  • #1440191
  • Manufacturer: Fluke
  • UPC #095969001120
  • Model #80K-40
  • The 80K-40 is a high voltage probe designed to extend the voltage measuring capability of an AC/DC voltmeter to 40,000 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. The probe provides high accuracy when used with a voltmeter having 10 Megohm input impedance.

    Detailed Description
    (Manufacturer # 80K-40 )

    • A high voltage probe that allows a multimeter to measure up to 40,000V respectively. Intended for low energy applications only
  • The 80K-40 will achieve rated accuracy when used with a voltmeter (ac or dc) having an input impedance of 10 M? ?1.0%.*
  • Specifications for the probe are as follows: ?Voltage Range: 1 kV to 40 kV dc or peak ac, 28 kV rms ac Input Resistance: 1000 M? Division Ratio: 1000: 1 (1000X attenuator) Accuracy DC: 20 kV to 35 kV: ?1% at 20?C to 30?C; add 1% at 10?C <20?C and >30?C to 45?C. (For total measurement accuracy add accuracy specification of voltmeter being used.) 0 kV to <20 kV and >35 kV to 40 kV: ?2%. Accuracy AC: 60 Hz, ?5%. Safety: Meets IEC 1010-2-031:1993, Type B, 40 kV dc or, peak ac, 28 kV rms ac, Overvoltage Category I (voltages derived from limited energy transformer). * The input impedance of Autoranging Fluke handheld digital multimeters varies as a function of range. The only range that deviates significantly from 10 M? is the 3V (Models 21, 23, 25, 27, 70, 73, 75, 77) or 4V (Models 10, 11, 12, 29, 79, 83, 85, 86, 87, 88) range where the impedance is 11.11 M?. To enhance the measurement accuracy when using this range, apply a correction factor of 0.99, i.e. multiply the displayed reading by .99. ? This probe is intended for low energy applications such as CRT and similar circuits. Above 2000 meters altitude, and up to 5000 meters, derate linearly the working voltage from 40 kV peak to 28 kV peak, and derate linearly the transient overvoltage from 80 kV peak to 57 kV peak. Transient overvoltage refers to micro-second duration impulses caused by lightning or load switching.
