A Pearson Current Monitor intended for general use is adjusted at the factory to yield an initial-pulse-amplitude error within specification (either ±1% or +1, -0% depending on model), when terminated in a high impedance load such as an oscilloscope. The equivalent circuit of nearly every Pearson Current Monitor is that of a voltage generator in series with 50 ohms.


Pearson Electronics provides calibration services for its Wide Band Current Monitors that are in compliance with ANSI/NCSL Z540-1 and ISO 9001:2015, traceable to NIST.   Please see our Test Summary and Sample Test Certificate for more information.
