About meter

This meter is housed in a professional, low-profile, screw-less plastic case and uses a single 9-volt battery.It is constructed from top-quality components installed on a professoinal finish printed circuit board .Three additional improvements are a high-brightness LED display module (as specified by Bob),improved circuit protection from charged capacitors, and improved micro-controllerfirmware that provides a longer, 3-minute, automatic switch-off time.

It measures an aspect of electrolytic capacitor performance which is very important, and impossible to check with a regular capacitance meter, the mentioned aspect is: the equivalent series resistance, or ‘ESR’
