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.
Do not use this probe to
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.

Warning
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.

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.

The input impedance in almost all ranges of Fluke
multimeters is ~10 M
Ω
. 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
Ω
.
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.

The 80K-15 (Figure 1) is designed to work with a meter that
has an input impedance of 10 MΩ (
±
1% ). A meter with an
input impedance less than 10 MΩ 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 MΩ 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.
2.
3.
Turn on a compatible voltmeter or multimeter and
select the voltage measurement function.
Select an appropriate voltage range (i.e., 1 volt reading
per 1000 volt input. See Table 1).
Connect the probe’s output leads to the voltmeter or
multimeter input terminals.

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.
