Multi Meter question

[gruntfuttock]

Hi Folks,

I need a multi meter that puts out no more than 0.2v when using the Ohmmeter. It also should be very accurate. What is the best around?

[WhiteD3]

Fluke are the best and the most expensive. They make an identical looking (but diff colour, Orange or red from memory) range called wattmaster (I think) but they're lower spec'd and the accuracy is a lot worse than the Fluke range.

What ever you get, read the spec and accuracy as this can be an issue at the lower end of the reading ranges.

Can I ask, why no more than 0.2V ?

I am a Horologer and as most multi meters run at 0.4v that is enough to give false readings on the small stuff I need to test:D

If all you want to measure is ohms, my suggestion is a low ohm meter, downside is all it reads is ohms, upside your not paying money for other functions on the multi meter.

This of course is only helpful if measuring low value ohms. I hope this is of some help.

Thanks,

but I also need to measure uA & vlotage.

I could by an machine specially made for the job for a meager $13000, but being a tight fisted deep pocketed person. Thats just out of the question

let me check in the office for you... my company does calibration of instruments to the levels you are talking about and they are notoriously tight fisted swiss guys.... but at a guess, I'd say they are using Hioki branded desktop gear.

Wow 13k, i dont think your arms have to be too short nor your pockets that long for that to hurt.

The only other thing I can think of is to hire the test equipment from such companies as tech rentals. Unfortunately this too will cost somewhat. Good luck in your search.

As mentioned before it is for horological use. Being suisse they will know just what you are talking about.

Just so that everybody knows what I am talking about,

Just to make things a bit clearer, here is some test sepcs.

I need something that can test
µA
MΩ
KΩ
As well as voltage
For example, Resistance of a coil 1.56 to 1.82 KΩ
Power consumption ≤ 0.35µA

Have a look at this

Or is that you already?:D

Nope that is not me. Interesting read though. They were talking about the accutron tuning fork watch and clocks. I want it for small quartz watches. Something about the size, 13mm X 15,15mm X 1.35mm.

As some stuff I will encounter is new stuff, and on the date sheet it is written, and I quote, "Ohmmeter with a test voltage higher than 0.4V is unsuitable, recommended vlotage 0.20V"

The NAWCC is American, so with some things electrical there can be differences. So as I am not a guru in this I prefer to stay within my own country to be safe.

here is the feedback from our calibration department, I was wrong in that the Hioki stuff they use is $20k+ per instrument, but based on the instruments they calibrate, the below linked items are the most stable/reliable at their price points - all are Fluke and off the shelf items locally (in Singapore). Up to you if you want to consider a quick cheap flight up here to buy one and take it back home on the savings or not, or to use the contact given below as a price comparison to what you can get in your location...

"I would recommend the following multimeters as below, that should be able to meet your friend’s requirements:

Many thanks EchiDna,
I will definatly do some homework before buying one. I cannot however fly to Singapore to buy one. The accountant might be rather upset.

Many many thanks to all who contributed to this subject and answered my questions

Thanks to all

They don't seem to have 8808a, but have the others.
