Resistance is open between those same two pins in the voltage divider resistor network.
Do you have a 10M ohm resistor that you can solder like in the other thread to see if the meter works?
If not 10M, try a 1M ohm. The values will be off, but we are just testing it to see if there is any other damage.
I have a 1M resistor but it's a very fine resistor for hifi audio... I don't want to waste it. Will need to buy some for this test.
The $40 dollar multimeter is a mexican distributed made in china unit, it's a Truper model MUT-39. Not accurate at all... like 1% of error in voltage readings. But hey, it does the work, and I just finished measuring the amp that killed my beloved Fluke. This cheapo did it like nothing, felt like measuring potatos... Lol.
After this experience no more flukes for me I guess... way too expensive for this kind of failure. My next multimeter it's gonna be a Hioki
...or maybe you guys can suggest me some good ones?
