This is an Auto Range Professional Multifunction AC/DC Clamp Meter with 3999 counts. Capable to measure DC and

AC voltage, DC and AC current, Resistance, Capacitance, Temperature (°C), Frequency, Frequency from the clamp, Duty Cycle,

Diode and Continuity Tests.

In addition to features are Relative Measurement Mode (Zero Function) and Over range protection. Simply clamp

around an electrical conductor to allow the electrical current in the conductor to be measured, without having physical contact

with it, or to disconnect the wiring through which the current is flowing.

It complies with all essential health and safety requirements set out in European Community Directives. It also meet

internationally proven safety standards such as IEC1010-1, IEC1010-2-032, concerning electrical measuring instruments with

double insulation overvoltage category 1000V CAT II 600V CAT III and pollution degree 2.
