Q: What Input Impedance does my Fluke Multimeter Have?

A: The Input Impedance for Fluke's multimeters is typically 10MΩ.  Fluke Clamp Meters are 1MΩ Input Impedance. The exception is the 11x series multimeters (the 114, 115, 116 and 117); these models have 10MΩ impedance for DC Voltage and 5MΩ for AC Voltage.  Specific Meter Input Impedances can be found generally by contacting the manufacturer; it is not typically included as a specification in the datasheet.

Knowing the Input Impedance of your Voltmeter is important when using our Voltage Test Point Products as the Input Impedance of your meter will determine the Voltage Reading Reduction that you see on it when using our PESDs.
