The ultimate shirt-pocket sized meter. Only 3/8" thick and less than3 oz in weight with full functionality offering ac and dc voltage to 600 V, ac and dc current to 2000 µA, resistance to 6 Megohm, capacitance to 2000 µF, frequency to 30 kHz, diode test and continuity w/beeper. It also offers VolTect, a built-in, non-contact voltage detector for ac voltages. Another key feature is AutoTect, which automatically selects between ac voltage, dc voltage or resistance measurement based on the test point to which the leads are connected. Fully auto ranging, this meter offers nine different measurement functions plus features that are usually found in much more expensive and larger meters. The digital display is oversized with large digits and unit icons in the display. In spite of its size, this meter is fully safety rated to CAT III300 V, CAT II 600 V and is UL listed.
