1.0 Introduction / Scope of Supply
The UNITEST CHB 15 and CHB 35 Clamp Meters and CHB 10 Clamp
Adapter are universal, multi-purpose IEC 1010, EN 61010 electrical
measuring instruments. They comply with the standards and provide
safe, reliable operation. The clamp meters and adapter are a valuable
tool for all sorts of measurements in both trade and industry.
The UNITEST Clamp Meter CHB 35 can, in addition, be used to
measure true RMS values; this is particularly important for currents
and voltages which do not conform to a true sine-wave.
