The DSA540A Sperry Instruments Snap-Around clamp meter is a 10 function, 26 range auto-ranging unit engineered to measure up to 400A AC/DC current, 600V AC/DC voltage, 40 Mohm resistance, frequency, capacitance, diode test and continuity. Similar to digital multimeters, clamp meters offer a large range of functions and include LCD screens to display results but they offer the additional unique ability to measure current without having to contact live conductors. This unit features a data hold and relative measurement to maintain the reading on the liquid crystal display and auto power-off functionality to extend battery life with a low batter indicator to ensure you won't get incorrect readings due to low batteries. Audible beeper permits easy continuity check. We consider safety first; this instrument has been designed and tested and certified to cETLus with CAT II t 600 V and CAT III 300V ratings.
