plazma, I'm not sure you can access the other pushbutton switch lines on AN8008. Let us know how it's going. When I looked at the AN8008 circuit, the pushbuttons go to GND instead of a matrix. The DMM IC/MCU supports a scanned 2x3 matrix for up to 6 pushbuttons + BL to GND for total 7 buttons as per pic. The AN8008 firmware might still allow the other pushbuttons but I could not see one or two MCU lines for them. RANGE/BL goes to GND. Is PT1.0? Not sure about PT3.7 I did not see it. SEL/HOLD goes to GND; Is PT3.5? Not sure about PT1.1 I did not see it. REL/RS232 and HOLD/Backlight we have PT1.5 from the EEPROM pin 5. |

Just got back home after travelling, my "AN8008" was a stupid plastic junk item and a BS Chinglish note - I'll be complaining to Amazon tomorrow I think. |

The manufacturers do not want to have to explain offset voltages and thermal voltages to complaining customers I guess. It would be great if there is a way to turn this dead zone off. --- End quote --- Yup, same with most of the Chinese digital panel meters, making them useless for many applications.... :( This is part of the reason I am making my own panel meter of sorts, for a power supply, using an arduino, a display, and the awesome INA226. mV resolution full-scale at 120Hz update rate on the slowest speed, and agrees within 3 counts of a keithley 2015 bench meter! |
