The IDEAL® 61-327 Digital Multi Meter is a Cat III 600 rated manual range digital multi meter. It measures up to 600 VAC and DC, resistance, continuity, diodes and tests batteries via test leads (included). It's display can be backlit. The unit uses an illuminated red LED in the center of the meter and emits audible tones to notify when voltage is above 30 V, and when continuity is detected. The rubber boot has two probe storage points, has built-in probe tip holders to allow measurements while holding the meter in one hand and the second lead in the other hand. The meter has a hanging strap mount (compatible with all other IDEAL® meters with this feature) that allows for a hanging strap (sold separately) to be attached to the meter so it can be hung from a nail, screw or magnetic surface. A rugged over molding enhances grip and drop protection. This meter features a HOLD and selectable auto power Off functions. The meter comes with 3 1.5 V AAA Batteries and an easy open, fully accessible storage pouch with a belt loop that allows for meter, probes and thermocouple storage.
