User questions & answers

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.
Question:	Does continuity test produce a beep
Answer:	Yes. Turn dial to diode setting and press FUNC once. Beep is plenty loud. Great meter for the price.

User questions & answers

Question:	Can this multimeter be used for an Automtive Tech
Answer:	While this multimeter can do plenty of things for automotive. Most serious mechanics get the 87 or 88 series.
Question:	what is the range of the capacitor that can be tested in this model
Answer:	hope this helps. Range/Resolution: 1000 nF / 1 nFRange/Resolution: 10.00 μF / 0.01 μFRange/Resolution: 100.0 μF / 0.1 μFRange/Resolution: 9999 μF / 1 μFRange/Resolution: 100 μF to 1000 μFAccuracy: 1.9% + 2Range/Resolution: > 1000 μFAccuracy: 5% + 20%
Question:	Can this multimeter be used on vehicles for a parasitic load test? I don't want to spend over $400 for the Fluke 88 as it is for personal vehicle use
Answer:	it has been used on motorbikes for sure. It just needs to be in amp mode. If you're doing parasitic load, then you're focused on DC Amps. The 117 has up to 6, while the 88 has up to 10. I don't see a big issue as you're just doing parasitic, not actual use. If anything actually pulls more than 6, you'll blow the internal fuse and have to replace it, but that's about it. Shouldn't be a problem(I've just tested mine on my car and it works).
Question:	What are the differences to pick between the Fluke 117 and the Fluke 115? My intended use would for ham radio and kit-building of electronic kits
Answer:	The 117 adds • VoltAlert™ technology for non-contact voltage detection • AutoVolt automatic ac/dc voltage selection Both are handy but not essential. Be aware of none of these 'electrician' Flukes (115/116/117) read milliamps or microamps -- essential for electronics troubleshooting & design work but unnecessary for electrician tech work. That said, when reading current in amps they do seem to read accurate down to around at least 0.010 amps (10 milliamps) or so.
Question:	is it two prong or three prong? can't see it in the picture
Answer:	It's actually made to be plugged into a grounded wall socket, replacing the 2 3-pronged outlets with its 6 available grounded outlets. It can even replace the outlet cover and be screwed into place. I've got a bunch of these and love them.
Question:	What are the actual dimensions of this unit
Answer:	against the wall, mine is about 4 inches wide, 4 3/4 inches tall, and about 1 3/4 inches deep
Question:	Will this work with half-switched outlets (where one outlet is always live and one is switched), or do all the outlets get power from only one outlet
Answer:	All power for this device comes from the TOP outlet of your receptacle -- so if that is switched then all outlets on this device will be switched (or if your bottom outlet is switched then all outlets on this device will NOT be switched).
Question:	Can this actually completely replace the existing outlet wall plate, or does it only plug in/screw on TOP of the wall plate
Answer:	This can replace the existing wall plate -- that's how I am using 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.

User questions & answers

Question:	can i get an accurate amp reading on kitchen appliances such as toasters, microwaves with this meter
Answer:	Sounds like what you need is a Kill-A-Watt meter (brand name). You plug the meter in the wall then plug the appliance in the meter. Real simple. Gives amps, watts, volts, etc.
Question:	Can the clamp measure voltage without load
Answer:	The clamp (non-contact) can only measure current (amperage), not voltage. To measure voltage, you'd need to use the probes on a physical connection (terminal or bare wire).
Question:	I am working on a light fixture - if I want to test the actual wires (and not outlet) to see if they're live, what setting would I need to do this on
Answer:	Nobody else said it, but if you use the clamp meter, it must be around a SINGLE wire, it will not work if you clamp around both wires of the cable. You must separate the wires, and clamp only one wire. And the clamp is only gonna measure current, so if the lamp isn't working, this probably won't work. If the plag is plugged-in though, there will be a voltage present, so a non contact voltage tester should be sufficient enough to tell you it's live. Please be careful.
Question:	people said it has an audible beep for continuity and 2 people said it doesn't. What is the true answer
Answer:	It does have an audible beep for continuity. It is an option that must be activated by pushing a button to enable this feature of continuity testing.

User questions & answers

Question:	Range of uf
Answer:	From Instruction Manual Pg. 4, "Electrical Specs": Capacitance (Auto-Ranging) 40.00 nF - 4000uF. Tip: Type "Klein MM700" into Google and choose Klein's website to see all the Spec's for the MM700.
Question:	Will it check dc amperage
Answer:	Yes. The meter will ALWAYS give you a LEADS warning if you switch to current measurement. This is to remind you that you need to relocate the red lead to one of the current jacks. Unless you are sure you are measuring micoamps or milliamps, start with the 10A jack.
Question:	Does this dmm have a function for testing transistor hfe? i do not see it so i assume no
Answer:	You assume correctly. There is no dedicated transistor test function on this meter.
Question:	Que incluye
Answer:	Estuche, cables y baterías!!!!
