Re: Best Multimeter?
I don't think there is any standardization in this area. I have a $17 craftsman that does most what I need for ebike purposes. Functions that I use are Voltage, Resistance and Continuity.majornelson wrote:What are the preferred multimeters those in the forum use?

It can do 600V, 200mA DC or 10A DC (depending on the plug you choose), 500V DC/AC continuity.
I couldn't find it for a couple weeks, so I went to Fry's and spent $20 on a different one that does similar stuff and it has worked well enough for ebikes. Spend around $20 on a digital and it should be good enough for ebike needs.
Get a Cycle Analyst and a Multimeter, you're still a noob if you don't have at least one of each.

Re: Best Multimeter?
If you can swing it, buy the best Fluke you can. It will last many lifetimes and holds calibration well. After 25 years or so the displays fluke out because the polymer "zebra strip" dries out, but you can 2nd source those parts now to keep them running about forever.

Try eBay. Fluke 77 is a cheaper older design. Mine has been very reliable. Better versions out, but plenty good for ebike, and most uses.

Re: Best Multimeter?
A Fluke 115 would be the "best entry level" multimeter. At $160 its actualy cheap for what you get.
The "Best" is probably the Fluke 289. They're around $700. You don't need it, unless you plan to work on the Hadron collider, or something with higher specs than NASA would ever dream of . (I think it was a Fluke 115 I used when we build cameras for NASA.)
But you don't need best unless you're planning use Lipo, or build your own controller, or something where precision and accuracy matter a great deal.
Really what you need is a $30 from Home Depot, or someplace like that. Avoid Radio Shi... Shack.

Re: Best Multimeter?
My electrical expertise is pretty limited... would something like this be any good?
http://www.amazon.com/Equus-3320-Auto-R ... pd_cp_hi_1
I checked the Fluke 117 and it's roughly $135 on Amazon. The Equus is about $17 but is it junk? My use would be troubleshooting and testing on all things ebike.

Re: Best Multimeter?
It won't need to be expensive. A continuity sounder is an absolute must. Look for a 20 amp ac/dc currant range and some nice leads. Accessories like crocodile clips and a shock proof jacket. A diode and transistor test are less useful. You can test them enough just switched to continuity.
I got a nice looking one in a yellow rubber jacket that seemed ideal till it played a cheesy tune for continuity. Thing belonged in a joke shop.
Arh, you have posted again. The one in the link seems ok.

I've used the Fluke 87 V for some years now and its managed to pay for itself over time. Not sure how they are today but the Micronta digital meters used to be a good buy.YMMV
Stable:

12 Catrike Expedition (Candy Purple), 18s32Ah Lipo batt. Lyen 18 FET low RDS controller, C'Lyte HS3540 hub motor, CA-SA, Mueller Bros. Windwrap XT fairing, Terra Cycle Cargo Monster extension. Still evolving, should be interesting by next Spring.

Re: Best Multimeter?
I started with a Micronta, now i have a Fluke 116..
the biggest difference is the speed of the readout, when i was testing 72v nimh i had to check 60 cells multiple times per charge cycle, the difference between getting a number in 1 second vs 3 seconds adds up. lol..
but seriously, a 20$ unit is good enough as a starter unit, good enough for most jobs.. and accurate enough for troubleshooting basic ebike stuff.

Re: Best Multimeter?
Any meter is better than no meter.
That said, jut be careful with $20 meters if you use them some day on your mains to the house. I read a report where an electrician got killed on, I think it was like 277/480 volt 3 phase system. The meter did not have enough creep protection on the PCB and it arced over internal to the meter, the internal fuse was not rated to interrupt the plasma ball in his hand. (If you ever take a Fluke apart the fuses are huge in them!) The resultant arc and plasma ball killed him. Note I am not an alarmist, just know the limitations of lower priced meters if you use them above 220 volts where the source can source kilo amps.

Re: Best Multimeter?
The one thing to watch out for on cheap meters, are the cheap probes that come with them.
I have had the wire break from the tip, thus indicating no voltage!! Than the big surprise !!

Re: Best Multimeter?
I have a older fluke and they are quality. Lately I mostly grab my relatively cheap clamp meter when doing most anything. It has the added benefit of ac current measurements and quickly tells you if you have a dangerous at hand live wire without fuss. Also it acts like a holder when working in the rafters and will hold it for you on any nail, pipe or wire while your probing around with the leads and have both hands busy. Will not do dc amps but some more expensive ones do.

Re: Best Multimeter?
I just picked up a right cheap meter that does loads. £25 on my doorstep got me...
Volts up too 1000 ac/dc manual or auto ranging
Amps up to0 20 ac/dc
Resistance too 60M
Capacitance 2000uf
Frequency to 60megs (or duty)
Diodes and transistor hfe
Temperature -40 too 1000c
Null button for work along cell groups without moving the neg, or just to zero leads.
min/max
Bargraph
Rubber holster with stand/hanger
Fairly nice leads with caps that a pencil sharpener can trim down to reveal a legal amount of metal.
All ranges will take 250vac by mistake.
I was looking at flukes tbh, but the 101 was to basic and the one's just above it only read 100uf which is useless to me as an electrician. There not good for electronics either as they put out too much power when testing resistance. I can't quite believe how much I got for peanuts with this meter.

Re: Best Multimeter?
Professional technician it’s a no-brainer to buy a Pro meter like Fluke.
However, even the best meter can and will drift outta calibration and/or suffer ill-effects from a dead internal battery, operator errors, etc.
For novices getting into this, south of $20 is much less daunting than north of $100. And much like eBikes, it will always be better to have more than one on hand in order to setup more complex tests or simply verify that another meter is in the ballpark.
Maybe you'll find you need and/or want a higher quality meter? If so, buy it and then also have a $20 spare meter to provide a 2nd opinion when readings fail to make sense.
Personally speaking, you’re much better off directing significant budget toward assembling good quality meter test leads. Heat shrink/gun, connector crimping tools, bulk wire, etc. All of that stuff which comes in handy, time and time again.
Here's a sub $20 cheapo which has been an absolute joy to use for over 10 years. It's helped verify dead batteries from more than few Fluke meters, LOL....

Re: Best Multimeter?
Thanks for the warning Bigmoose - hadn't realised something like that could happen. I suspect they're probably a safety standard we ought to check a meter conforms to.
Another upside to a cheapish meter is that it's not a lot of money lost when you do bad things to it. Like forgetting to change back from the current setting before checking the mains voltage... Or accidentally check continuity or resistance on a live circuit. Or accidentally use the 200mA current setting on a 50A circuit. Stupid things that I've done several times and I'd hate to think I might have ruined a nice Fluke meter in doing so.
Another vote for buying good quality leads

I do have a professional meter, but it don't have a single function I can use on the bike. Typically speaking, pro meters are aimed at a narrow field. The bike is perhaps best serviced by an auto-meter of some sort. Capable of reading high currant but still be used for electronics. That was my brief.
I find having a few helps with calibration.
