10mmindiameter.
Donotusethemetertomeasurecurrentsabovetheratedfrequency
(400Hz). Circulating currents may cause themagneticcircuitsoftheJawsreacha
hazardoustemperature.
(Application andRemovaloftheClampon Jaws) Pressthejawtriggerand
clampthejawsaroundconductor(s)ofonlyonesinglepoleofacircuitforloadcurrent
measurements.Makesurethejawsarecompletelyclosed,orelseitwillintroduce
measurementerrors.Enclosi ng conductor(s) of morethanone pole ofacircuit may
resultindifferentialcurrent(likeidentifyingleakagecurrent)measurement s. Alignthe
conductor(s)totheJawscenterindicators(RegularorAmpTip indicators where
applicable) as muchaspossibletogetthe bestmeasuringaccuracy.Forremoval,
pressthejawtriggerandremovethejawsfromtheconductor(s).
Adjacent currentcarrying devices such as transformers, motors and
conductorwiresmayaffectmeasurementaccuracy.Keepthejawsawayfromth emas
muchaspossibletominimizeinfluence.

Anantennaislocatedalongthetop rightend of
the stationary clamp jaw, which detects electric field surrounding energized
conductors.Itisidealfortracinglivewiringconnections,locatingwiringbreakage s and
todistinguishbetween liveand earthconnections.
Formorepreciseindicationoflivewires,suchas
distinguishing between Live and Ground connections, usedirectcontacttestingwith
onesingletest probe via aninputterminal.T heCOMterminal(Black)hasthebest
