Overview
The True RMS Ampstik has been developed specifi cally for mea sure ment of AC cur rent
in the electrical utility industry. The True RMS feature allows accurate mea sure ment of
current even when the nominal waveform is distorted or when harmonics are present.
This in stru ment can be used re mote ly with any hot stick and universal chuck adapter or
can be hand held. The in stru ment has no moving parts and does not require clamping
onto the wire. The molded housing is water resistant and will withstand high physical
impact. The following specifi cations apply:
