I'm trying to measure ELF with my EMF-390 but I can't seem to find a function to do this. I've seen quite a few videos mention ELF but without showing how to do it. Is it possible? And if so, can someone clue me in? Thanks.

Hello, yes it can detect ELF. Just point the device close to the source and read it with the EMF/mG from the unit.

In table mode you can read the frequency of the EMF.

Be sure to look at the owners manual on the company website to get familiar with the menu controls. If holding the device horizontal with the buttons to the right, the buttons are, from the top, POWER, UP, DOWN, BACK. To change screen modes, press the BACK button to get a menu. Use the arrow buttons to select a screen. Either wait for it to set or press the POWER button briefly to set. I'm assuming you're talking about magnetic fields, which this instrument refers to as EMF.
* On the all in one screen, press UP repeatedly until the main display shows EMF.
* On the vertical mode screen, and now holding vertically, press the UP button (now pointing right) until it selects EMF/EF. Press the DOWN button (now pointing left) to switch between EMF and EF.
* On the table mode screen, now holding horizontally, press the UP button until it selects EMF/EF. You can read total EMF and EMF in each axis.
* On the emf graphs screen, press the UP button until it selects EMF/EF to read total EMF or press the UP button until it selects XYZ-EMF to read the EMF in each axis.
