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.

Question:	Is the unit truly auto-ranging? i see a "range" button on the unit pictured
Answer:	Yes
Question:	What batteries does it use
Answer:	9v battery. It does come with it. You will have to install.
Question:	For a hobbyist, why would I not buy a $20 multimeter vs something
Answer:	Fora hobbyist the really cheap meters are the best because sooner or later one will test something that will ruin the meter. This meter is really an intermediate meter which is above the hobbyist stage but still below the professional stage. An no, buying a Krug doesn't make you a professional.

User questions & answers

Question:	Would you choose this model or another for automotive diagnosing
Answer:	To answer your question I'm a master Automotive technician most of the people in the business use flukes but our use these ones because they are accurate and work just as good as the fluke when it comes to Automotive Diagnostics. There is nothing you can't do with this digital multimeter that you can do with a fluke
Question:	I have been trying to measure the ac/dc amps with this but doesn't work. i wanted to know if i am missing something or its actually faulty
Answer:	Make sure you have the leads in the proper slots or ports for the amperage reading.
Question:	What does "4000 counts" mean
Answer:	Counts and digits are terms used to describe a digital multimeter's resolution. Today it is more common to classify digital multimeters by the total counts than by digits. Counts: A digital multimeter resolution is also specified in counts. Higher counts provide better resolution for certain measurements.
Question:	Do the Battery Test selections test under load
Answer:	battery test 1.5v 30 ohm load 9v-12v 300 ohms load

Question:	Do this multimeter comes with a case, if not do anyone where can i buy one
Answer:	no it doesn't come with a case
Question:	are there test leads with aligator clips available for this meter? if so where
Answer:	Test leads with alagator clips do not come with the meter, but a set with alagator clips are available on Amazon that should work. I hope this helps.
Question:	Is it possible that the leads supplied with the meter don't plug into the front of the unit? Mine seem too large in diameter to push into the ports

User questions & answers

Question:	Does the volt meter itself ever need recharging
Answer:	You have to replace the battery at some point!Maybe soon if you leave it on!
Question:	could this measure down to say 0.1 ohms
Answer:	If you really need to measure extremely low resistances accurately, you can get a power supply that you can set for a constant current of 1A, and put it through your test load. Then put your meter in the DC millivolt range and read across the load. It will display the resistance in millohms, so a reading of 100 mV would correspond to 0.1 ohms. Few people need to measure such small resistance values, but some specialized things like coils and inductors have test specifications down in those ranges.
Question:	Help. i have a short or bad ground somewhere in my automobile, battery and alt new - i think wires going to the pcm. will this help identify? thanks
Answer:	This is called a parasitic draw and a multi step process can isolate it down to a single component. You start with checking the draw on the battery. Remove the negative terminal and set the meter to 10 AMPS with the black lead plugged into the the COM connector female on the bottom and the red plugged into 10 amp female on the far left. Clamp the black lead to the negative battery cable connector that you removed and touch the red lead to the negative terminal. If you get a reading higher than a quarter of an amp you the battery is discharging and depending on the draw it will run down over night. A tip: Make sure everything is off in the car by closing the doors and removing the bulb from courtesy engine compartment light. If the bulb is inaccessible just duct tape the switch down. Also if you entered the car to pop the hood you should wait for the computer to go back to sleep - about 20 minutes - before running the test. If there is a draw you should start isolation by pulling fuses - when you pull the right fuse the reading will drop to 1/4 amp or so. The fuse fronts a wiring harness bundle and you can see what circuits it is protecting on a schematic - first thing to check are switches on the bundle and any after market additions to the harness. Most times it will be an open switch but a poor installation of additional lights or accessories is also a high suspect spot for a short. If a switch replace it or even just open it (turn it off). If a short you need to isolate the individual circuit on the harness bundle. Short isolation is a difficult time consuming task and rather than describe it I recommend that you watch this video on YOUTUBE. It is the best I have found for going all the way to the source of a short. Second tip is to have a helper with the fuse pulling and remember that some vehicles have 2 or 3 fuse boxes. GOOD LUCK, this is time consuming but not rocket science. https://www.youtube.com/watch?v=q5zLxD74r20
Question:	Does it have a beep function to check connections
Answer:	If you're referring to the Testing for Continuity function -- yes. "The buzzer sounds if the resistance of a circuit under test is less than 70 ohms".
