Safety Intended for indoor use and protected by double insulation
per EN61010-1 and IEC61010-1 2nd Edition (2001) to CAT III 1000V & CAT IV 600V. The
meter also meets UL3111-1(1994)* and CSA C22.2 No. 1010-1-92* to CAT III 1000V.
Terminals (to COM) ratings:
V: CATEGORY III 1000 VOLTS AC & DC, AND CATEGORY IV* 600 VOLTS AC & DC
A/MAµA: CATEGORY III AND CATEGORY IV* 500 VOLTS AC AND 300 VOLTS DC
*Category IV safety standard (for DMMs) was rst released in IEC61010-1 2nd Edition in
year 2001, and was yet a UL published standard at the time this manual was written
UL Certication Meters that bear the UL marking have been investigated by
UL headquarter in the USA per UL standard UL3111-1 1st Ed to its highest CAT III rating
and international standard IEC61010-1 Second Edition (year 2001) to CAT IV rating. The UL
markings as ‘UL Listed Cat III only’ and ‘UL Classied to IEC61010-1 2nd Ed. Car IV’
E.M.C. Meets EN61326 (1997, 1998/A1), EN61000-4-2(1995) and
EN61000-4-3(1996). Also meets former standards EN55011 (1991) and EN50082-1 (1997).
