In addition to basic functions such as measuring AC/DC voltage and current, frequency, capacitance, resistance, diode checking, and continuity checking, the 3801 features functions such as an AC + DC mode, temperature measurement, and pulse output. DC voltage measurements are accurate to within ?0.06% rdg. ?3 dgt. (in the 4000 count mode), assuring accurate measurement for all types of electrical equipment checks. Display can also be switched to the high-resolution 40000-count mode.

Models 3801 to 3805 bear CE markings and conform to standards such as the IEC61010-1 international safety standard and EMC related standards. Further, these handy units have been designed with an emphasis on safety, and come equipped with a standard 600 V fast blow fuse in the current connector and a cushioned holster that provides protection against shock in the event of accidental droppage.

A true RMS system accurately measures harmonic wave components generated by inverters and provides the following functions in addition to frequency and temperature measurement.
