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:	item 37772 iinstruction availble
Answer:	I would say it has pink undertones. It does not drape. More of a quilt like material. I love ours. Using it as a throw over our leather chair.
Question:	Can this multimeter test a 208 cable as well as a
Answer:	Greetings, This Product is made up of cotton Material and filling is of poly fill ( Polyester) Thank you
Question:	Does this come with the Thermal probe
Answer:	Of the two sides of the throw, one is patchwork and one is all the same fabric. The patchwork side is not all pink...lots of richer and darker, oranges, turquoise, greens... the one-pattern other side is basically a darker pink background.
Question:	Auto turn off to save battery life
Answer:	My afghan also says "dry clean". I suspect that since in many countries, the quality of the cotton and/or the dyes used on the fabric, may indicate dry cleaning over laundering. Personally, I launder mine... I let it soak in cold water, a mile detergent plus I add a cup of white vinegar to "secure" the colors for about 20 minutes. Then I continue with the gentlest cycle my washer has. The spinning action of many washers can be hard on some items, so I let the water drain for awhile and then take the item out and towel roll it until it is no longer dripping...drape it over my drying rack until it's dry and it's good to go. Also... for the way I use my afghan...more decorative and only at night if the temp drops..... it does not require washing very often.

User questions & answers

Question:	How the luminosity measure is taken? There is a special device
Answer:	I got the blue one, sorry. But the blue has blue quilted squares on the front and a solid blue print on the back if that gives you a guess of what the grey one is like....sorry.
Question:	I need a replacement thermocouple to plug into this device, is that available
Answer:	Designs on both sides; but different ones. The Seller would be better able to answer your question.
Question:	Can you test car batteries with it
Answer:	No I would not consider it light blue but it’s not navy blue. It’s a little darker than the darkest blue on the front. Hope this helps.
Question:	How does this meter "measure up" when it comes to taking db levels? Can it be done via the probes or must it be done via a built in speaker? Thanks
Answer:	It's embossing process, not stitching, the front side and reverse side are two different color of embossing. One is beige, one is dark grey.

User questions & answers

Question:	Is this a counterfit?? The ad claims it is made by Sinometer. No where on the box,manual or meter shows the name Sinometer
Answer:	Both sides are the same color, so that when you reverse it, the color and pattern are exactly the same.
Question:	How can you turn off the audio alarm? The alarm in my new meter will not turn off
Answer:	It is reversible.
Question:	How many decimals places of accuracy does it have when measuring resistance or ohms. I need one that does fractional ohm readings to the 1000th
Answer:	Fabric is cotton. Batting/filling inside is poly.
Question:	does this measure capacitance
Answer:	Label says made in China. The throw has a nice quilting and is made of 100% cotton and is soft. Washes well. I really like it.

User questions & answers

Question:	I own an Innova 3300 that over estimates voltages, 9V PS reads 10.5, 12V reads 13.8, 3.7V battery reads 6.24 what can I be doing bad
Answer:	I would advise against it. This is only a CAT 2 rated meter. That means the internal safety features are not sufficient to handle the higher potential voltage and energy that could come about at a meter panel. http://www.ni.com/white-paper/5019/enYou really want a CAT 3 meter if you want to measure any live breaker panels.If you are going to test for bad circuit breakers that are disconnected from the live wiring then you could use this meter to check for continuity and the like. Do not use this meter on anything more powerful than a wall outlet. CAT 3 meters are available for not much more money.
Question:	What's the lowest ohm reading it is capable of
Answer:	Yes, the Innova is great for finding parasitic leaks in boats and cars. Turn everything off..... EVERYTHING and then disconnect the negative battery cable. Insert the meter in series with the neg bat terminal and the end of the cable. If there is a current leak it will show on the meter when it is set on the AMPS function. Becareful that you don't turn anything on when the meter is connected because the AMP mode is not fused. If a current reading shows on the meter start pulling fuses and disconnecting devices until the reading drops to zero therefore isolating the problem
Question:	Can I use this meter to test for bad circuit breakers at electrical panel or electrical outlets at home? I'm newbie; want learn how to use. Thank u
Answer:	I'm assuming you have tried moving the main test mode selection dial to some position other than 'off'. Do you have another 9V battery on hand you could use instead? It's possible the battery you received with the tester is bad. If another battery does not solve the issue, then it's possible you received a bad unit.
Question:	I am searching for current leak in a boat (12v battery). Will this dial down to low enough amps to diagnose? Thanks
Answer:	It will measure down to 0.01mV in both - AC and DC modes, thou manual says - 0.1mV.
