Mine shows a reading of zero all the time, when I hold it near the battery compartment then it goes nuts.. how to operate this thing?

Hold it to where it does not go off and move it towards a power cord or a fluorescent light. It should go off the closer to the power it gets. It does not tell you if it is measuring EMF or RF energy.

It's a crazy device. Does it go crazy when you turn on the device? Best with AC current

I tested it against other emfmeters.No documentation is available. I suppose it measures V/m for low frequencies waves, not. radiofrequencies.It worths price se paid!

Hold it near your computer screen and you should get some high readings or take it outside and hold it against your electric meter and if you are still getting 000 it may be something else because wants you turn it on and whole it near any and everything there produces electric and it should show you that it is working if not you know what to do on the return

It's actually a very interesting device. If you notice if you touch it against your skin it gets a reading. This device measures static magnetic and dc fields. If you take a ballon, rub it on the carpet and bring it near the meter you will get a reading. It's like an ion/static meter. It's really amazing. The people who giving bad reviews is because they are trying to measure magnetic fields and its not working. There's a great video on YouTube about how it's advertised wrong and measures ions. Hope this helps.

I would check that your batteries are pushed tightly down into the compartment. I haven't had any problems with mine at all, so I'm just guessing here. Good luck

I've got the same problem. It gets as far as flashing lb/kg and that's it. Nothing responds after that and I don't get any numbers to move up or down with. The printed directions are not helpful at all because it doesn't respond after the flashing lb/kg. Am probably going to ship it back. Has anyone had one arrive with an almost dead battery? Maybe that's the issue.

Same here. I think it is the auto-ranging function. Turn off the auto-ranging and it should settle down. I have zero variability when set to volts range. Given the price of the meter I decided not to worry about this glitch.

I just got this and have the same problem..... there are NO numbers on the screen to set anything with. I bought a new battery and installed that, but had the same results.... nothing

I have the same problem as you!I've changed batteries and still behaves in the same way.I bought mine at Home Depot, but If a had read the reviews before buying I would not have acquired it

Change the batteries and try it. Return unit if it still doesn't work properly.

Must be a problem. Try disconnecting the unit and pressing the charge % indicator button. A digital display should light up and advise the % of charge. If it is 99-100% you should be good to go. Turn the unit off and wait for the opportunity to amaze yourself and others with the power of your "toy".

The battery is low and it is about to go dead. Anyway that is what happens to mine. Hope that helps!

mine won't even turn on. I don't know if the indicator light is just weak or what but right now its doa. and what do you do when the battery runs out?

Only thought I have is that you have the polarity reversed on the battery leads. If the leads are correct, the controller is faulty.

Sam, I am not sure, but it sounds like a battery issue. Mine works from a half block away from my house. I assume you pulled the little battery saver piece all the way out.

If you haven't done this, (1) replace the batteries and (2) reset the unit by the front reset hole located just under and to the left of the read out. If "8"s still appear, it's been my years of experience with this unit to replace the unit.

It seems to calibrate itself upon startup. It will calibrate itself to zero if you turn it on with a container that you intend to fill already on it. As for it's need to be calibrated for accuracy, we'll we just have to trust to the gods of electronics. That said, I've never felt it might be even slightly beyond negligible where error is concerned. I'll buy another if mine ever poops out!

There should be a small hole on the back ov the unit. For some reason the unit has frozen up. Use an unfold paper clip to trigger the manual reset. That's all I can suggest other than return it where you got it for refund!

Make sure after you plug in the battery that you put is on a flat surface so it can calibrate properly. Also make sure that the motor cover is keeping the motor from backing out.

After my last response I remembered how it was wired. You will need to read voltage at the battery. On the back of the meter is a plug with a 2 wire pigtail. The pig tail wires are red and black. The black wire goes to the negative post on the battery. The red wire goes to the positive post on the battery and the battery voltage will light up and you can read it all the time. The problem wiring it this way it is always on and can drain the battery of its voltage over time. The other way is wire the meter through an off and on switch. The black still goes to the negative battery terminal but you need to bring a red wire from the positive side of the switch and then on the wire coming out of the switch take that wire and connect it to the positive battery post. When you flip the switch off and on the meter will register. If you are not sure when the switch is on or off. A multimeter can be used. Set to ohms put one lead on one switch connector and the other lead on the other switch connector. One side will be able to read ohms and the other side will not as you flip the switch back and forth. The side that reads ohms goes to the positive terminal. Hope this all helps.
