The Amprobe DM78C digital multimeter is a compact, pocket-sized tester with 5 functions and 16 measurement
ranges. Suitable for a wide range of measurements in a variety of applications, this Amprobe multimeter has
a CAT II 600 V and CAT III 300 V safety rating. In addition, the Amprobe DM78C is UL listed.
The DM78C multimeter measures AC and DC voltage to 600 V and resistance to 34 MΩ. The Amprobe DM78C has a
diode test and continuity check with beeper alert.
Additional features of this Amprobe multimeter include autoranging and manual range with lock, overrange
indication, data hold, and a low battery warning. Measurement results are displayed on the DM78C’s 3-3/4
digit LCD display with analog bargraph.
The Amprobe DM78C multimeter ships complete with:
