80K-15
Electronic Air Cleaner Probe
Instruction Sheet

Introduction

The 80K-15 Electronic Air Cleaner Probe (hereafter referred
to as “the probe”) is a low energy probe that extends the voltage measuring capability of an ac/dc voltmeter or multimeter.
Properly connected, the probe is rated to 15 kV Overvoltage Category I. The use of the probe is restricted to low energy applications, which are energy limited circuits like electrostatic air cleaners.
measure high voltages on power distribution systems.
The probe is a precision 1000 : 1 voltage divider formed by two matched resistors. The unusually high input impedance offered by these resistors minimizes circuit loading and thereby optimizes measurement accuracy.
Do not use this probe to

Read First: Safety Information
WWarning
To avoid possible personal injury or electrical shock:
Use the probe within its voltage ratings and in dry
conditions (no condensation is present).
Be familiar with and exercise all possible high
voltage safety practices.
DO NOT use this probe to measure high voltage on
power distribution systems.
Always hold the probe by its gray handle. Never
allow the probe tip or the yellow part of the probe to make body contact.
Before making a measurement, make sure that the
side of the probe plug with the GND tab is plugged into the low (COM) terminal of the meter.
Attach the grounding lead to earth ground.
Use a meter with an impedance of 10 MΩ ( ± 1% ).
Using a meter with an input impedance less than 10 MΩ reduces the accuracy of the reading by causing it to be lower than the voltage present.
DO NOT use the probe with a Fluke multimeter that is in the kChek or Automatic Selection mode (i.e. Fluke 16, Fluke 12B etc.). The input impedance in these modes is very low.
Make sure the probe tip is firmly attached to the body of the probe.
DO NOT use the 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.

Specifications
The 80K-15 Electronic Air Cleaner Probe achieves its rated accuracy when it is used with a voltmeter or multimeter (ac or dc) with an input impedance of 10 MΩ ± 1%.
The accuracy of the probe does not include the accuracy of

the meter. To get the accuracy of the system, the accuracy of the meter must be added to the accuracy of the probe.

Figure 1. 80K-15 Electronic Air Cleaner Probe
The 80K-15 (Figure 1) is designed to work with a meter that has an input impedance of 10 M ( ± 1% ). A meter with an input impedance less than 10 M can produce readings lower than the voltage present. This can pose a serious hazard when a dangerous voltage is present.
The 80K-15 represents a 1000 M load to the circuit being measured, or 1 µA per 1 kV. Table 1 shows the circuit loading and input/output characteristics of the probe over its measurement range.
Taking care to follow the safety practices under “WRead First: Safety Information,” use the probe as follows:
1. Turn on a compatible voltmeter or multimeter and select the voltage measurement function.
2. Select an appropriate voltage range (i.e., 1 volt reading per 1000 volt input. See Table 1).
3. Connect the probe’s output leads to the voltmeter or multimeter input terminals.
Note
The input impedance of the Autoranging mode on Fluke handheld digital multimeters varies by range.
The input impedance in almost all ranges of Fluke
multimeters is ~10 M
. The exceptions are: the 3 V range on the Fluke Models 21, 23, 25, 27, 70, 73, 75, 7; and the 4 V range on the Models 10, 11, 12, 16, 79, 83, 85, 86, 87, 88. In the ranges on these
multimeters, the impedance is 11.11 M
.
To improve the measurement accuracy of the probe when using these ranges on the models indicated, apply a correction factor of 0.99 i.e., multiply the display reading by 0.99.

Performance Test

Verify the accuracy of the probe by measuring a 15 kV dc (± 0.25 %) voltage source. When used with a compatible dc voltmeter, the probe should measure the source with ± 1% accuracy. No calibration adjustments are needed.
