User questions & answers

Question:

How long are the wires from plug to lead

Answer:

When connected in parallel, the light will stay on as long as one of the two sensors still detects motion and time has not expired on the time delay. Once BOTH sensors no longer detects motion and the time delay has expired, the load will turn OFF (lights off). If this is the desired results, then yes it can be installed in parallel however, both sensors MUST be on the same circuit (meaning both must be getting the “HOT” from the same wire that comes from the electrical panel or in other words, same circuit breaker).

User questions & answers

Question:	Is the voltage reading adjustable for accuracy purposes
Answer:	It needs to go above 11.8 to stop blinking, according to reviewer “Ken R.” saying “Flashes to indicated a low-battery voltage starting at 11.8 volts (handy for my application, but not a great feature for those planning to routinely monitor voltages 11.8 or less).”
Question:	How do you hook it up
Answer:	No
Question:	Does the meter display quit blinking once voltage is above 11.5 volts
Answer:	Hello, the exact dimensions are shown in ͏one of the photos, however the diameter is 2.5" and the bulbs uses a standard medium base (E26). Thanks for choosing Bioluz LED.

User questions & answers

Question:	Where can purchase just the wires? Can anyone help please
Answer:	Harbor Freight gives these away free sometimes and they come with battery installed and written instructions.
Question:	How would I use this meter to check how many amps an outlet has
Answer:	As far as I know NO, there is no audio confirmation of continuity, but then I never needed it for that, I just use it to check voltage on my little AAA and AA rechargeable Amazon Batteries. I really like th meter though,, as well as all the other Amazon items I have purchased. Have a good one. P. Haddock
Question:	Is there an online manual for this somewhere
Answer:	I'm pretty sure these are 36" long leads. There plenty long for my needs and for most any application. Very flexible and very sharp tips on probe ends. Small enough to backprobe some of the small block plugs I work with on major appliances. I would purchase again.
Question:	No audio indication of continuity
Answer:	Yes, look at the current rating of the motion sensor. It will have a current rating. Your light is probably drawing less than 1 amp.

User questions & answers

Question:	What did you use to mount it to handlebars
Answer:	It can be wired directly to a battery but you will need to have some sort of switch or disconnect otherwise it will always be on even if the engine is off. Best option is to tie into a circuit that only turns on when the key is on.
Question:	What is the accuracy spec of this meter.? Do they come in blue led
Answer:	They make some tachs. Look on Amazon. Whether they match or not is up to you.
Question:	Does it just wire to the battery
Answer:	As far as I know, there is no place which just see the test pin out wires. Hope it helps your search.
Question:	Great product. Does Keenso make a matching tachometer
Answer:	We are also assuming the OP knows the difference between amperage and voltageas most people dont. Th9s meter can measure voltage but not amperage. A typical wall socket will have 110v @15-20 amps

User questions & answers

Question:	Do the 2 gauges have common or individual grounds? (could they be used individually across 2 batteries in series
Answer:	Yes. I currently have a single batter set up. The bottom just reads 00.0. When I add a second battery later it will read. I thought it would be annoying, but it is not.
Question:	How many amps can it handle
Answer:	yes it will stay on . I would wire in a 12v two pole relay to your ignition switch. So when you turn your key on ,it will close relay, and power up your voltmonitor.
Question:	Can this be used with a single battery setup
Answer:	I used a 1" handlebar clamp from ebay. There are several styles, I used the thin cast ones, they are either black or chrome. Not very big, but they have held the meter in place so far. I mounted small turn signals with them also. I did have to file the clamps out some to get a tight fit on the handlebars though.
Question:	If i wire this to each battery directly, will it always stay on
Answer:	Undetermined

User questions & answers

Question:	which setting is for volts, and which is for ac
Answer:	The V with the two lines is DC volts and the line with the squiggly line is AC volts.
Question:	is the continuity test audible
Answer:	Good question. and I can't find an answer it doesn't say but in the picture when it's showing someone testing continuity it shows that it's beeping what it doesn't say that it does beat and we've got two people on here that say it does not and two people that say that it does so good luck I'm looking for one that is audible myself why all multimeters don't have an audible noise when you have continuity I will never know either that or you can have one that has a paper thin needle that jumps and you can't see it and you have to take your eyes off of what you're working on to see if you have continuity and when you move your head you lose contact and it's such a pain in the ass
Question:	Is this unit protected by a fuse? If so, is it replaceable? My last meter was fused but it was soldered. I couldn't easily replace it
Answer:	I had to replace the ammeter fuse (because I forgot to switch the hot (red) test lead from the left side to the middle, before testing my car's battery voltage). That fuse is 10A 600V. I looked around for those & couldn't find them, but found 10A 250V and these worked OK. They're 20 x 5 mm ( .2 x .79") ceramic fast-blow. https://www.amazon.com/gp/product/B07JFDTTMJ/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
Question:	Can this handle being plugged into a wall socket? Also, can someone give a walkthrough of how to safely test a socket
Answer:	plug the red lead into the meter socket marked COM and the black into the center meter socket. Set the dial to V~ (for AC volts) on the 200 scale (for household current) insert one probe lead into each of the wall socket's vertical slots and move them around a bit inside the outlet slots to make sure you're getting a good connection, if in doubt plug a lamp or something into the socket. If you suspect the outlet socket itself has failed carefully remove the wall plate in order to access the actual wires connected to the outlet to be sure it's either a dead circuit or the outlet itself has failed.
