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: | 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. |

Fluke 101 Basic Digital Multimeter
User questions & answers
Question: | does this have 10 megaohm impedence |
Answer: | I am pretty sure the question refers to the load impedance of the meter and not its resistance range. BTW, the manual for this meter is readily available on-line, where you will learn that the input impedance is >10M for AC/DC measurements and >1M for AC mV measurements. |
Question: | The Fluke website states it measures capacitance and it has the symbol. Why are people answering no that it can't |
Answer: | It can measure capacitance. Of course I cannot answer why others say it can’t. Must naturally be set correctly. The manual has a full description. |
Question: | Does this meter check microfairings |
Answer: | This meter does have a capacitance test. |
Question: | Can you measure ghost voltage with it |
Answer: | If you are asking about a parasitic draw I would not since it doesn't have a amp setting I have not personally tried with mine but I know even with my fluke 87 it is still tricky so you don't blow the internal fuses. Hope that helps |
