I told my friends I could teach them to be funny, but they all just laughed at me.

I don't have this meter but image search suggests that it is available under at least 3 different brand and model numbers.

Have a look at one of Big Clive's videos - there may be enough info in it for your purposes (whatever they are)

Good morning; thank you for your kindness! I have already watched this video, and I sent my request by email to the owner of this multimeter, but since Sunday, I have not heard back...Cdt :palm:

Good morning; I made progress this afternoon in my troubleshooting; and the culprit is D17! (zener I think; I'm posting the photo), can someone do tests on their multimeter to find its value?? And also can you tell me how much power it consumes when starting up? Thanks in advance
