multimeter for car

I want multimeter for my car that can handle a variety of tasks such as
measuring voltage,
current,
resistance,
possibly more advanced features like diode testing and continuity.

I am searching on a website, but I can't decide what to order.
 
invest in good tools, they will last a lifetime.
I still use my Fluke 79 multimeter after almost 30 years of intensive use. It has been all over the world.

China copy=bad copy.
 
Of late, I have had very good experiences with Korean-made multi-meters. They are inexpensive, lightweight BUT somewhat bulky. The ones I've used have had a hard life (hanging off the sides of turbines and inlet air filter houses and gas valve compartments I often drop my meters. Yes, they get dinged and scratched--but the LED covers have never cracked or broken and the meters have continued to work well (I kept my meters in good calibration, and I never had a complaint from either of the two calibration services I used).

Meters can be purchased from RS or from ebay sellers, or most other electrical suppliers. Big box stores like Home Depot and Leroy Merlin also sell them. I would always opt for Fluke, but sometimes I just needed a second meter--and the Korean multi-meters I bought and used were highly accurate for high-frequency AC voltage measurements at low voltage levers (less than 10 VAC RMS). And they have been inexpensive. Yes, I took grief for my Korean-made multi-meters from my buddies and some site personnel (who had Fluke meters but couldn't use them properly and did not take care of them).

For automobile use, one could buy a voltmeter from just about any auto supply store and get reasonable quality which would last a long time with good care. Some (but not many) will have back-lighting on the display (can be handy when working under a car or car hood at night.

The only issue I had with many "off-brand" multi-meters is the quality of the meter leads. I always carried extra Fluke meter leads and they always fit the shielded banana plugs of every multi-meter I used. Fluke meter leads were slightly longer (very often required for industrial applications) and made of good quality components (insulated wire; pointed tips and insulated ends). Some of the lesser-known meters I have purchased and used had some very thin meter leads and cheap materials for tips and insulated wire--which didn't give me any confidence when measuring 125 VDC or 440 VAC.

I recommend getting a supply of fuses for the voltmeter--personally I like fast-blow fuses for my meters, as opposed to slow-blow fuses. But if you don't use a multi-meter often and you will need to switch between voltage and current measurements it's almost guaranteed that you will blow a fuse after a current measurement when you forget to move the meter leads to the voltage measurement plugs...! (Ask me how I know these things. Painful personal experience, that's how.) Learn where the fuses are located, what fuse(s) you need for spare(s) and buy a few (three or four). You'll be glad you did!

Again, for most automotive applications a meter from the local hardware or auto parts store is probably ge--good enough!
 
Continuity measurements for most automotive applications are "simple" measurement for just about any multi-meter. You will most likely only be checking to see if there is continuity (zero ohms) or no continuity (infinite resistance) and just about any multi-meter can do that. You won't need a highly accurate continuity measurement unless you are measuring/replacing components on printed circuit cards.

You won't likely be testing any diodes on an automobile, either. Particularly if it's an older or simpler model of automobile.
 
Measuring current in a traditional vehicle, you'll need to have clamp on access, for both moderate and high currents. With electric vehicles, you'll have to consult the manufacturers recommended practice and test equipment.
 
You may not be able to disconnect wiring for trouble shooting, so how would you measure current
my brother repair old car and convert into a new one that's why I need these, he knows all these thing very well the truth is I want to gift him a meter of all purpose.
