Today we’re going to take a look at the AEMC 3731 Clamp-On Ground Resistance Tester. To be honest, I tend to think that electricity is a kind of magic. The best way I’ve found to understand it is to make comparisons to the flow of water and the various aids and impediments to said flow. Water, being a much more tactile phenomenon is easier for the more lay folks like myself. This analogy leaves out some of the unique and complex features of electricity but it works as a guide.
When it comes to testing equipment it can be easy to get lost in the latest and greatest technology. For ground resistance testing, sometimes less is more. The AEMC 3620-150 3-Point Ground Resistance Tester happens to be one of these testers. This ground resistance tester has a large analog display that shows direct readings from 0.5 to 1000 ohms. There is also a manual zero adjustment to increase the accuracy of your readings. Looking at the AEMC 3620 you can see there is very little to set up.
Portable Megohmmeters are not your everyday item, but when dealing with high voltages you want to err on the side of caution. The AEMC 6550 and AEMC 6555 Portable Megohmmeters test DC voltages up to 10,000 and 15,000 respectively. These units come built into a rugged IP54 rated case that can handle the rumble and tumble of the everyday real world environment you work in. Both units offer live measurement of voltage to be sure you are working under safe conditions.
AEMC PEL 100 series power meters (PEL 102 and PEL 103) do everything you would expect out of a high quality meter in this price range with a few super cool features that place them above the competition in certain areas. First off, these loggers will take readings on single, dual, and 3 phase circuits in VA, W, and var for power and VAh, Wh and varh for energy and are designed for use in 1000V Cat III and 600V CAT IV environments.
