Introduction
WWarning
Read Safety Information before you use the
Calibrator.
The Fluke 707Ex mA Calibrator (hereafter, "the Calibrator")
is a compact and easy to operate sourcing and measuring
tool. The Calibrator tests current loops of 0-20 mA or 4-20
mA and measures dc voltage to 28 V. It comes with a set of
alligator-clip test leads, a 9 V alkaline battery installed, and
this Users manual on a CD.
The Calibrator is ideal for use in confined and restricted
spaces within Ex-hazardous areas according to
IEC/CENELEC and Factory Mutual.
