Defective? When set to read voltage, without being connected, the display has numbers that seem to be effected by shaking the unit.

My Klien multimeter doesn't seem to be effected from shaking the unit but every multimeter that reads voltage in the thousandths and ten thousandths range will pick up ghost voltage. Im not sure if its static that causes this or not but my Fluke meters do the same thing.

If the radio still works I would say either the LCD display went bad or the power from the control board was lost. There might be a small fuse. The display should have 5 to 10 volts DC. If voltage is present then the display will have to be replaced.

The display is clear, it may just be a defect in yours or something with the settings.

Mine appears to do the same thing (in hundredths & thousandths digits) especially when I shake the unit or leads. Goes to steady zero when I touch leads. I don't think this is defect.

The one that I have is reliable and reasonably accurate down to about 80V. Below that voltage it rapidly becomes inaccurate and the display flickers. I do not know the maximum voltage. (I tested it with a variable-voltage transformer.)

You might have a bad battery. A cell can be intermittent and the voltmeter will still read okay, since it doesn't check current. I suggest you test each battery with a battery load tester.

I have only had this monitor a short time so I have no idea what will happen later. Nor have I checked it with a doctor. Also, I wouldn't know if the readings were errors! but would probably go in to have my blood pressure read if the readings seemed unusual. After looking at other responses I see that this is about the ERR message. I have only had that once. I am more concerned with the accuracy of the readings.

Mine was not DOA we touched it came on got it to 0.0 then someone stood on it, registered weight then oooo came w/the rest of the reading. Try to make sure it is 0.0 first before getting on.

It doesn't seem to happen like that. If the batteries need changing, you might get an error instead of a reading, or like mine did just today, it would not turn on until I changed the batteries.

When everything is OK; it shows a "0". The numbers increase if there is a problem.. Just beware of what is said about plugging it in to 110 power as soon as you install the batteries or it will alarm very LOUDLY and scare the dickens out of you.

Bad connection??I haven't had this happen. Been using the gauges about 2 years now.If voltage is right around the cutoff of 4.5V I suppose it could blink on/off as the voltage hovers around that point. Gauge puts a tiny load on system so volts would drop, then without the load V would increase again over 4.5V so it would light up again, and the cycle would repeat.

Your display should have a blue background and should be super easy to read. Perhaps try replacing the battery and if that doesn't work, I'd request an exchange.

I have not had that experience. Wish I could help, but mine is working perfectly.

Yes, the display reading is in red text again black. When I come up the stairs at night with no lights I am able to see the reading of 0.

The display on my remote tells me the time even when it is turned off. It displays additional status info when it is turned on. It sounds like your display is faulty if nothing shows up. I suggest you call the service phone number listed below the warranty at the back of the Instruction Manual. Staff was helpful the one time I called them.

It looks as though you got a device that went through QA only on paper. I personally would take a pic and send it off to the manufacturer.However, if you want to save a lot of time put a continuity test and just use it as it is. It's ac current so it really shouldn't matter.

Either something is wrong inside the unit itself, or perhaps there's a problem with your electric supply, such as bad grounding or voltage out of range.
