Even if a meter is well rated, it will unlikely offer full protection at the component level should there be a drastic spike in a circuit. Just stick with measuring single phase and low voltage systems with these meters. Some are rated as high as CATIII to 600V, but that is based on low energy services as opposed to three phase induction motor kind of voltage / current. Pocket versions are simply not meant for that kind of power. In short, if you are looking to measure current and high energy circuits, start looking at a ‘proper’ multimeter. Display resolution will never be as high as the best DMMs, but when you’re buying a pocket meter, are you really that interested in perfection to the nth degree? Pocket DMM Safety They typically have similar architecture at the circuit board level, minus the same component capabilities regards current and voltage.

Pocket multimeters can be just as accurate as full size or compact ones. Although a $20 meter won’t replace your $300 Fluke, in the above scenario, something is better than nothing.

They are especially useful when traveling, where having a full size meter might not be feasible.

The best of it is you can simply throw one into a laptop bag, under a motorcycle seat, in the dashboard and of course in your pocket. These feature-packed versions thus favored by those into electronics and they can even handle the tasks presented in most HVAC situations. Great for verifying voltage or checking the continuity of a circuit or wire, the best pocket multimeters may also come with extra features like voltage detection and capacitance. While they shouldn’t be regarded as a replacement for a professional meter, and certainly not in a heavy industrial environment, pocket meters are very useful and do a good enough job for 90 percent of jobs around the home or car. Pocket multimeters seem to have come a long way since the days of massive, bench-mounted voltmeters.
