The ACDC-400 400A AC/DC Clamp-on Multimeter is a versatile instrument that incorporates the features desired for testers in its price range.
The ACDC-400 is a versatile clamp‑on multimeter that measures AC/DC current up to 400 A and voltage up to 600 V. It offers resistance, continuity, data‑hold, MAX/MIN recording, relative measurement, backlight, an analog bar graph, and automatic or manual range selection. The instrument can accommodate conductors up to 30 mm (1.18") in diameter.
The package includes the instrument, test leads, a rubber test‑lead holster, a user manual, a carrying case, and batteries. Safety compliance follows EN 61010, Class 2 double‑reinforced insulation, and CAT III 600 V over‑voltage rating. The device operates from two 1.5 V AAA batteries with an estimated 25‑hour battery life.
