it looks like version 57t has a boundary issue maybe - causing the low voltage on short to appear as a large negative value (not that this is going to matter in normal use, but I thought I'd bring it to your attention dc42)

If you are using my latest firmware 057t - dc42 then you can reprogram the thermistor resistance at 25 C and thermistor beta. See the checkin comment for details.
You can find 057t-dc42 and other revisions at [github.com]. From there, follow the link to the file you want, then click Raw to download it.

@groneorm, the release notes that describe setting the R25 and beta values are here: [github.com] (scroll down the readme until near the end)
Ray
- Implemented M301 (hot end PID parameters) and M304 (bed PID parameters) commands. Extended these commands to allow setting of thermistor resistance at 25C (R parameter) and thermistor beta (B parameter). A negative P parameter means don't use PID, use bang-bang control.
R C 100K 22.7C 39K 45.9 33K 50Did not find any multimeter atm so I couldn't confirm the exact R values. Resistor connected to HE wireloom.

Groneorm /KevM - dc42 has released a new firmware version which allow you to calibrate the temperatures using a 100k resistor for low temperatures and a 220ohm for high temperatures (though you could use other values along with the spreadsheet above) - please see this thread [forums.reprap.org]
