Why does it light up when shaken

It lights up when shaken or tapped against your finger to let you know the battery is good. It's suppose to do that. It's one of the great things about the fluke

Nobody knows...seriously though we assume that it works off an EM field created by AC current which is always changing. DC fields don't change and are not detected. But if a field existed and you moved the detector through it, you would get a temporary signal...my theory anyway. FYI, pro electricians always would induce those false signals before testing a conductor to check the instrument. Then they added the test button.

I have two of them. I bought one about a year after the first because I thought I had lost the first, but then I found the first later. Neither of mine light up when shaken.

I believe motion is what wakes the tester up. When not in use, the unit goes into a very low battery drain mode. When you pick it up and move it, it goes into an active mode and the light flashes to indicate it is operating. After you have used it and it is sitting for a while, it goes to sleep again.I thought I had seen this information in the Fluke instruction manual but couldn't find it today.

Hi Bennet, Sorry for late reply. If the battery is not charged fully, its light flash. But once it is charged fully, its light stop flashing. If you have any further questions, please let us know it.

It is a led light witch pops out more then a dot on the screen. In reality there is no difference just appearance. I can focus on the dot more sense it lights up

It has a turn switch and if not turned up there is no light. A light occurs if switch moved up at all.

I can hear a slight sound on mine, along with the light going off. It seems to take several seconds to reactivate if there is constant movement.

It is a continuous light source. It is probably not bright enough to give you any kind of artistic reflection.

There is a round thing behind where the animals spin. It lights up. I think if it is off, you can see a reflection in it. I'm sorry this is a jumbled answer, couldn't figure how else to word this.

Hi, I checked this again with a flashlight and it does have a red color when you shine a light on it, but it is hard to see. Sorry to mislead you.

It becomes obvious when the battery's need recharging by the lack of brightness from the light. I bought an extra set so I have fully charged battery's in case I need the light for a longer period then one set lasts. I hope this helps..

Check your settings, I believe it has a built in light sensor, try changing the settings

The letters on the keys do light up as well. There is a light button to turn the light on/off and adjust the brightness.

It's kinda a multi-colored thing, its maybe pink, blue, purple or something similar...I don't think it's just pink when it lights up, but it's going fast so I don't really pay too much attention.

No! I've had my light a couple of years and this problem has never happened. I use it for an hour every night to take care of the animals. Make sure that you don't overcharge it. I charge mine in my car so that I can hear when the charge is completed.

You do have to shake it, but nothing serious, just a bump and you will see the light come on, and the charging begin.

The top "red button (not a button though) lights up. I guess it would be like a "click indicator". It flashes with the music.

Hi,If you "jiggle" the receiver (collar) then the light should come on. They are supposed to be designed to deactivate when the collar is not moving, in order to save battery power. As soon as you shake it a bit the light should come on. Check both sides to know which side the light is on. As always make sure you have well charged batteries in both the remote and the receiver. Hope this helps.
