Title: Brymen 869S OL on AC Only
Post by: dkupers on December 26, 2019, 01:57:30 pm

Guys,

edit: link updated

got the same problem as this guy:
https://www.eevblog.com/forum/repair/brymen-bm869s-ol-problem-with-ac-measument/msg1936180/#msg1936180 (https://www.eevblog.com/forum/repair/brymen-bm869s-ol-problem-with-ac-measument/msg1936180/#msg1936180)
My meter didn't have a rough life, the meter is only used occasionaly.
Unfortunately, that post has not been updated for a long time.

In calibration mode, when trying to calibrate the 2.5ACV, the 'live input' shows 4.19430V, opposed to the 'real' input in other (non-AC) input modes.

Anyone knows a solution for the problem?

Greetings,
Dethmer.

the thread is not valid 404 not found ??

You tried to calibrate the meter ???  do you have to official brymen calibration procedures ???

I had one for my 857s,  but it had errors in it and was not an official brymen document

Ask Brymen under an NDA  "non disclosure agreement",  they did provide me the right infos ...

Thanks coro.

Calibration is just entering the calibration mode by a switch combination and applying the voltage the meter indicaties.

Fortunately, the multimeter is still under warranty (found the invoice). Sent it to the shop I bought it from.
