Calibration and Testing
Service Detail from Pearson Electronics, Inc.
A Pearson Current Monitor intended for general use are 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 MIL-STD-45662A, traceable to NIST. Please see our Test Summary and Sample Test Certificate for more information.
