what multimeter do not need to be collaborate

I want to know how can you tell when you need to collaborate a Multimemter. If so How do you do it and how do you get it more accurate and reliable measurements.

Which one is the good multimeter to get that can collaborate on it own or is that have a built in collaborate button.

I see that the fluke brand is good.


thanks spiderman. This collaborate is driving me nuts. I see them doing on youtube and stuff. lot of them don't know what they are doing. So I asking here thanks.

I think by "collaberate" you mean "calibrate". Virtually all multimeters sold today are more than accurate enough for use when diagnosing computer or electrical problems. For most there is no calibration necessary or even possible. I must admit I did find one cheap meter that gave false readings, however it was due to it being defective rather than just being inaccurate. Scott.

Maybe it just something you never knew about.

I know all about it. <g> Note that as I stated earlier it is not necessary to calibrate multimeters used in the scope of troubleshooting or repairing PCs. Scott.

Whether a meter is auto-ranging or not has nothing to do with its accuracy. Scott.

The reviews seem to be mixed on that one. I'd recommend Fluke multimeters if you really want the best. They introduced the the world's first successful hand-held DMM (Digital MultiMeter) back in 1977. Scott.

The reason I said this one was that it came with a 1 hour dvd on how to use the meter.




Maybe in your next upgrading and repairing pc you should do a DVD video part on how to use a multimeters. I understand a cheap meter will do for fixing computers. But we don't want to go so cheap that we could get fry there should be some safety in the meter so you don't get hurt.

I said I had good luck with CenTech tools in general, however I don't have one of their multimeters.

In the 14th edition DVD segment on Testing Power Supplies I demonstrate using a Fluke 85 III multimeter.

It is more convenient.

I have detailed segments showing how to use a multimeter to test and troubleshoot power supplies in the 14th and 22nd edition DVDs.

It seems unnecessary but I haven't had a chance to use one yet. Scott.

I maybe have found a good meter as good as a fluke... what do you think. yeah I know it's not auto-range but it does seem to be right on. I guess I will use it and see how it does and i'll get back to let you know on here and how good it is.

When I test the outlet it says 120.8 so it about right on.

But when I tested the dell AC adapter it shows 19.45 on the adapter it says on the block 19.5 DCV so is this OK reading 19.45 DCV

OK now you're making me laugh. <g> However while it may not be anywhere close to a Fluke it is no doubt good enough for servicing PCs. Scott.

so is the 19.45V is that close enough to 9.5 volts or should I just the heck with this metter and get a $900.00 or a 10,000.00 fluke...

for $10,000.00 fluke will need a very sex voice reading the numbers back and so on....

The DVDs are well worth the price of the books. The 14th ed. video is particularly good. Scott.

how trustworthy are the radioshack pocket digital multmeter model 22-820

I got one before raidoshack closed here about 2 years ago....
the only thing I don't like is the leads are attach to the meter.

but I am going to get a fluke and have one of those cheap meters just to test the batteries like the cmos and so on.
