How to use MuMetal to shield the magnetic fields emitted from electrical wiring, and why in some cases shielding will not work
Review of the Tenmars TM-196 Radio Frequency Test Meter, by Michael R. Neuert, an electromagnetic test engineer/consultant in northern California.
SPECIAL UPDATE: The TES 593 is an older style RF meter that we no longer recommend, for several reasons.

Part 9: What level is safe, what do the numbers mean? 19:17
In my opinion, the Alpha UHS is the lowest cost gaussmeter available with enough accuracy to be trusted, that also has the following two important features: (1) it is a 3-axis meter and thus can detect the total magnetic field in all directions, and (2) it can measure the ELF magnetic fields emitted from power lines, transformers, electrical wiring, electrical panels and everything that runs on regular electricity, as well the the VLF magnetic fields from computers, TVs, fluorescent lights and LED lights. Here are easy instructions to help you measure the fields accurately, and also help you determine what the particular EMF sources actually are.

In my opinion, the TriField is a handy meter to try to detect all 3 kinds of electromagnetic fields within one instrument, but is definitely not the recommended meter to measure EMFs due to serious accuracy and sensitivity issues. #1: The meter tends to be very inaccurate and read high when measuring the magnetic fields, as dirty magnetic fields trigger it to give high measurements. #2: For both the electric fields and the radio frequency fields, it is just not sensitive enough to even begin detecting the common exposure levels found in the typical home or office (it does not even begin to register anything till the field level is quite high, and thus is not very useful). Here are easy instructions to help you use the TriField Meter both to detect the EMFs, and also to help you determine what the sources actually are.
Some of the strongest electric field exposures are created by ungrounded computers. Michael Neuert, an EMF test engineer with over 23 years experience, shows an actual client example of high body voltages from an ungrounded iMac Computer, and how this was easily fixed.
