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.

Answer:	Yes. Take off the plate that acts as a flip out stand.
Question:	Is this meter made in usa and also can it be used for household and automobile purposes
Answer:	Made in China. Klein says of the MM400: "For use in basic and controlled electromagnetic environments such as residential, business and light-industrial locations." I've used it for residential and automobile purposes.
Question:	Does it come with a case
Answer:	Mine did not come with a case, but you can order one. Look at the bottom of the listing at "frequently bought together" or something like that verbiage to show what case to order. I prefer a hard case, so I did not order the soft zipper one.

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:	Will we be able to add a bluetooth upgrade to our meters since it indicates an updated meter will have it and it also has the symbol
Answer:	Yes
Question:	How long is the warranty
Answer:	No not good driving gloves
Question:	Just wondering if you ship this item to Australia

User questions & answers

Question:	What are the concrete tips for automatic shutdown
Answer:	Step 1.) Run around in circles until u get too dizzy to continue or 15 min has passed, then it will auto shut off. 2.) There is no step two. If you have further questions or need more concrete tips, just continue repeating step 1 until it sinks in.
Question:	W/ backlite on I tilt the meter away from me the display is readable but once I tilt it towards myself the display becomes unreadable, is this normal
Answer:	Yes, with the baclklight on, it's viewable from straight-on to tilted away from yourself, but with the top tilted towards you it loses all contrast. Side-to-side viewing angle is a good. This is a common trait among some LCD displays.
Question:	I want to measure current flowing to my car starter when cranking engine. Does this clamp on meter measure DC current when using clamp
Answer:	Yes, It can read DC starting current with the clamp when set to DC measurement. Reading moves fast but I take video with mobile phone camera and rewind to see the 268A when starting a Nissan Frontier 2.5 L engine. Reasonable current though I cannot check its accuracy yet. I buy meter to monitor DC charging current and confirm non-running car leaking currents under 50mA but need to wait 20 minutes after engine off to let car computer stabilize from initial shutoff which can cab be as high as 0.6A. With this meter, I also find about 10mV leaking voltage on plastic surface between terminals at new battery (due to acid filling spill at manufacturing?) from club store which I need to reduce the Voltage drop to less than 0.1 mV by scribing several grooves on plastics surface around terminal posts. Calibrate to zero by holding Z/F button few seconds before measurement can help read accuracy. I am happy with this meter for the price. Hope you too if do not have time to find a better cheaper on
Question:	how accurate is th DC current measurment
Answer:	I have not checked it against a reference, but I have done some measurements on my car with this. It seemed to reflect a reasonable value when the battery charger was on, showing charging current. and It showed a big current for the started that was believable. When you first set it, you can press a zero button to zero it out. Then I looked at a really bad solar panel that could only put out about 50 milliamps when shorted, and it was able to show that pretty well. So the bottom line, if you are going to use this for debugging stuff, it seems pretty good. If you are going to measure calorie input to control a chemical reactions in a pharmaceutical lab, I can't say. For me, it is just cool that it can do a DC current in the first place. Has already come in handy as I was able to determine my alternator was not charging my battery quite easily.

Product features

To measure Direct Current

Specifications:

If current> 3A, the orange display lights up.

The measuring range of DC current is 60A/600A. Accuracy: ±(2.5%+5).

Note:

Before measuring the DC current, long-press and hold the Z/F key until the ZERO character appears to clear the data.

To measure Alternating Current

Specifications:

If current> 3A, the orange display lights up.

The measuring range of AC current is 60A/600A. Accuracy: ±(2.5%+5).

Note:

To measure the current you need to clamp the meter around one of the wires and not the whole power cord. The power cord contains two wires carrying current and ground wire. The current in two wires always flows in opposite directions, so the magnetic fields from two wires canceling each other, therefore the meter reads 0 A.

Grasp the individual current conductor to be measured and close the current clamp again. The measured conductor must be placed in the center of the clamp, otherwise, additional errors will occur.
