  • Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Ontario GTA West area meetup is planned for Saturday April 26th at Greasemonkeys shop in Aylmer Ontario. If you are interested and haven’t signed up yet, click here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area. Don’t be shy, sign up and come, or plan your own meetup!

Tool Alligator clips for Fluke 77iii

Tool
If anybody wants a hot tip on meters…. Fluke is THE BEST undoubtedly, no argument, at all. Accessories, everything, the best. But you pay for it like crazy.

There’s a brand of meter, “Brymen” that is manufactured in Taiwan…..

You can get your hands on those for ALOT less than fluke, and the quality and functionality will not dissapoint you.

They even have some functions fluke does not offer or only offers on very high end meters…..

These are not cheap meters, so don’t look them up and expect to pay 50$.

These are very good industrial quality meters suitable for professional use, and for a comparable fluke meter you’ll pay about a third ish.

They have proper input protection and are all CSA rated with CAT ratings.

They also come with alligator clips, and their leads are silicone and very satisfactory in quality.

Also interchangeable with fluke leads ;)


I have read similar comments on the EEVBLOG forum, if I ever need another DMM I would very likely order a Brymen they are very highly regarded.

There are so many unsafe DMMs with fake ratings it's just scary.
 
There are a lot of things Queale/Interior may not have, but they have been the best (only?) local-ish place I have found for shrink wrap tubing other than in pre-cut short pieces.
 
The first thing I notice in the first several minutes of the video is that the Brymen without even leads connected shows > 0 . And it wobbles. Mind you, I have cheap multimeters, and they are "good enough" for what I do, but... gotta wonder. Now I'll go watch the rest of the video.

This is normal. It's what I call environmental noise. Really good meters have extremely high input impedance so they don't affect the circuit they are connected to. That means the leads will develop some stray voltage levels from the environment when they are floating. This should disappear when they are connected to a circuit.

The Fluke does not show this. Does that imply that the Fluke is less sensitive? There were no leads attached (which could act as antennas). None of my admittedly cheap meters do this. The best being a 1980's vintage B&K Precision.

Swamped by the input under test? Presumes that what is being measured is greater than the environmental noise?

Well for one thing the Brymen has an extra digit, if the Fluke had that extra digit it may well be flikering?

That being said, at one point I had a 6-1/2 digit GWInstek bench meter, there was nothing intrinsically wrong with it but compared to the other 6-1/2 digit Fluke and Agilent meters I have it sucked. One of the reasons it sucked was the noise floor, so the bottom two digits were near useless most of the time. Even if I didn't need to know the voltage to the nearest uV it just didn't instil confidence and was distracting so I sold it and picked up another tried and true 34401A. For meters like the 34401A they specify accuracy for various time windows, 24 hour, 90 day, 1 year etc. All three of my 34401a meters measure the same down to the last digit +/-1 lsb, year after year after year without being recalibrated. Interesting little fun fact the reference used for these meters gets more and more stable with time so a 20 year old meter will have a more stable calibration than a brand new one, even though the new ones are fitted with an "aged" reference when new.
