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.

Note

The input impedance of the Autoranging mode on Fluke handheld digital multimeters varies by range.

Figure 1. 80K-15 Electronic Air Cleaner Probe

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

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.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.
