This document describes the specifications and features of the DM73C model pen probe style digital multimeter. The multimeter has a measurement range of 600V AC and DC, with safety ratings of CAT III 300V and CAT II 600V. It has an improved dc basic accuracy of 0.5%, resistance up to 34 MΩ, continuity beeper, and includes accessories such as an alligator clip, ground test lead, spare probe tip, and installed batteries.
The DM73C is a pen‑probe style digital multimeter offering 600 V AC and DC measurement ranges, Cat III 300 V and Cat II 600 V safety ratings, and a 3400‑count LCD with an analog bar graph. It provides accurate DC voltage, AC voltage, resistance, diode and continuity testing with resolutions down to 0.1 mV.
The unit includes an alligator‑clip lead, ground test lead, spare probe tip, and installed LR44 batteries. It features auto‑power‑off, low‑battery indication, and UL 3111‑1 listing, making it suitable for indoor use up to 2000 m altitude.
