Amprobe PM55A Pocket Multimeter with Non-Contact Voltage Detection Digital multimeter measures alternating current (AC) voltage and direct current (DC) voltage to 600 volts (V), resistance to 6 megaohms, capacitance to 2,000 microfarads, frequency to 30 kilohertz (kHz), and AC and DC microcurrent to 2,000 microamp Average-sensing meter provides accurate readings when measuring linear loads where the current or voltage has a sinusoidal waveform Non-contact voltage detector senses AC voltage without making contact with the circuit Meter measures 4.4 x 2.1 x 0.4 inches (H x W x D) and can be carried in a shirt pocket when not in use Meets International Electrotechnical Commission (IEC) safety standard 61010 and is certified for category II installations up to 600V and category III installations up to 300V Safety: CAT II 600 V,CAT III 300 V,Pollution Degree 2, Class 2 AutoTect feature directs the meter to know if it is measuring ac or dc volts or resistance with no user interface The AutoTect feature has lower input impedance which zeros out ghost voltages Voltect feature is a built-in, non-contact voltage detector Automatic Power Off
