FIXED ! - Brymen BM869S rejecting fresh 9V batteries.

It's not the most robust meter I have looked at

So what meter is more robust? Radioshack? Keysight? Fluke?

i managed to find the little bastard responsible for the current leak. it was a small diode

Hello rob77 and all eevblog members !!!
My name is Matias and I live in Argentina. My english is really bad !!! Please sorry.
6 / 8 month ago I bought one Brymen BM869s multimeter. For more or less 2 / 3 weeks I used the multimeter with the low battery icon on the screen.
Yesterday I replaced the battery for a new one (Energizer) and now the multimeter screen only show "InErr" and the buzzer give an alarm warning.
This problem is in all meter modes EXCEPT in "TEMP" and "A - mA" modes (Where the test leads must be located on the left connection ports and not on the most common used).

I think that this is the same problem that rob77 had and now I have it too. The question is if you can provide information about the diode type and it characteristics to try to buy locally the same diode. I know that I will not find here in Argentina the same SMD diode because is really hard to find locally SMD components. I will try but, if not find, I will need to use and standard hole diode adapted.

I'm NOT an Electronic technician, I'm just a handyman with many expectations, desire to do things and limited resources ($$). I hope that you can help me.

Thanks a lot !!!!

Matias.

Could you tell me the specification of the diode at D13?

..actually a brief update since I posted... I had dirt from a wasp nest in the left 'A' input!

I had been in touch with Brymen and they responded to me within 4 hours with a suggestion to clean both inputs.  They were quick to help and spot on with their suggestions. I cleaned the inside of the input plug with a cotton bud and solved the issue.

Here is their suggested solution in case other users have the same issue:

The problem of your unit might come from its A or mA/uA input terminal. Please rotate knob switch to mA/A function position.   
 
1. If mA function is displayed (not InErr anymore), then the problem might come from uA/mA input terminal. uA/mA input terminal is with two contact metal plates inside. Something might fall in between them and affect their impedance. To clean uA/mA input terminal might be able to fix its problem. 
 
2. If A function is displayed (not InErr anymore), then the problem might come from A input terminal. A input terminal is with two contact metal plates inside. Something might fall in between them and affect their impedance. To clean A input terminal might be able to fix its problem.
 
3. If InErr is still displayed, then to clean both A & uA/mA input terminals might be able to fix its problem.
