Just checking specification of AVO Megger M8037 multimeter, it refreshing analog bar 120/sec fro DC and ohm.  Its way ahead of comeptition...

Anybody know more about this company and its multimeters?

Thanks :D

I bet that you love comparisons , but here you fall in a trap.

The human eye , like the one that I have , actually I have two ,
it needs 25 frames per second so to detect an smooth motion .
Now what it will happen , if the projection of 40 refreshes per second ( of my Fluke 28II ) or the 100 refreshes per second,
are detectable from your eyes ,  this is an subject that I have not explore .

But you can , if you search for it , as subject .

AVO were a very much respected company in the days of large analogue multimeters. Under the name AVO-Megger they also have a good reputation for well built and accurate equipment.

I own the 7029 as a back-up to my Fluke 87 III and I can advise that it is a very well built, solid, and accurate meter (within it's specification that is). Make sure it's specification and facilities meet your needs. I like the meter and for the price I paid, GBP30 for a 'new old stock' unit, I am very pleased with it.

When comparing it to my AVO-Megger B131 LCR meter, I would suggest that they are from the same manufacturer and I understand the B131 is in fact an 'Escort' design rebadged by AVO-Megger and TENMA.

Please be aware that AVO-Megger cannot supply schematics or spare parts for the 7000 series meters as they are not 'in-house' products.

anything flickering will make you headache (if you are sensitive guy :D), thats what i read and remember long time ago. anything faster than 25-30fps, you wont notice the transition, but you'll wonder the next morning why you have a headache when staring at something like monitor, screen etc. our brain will have a harder time "re-synching" to faster refresh rate, but not so fast, something like 30-75Hz iirc. Cheers mate, happy chinese new year ;)

PetrosA:
It sounds like there might be some confusion between updating the values and refreshing the LCD. I suspect the 120 times/sec DC/Ohm "refresh" is actually about the reading itself rather than the screen. A fast update speed will make it possible to detect spikes, dips etc. that a slower update speed might miss.
