TH2830 vs TH2832

Of course some different valued capacitors could also affect oscillator/filtering operations and be hard to notice, but different firmware/gateware/calibration data is more likely.

I agree. The interesting stuff happens in the digital domain where the Altera chip likely does the signal generation & acquisition and the LPC1788 microcontroller uses software to do the heavy lifting. There really is no need for the hardware to be different at all. And maybe the software is the same as well as it is much easier to have a single firmware image for all devices. So in the end the difference may be a component strapping (somewhere around the LPC1788) or a setting in the FRAM / flash.

KungFuJosh:
Firmware version is shown on startup. Both of our meters say ver1.0 but have different copyright dates. I assume the copyright date is reference to the firmware.

Both main boards show "TH2830-MAIN VER1.9..."

nctnico:
Time to dump the contents of the flashes and (if possible) the LPC1788... Or find firmwage images so these can be compared.

coromonadalix:
their chinees site  seem to give more files, haven't seen a fw upgrade ???

I don't know how to do that.

I do have a TH2830 hex firmware file. I haven't had any luck finding the TH2832 firmware yet to compare them.
