The Megger DCM310 and DCM320 Digital clamp meters are for use during the installation, maintenance, and checking of electrical systems. Both meters will measure AC current (50 - 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 DCM310 also has a max-hold feature to automatically store and display the maximum value measured over a period of time. The DCM320 has the benefit of measurement ranges for a.c. and d.c. voltages up to 600 V, and resistance up to 20MΩ, via the terminals and supplied test leads. It also has a continuity buzzer that operates up to 20Ω.

Both meters are safety rated to IEC 61010 CAT III 600 V, 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 1.2 m drop onto a hard surface without damage.
