak AC, 4.24 kV rms AC, Overvoltage
Cat. I (Voltage derived from limited energy transformers).
Measurement Considerations
Before attempting to use the 80K-6, the following paragraphs
should be read and understood. Particular attention should be
given to Operator Safety.
Operator Safety
Indicates the operator must refer to an explanation in
this manual.

WWarning
• To avoid damage or electric shock, use within
ratings and under dry (no condensation)
conditions.
• To avoid electrical shock, the 80K-6 user should be
familiar with, and exercise, all possible high-
voltage safety practices. When handling the probe
the following additional cautions must be taken:
• 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.
Voltmeter Compatibility
The 80K-6 is compatible with any ac or dc voltmeter that has an
input impedance of 10 megohms ±10%. Voltmeters with higher
input impedances require the use of an external shunt to obtain
an accurate measurement.
Use the following formula to determine the value of an external
shunt resistor:
Rs Rm x 10
Rm 10
=−
Where: Rs= Shunt Resistance in Megohms
Rm= Voltmeter Input Impedance in Megohms
(> 10 megohms)
Circuit Loading
The 80K-6 represents a load of approximately 75 megohms to the
circuit being measured (13 µA per 1 kV). See Figure 1. To more
accurately determine the load resistance, measure the resistance
of the 80K-6 at its voltmeter connector and multiply the measured
value by 1000.

Operation
Use the following procedure to operate the 80K-6:
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 80K-6.
Never use solvents or abrasive cleaners.
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
4.910±0.020 inches. Make the adjustment using the
solder connection at the rear of the metal probe
coupling.
