User questions & answers

Question:	Hi, Is there a protection plan options for this item? if yes, what's the cost of the plan. Thanks
Answer:	Why bother, the cost is low and there is a return policy.
Question:	is the a category 3 and true RMS meter
Answer:	NO
Question:	Is your meter made here in the usa,or is it out sourced from china
Answer:	Of course in China , as almost tech gadget, it would have costed at least 10 times more if made in USA, and not any better
Question:	Does this work with square waves like those for the output of a 12V landscape lighting transformer? If so, what setting should be used
Answer:	A square wave can be expressed as a sum of the fundamental frequency and many harmonics, the meter is designed to measure just the fundamental , 60 hz, if it can do a proper filtration of it, which is pretty difficult, so NO

User questions & answers

Question:	Does it buzz for continuity
Answer:	It does not buzz for continuity but buzzes for the diode test. I have 3 different multimeters and none of them buzz for continuity.
Question:	what batteries does this need
Answer:	The battery comes with the tester. It's a 9volt single cell.
Question:	How do i turn it on? put battery in. pushed hold then backlight. nothing happens. i followed directions put wires in set dial put on aa battery
Answer:	Maybe your batteries are dead. Mine worked just fine.
Question:	Is it able to accurate measurement
Answer:	I've had very good results for both DC and AC voltage measurements. So far very good with AC current.

• ACCURATELY MEASURES: AC/DC Voltage, DC Current (Not AC Current), Resistance, Continuity, Diodes and more.
• TROUBLESHOOTS SAFELY: Automotive and household electrical problems safely and accurately; Overload protection on all ranges
• EASE OF USE: Data hold and large digital display with backlit LCD for visibility in dimly light areas; Sampling speed: 2x per second
• 1 Year Warranty. Built-in kickstand for hands-free use. Protective rubber corner guards for drop protection
• NOTE: This meter can not test AC Current; Ensure your multimeter is set to the correct setting before testing

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.

User questions & answers

Question:

Is the cord length referring to the test leads length? How long are the test leads length? 5 in. not much to work with

Answer:

Hello, the test cable of our multimeter (including the terminal contact) is about 27.56 inches (about 70CM). Our ELVESHOME multimeter is better than AstroAI Digital Multimeter or Sperry Instruments STK001 Non-Contact Voltage Tester or WeePro Vpro850L Digital Multimeter or Sperry Instruments GFI6302 GFCI Outlet / Receptacle Tester are cheaper and easier to use, versatile and have batteries. Pocket multimeter to take with you! worth having! THANKS!
