Megger Digital Clamp Meter is ideal clamp meters for use during the installation, maintenance and checking of electrical systems and equipment. The large clamp jaw enables cables to be measured up to 27mm diameter, so covering the majority of applications within the electrical system installation industry. It measures up to 400A AC with low current ranges for improved resolution. It measures AC current (50 to 60 Hz) up to 400A with a Data-hold feature to freeze the displayed value for use in confined situations where the display may be difficult to read. The DCM320 has the benefit of measurement ranges for AC and DC voltages up to 600V and resistance up to 20M?, via the terminals and supplied test leads. It also has a continuity buzzer that operates up to 20?. It is safety rated to IEC 61010 CAT III 600V, so offering high levels of protection to the operator. Carrying cases are included and even without the case, the instruments are rated to withstand a 1.2m drop onto a hard surface without damage. Ideal for use by anyone working on basic electrical systems or equipment, this instrument is also suitable for the majority of applications encountered by the electrical contractor.
