Uses for Electrical Meters Part 2

by Andy on December 5, 2011

While last week’s article focused on some more common electrical meters, sometimes you need a more specialized device. This week we are going to look at a few of these specialized meters and what they are used for.


Nanocoulomb Meter Nanoammeters are similar to nanocoulomb meters in that they both test very low currents. However, the nanoammeters only test the current (amperes) while nanocoulomb meters test for coulombs (amperes per second). These devices are used for precise measurements, testing devices that have very low currents.


Charged Plate Meter:

These meters are used to monitor ionization systems. Sometimes ESD-safe work mats and wrist straps are not enough and an air ionization system is needed for even more protection. Air ionizers work by adding ionized particles to the air, which neutralize built-up charges on devices. Because they work by changing qualities of the air, it is not possible to physically see if the devices are working to their specifications. A charged plate monitor allows you to monitor the ionization system to make sure it works and to find malfunctions before they hurt ESD-sensitive devices.

Ground System Tester:

Ground system testers are also used to monitor ESD-safe equipment. Instead of looking at the air ionization, this tests both personal and workplace grounding systems. This includes items like wrist straps, heel straps, table mats, and floor mats. Typically they can tell you how high or low the resistance is to make sure that the items are within the accepted limits to protect ESD-sensitive items.

This concludes our series on uses for various electrical meters. Are there any meters that you know of that you aren’t sure of their uses? Let us know below and we will help figure it out!

Also, don’t forget about our additional Monroe meters getting added to our current line soon.
