Hi. Post #141. When the meter is switched to resistance mode and no probes are touching anything, the reading on the screen is "0.L MΩ". That's what I meant when I said zero resistance. Apologies if this is confusing you. When I have had readings before that are non-zero, the L disappears off the screen. Unfortunately the manual does not specify anything about what the L means...

UG5 pin7 voltage reading is 2.3V

Post #142
UG5 pins
2 - 2.4V
3 - 2.3V
6 - 2.5V

Thanks.

Colin.
