Amprobe Charts Full Size Digital Multimeters

These digital multimeters have even more functionailty than Compact Multimeters and are built for industrial and facility maintenance applications. The full size multimeters have a higher category rating. CAT IV means it is more rugged to withstand high voltage transients. Backlight is for use in dark work areas.
