EEV BM235 - Continuity Problem

[lazaj]

Hello,

I bought my EEV BM235 in 2017, since then no problems.
I haven't used it for a month, today I start using it and it seems to have a problem in continuity mode.
I tried several probes, change batteries ...

When I join the probes together, it show 4 Ohms and then the measurement slowly drops to 0.5 Ohms.
I did not have time to test the other functions.

Any advices.

Thanks.
