identifiesconditionsandacti onsthatcouldcausedamageormalfunction
intheinstrument.
Toreducetheriskoffireorelectricshock,donotexposethisproducttorainor
moisture.Themeterisintendedonlyforindooruse.
Observepropersafetyprecautionswhenworking withvoltagesabove33Vrms,46.7
Vpeakor70VDC.Thesevoltagelevelsposeapotentialshockhazardtotheuser.
Beforeandafterhazardousvoltagemeasurements,checkthevoltagefunctionona
knownsourcesuchaslinevoltagetodeterminepropermeter functioning.
Themeter meets UL/IEC/EN610101Ed. 3.0, CAN/CSAC22.2No.61010 1 Ed.3.0,
