Type k will work up till it melts ( and then a little more until the drop falls off), and even if the response is not linear it is at least monotonic. I have often repaired them with an acetylene torch to weld the wires back together, or to weld them back to the steel plate they were measuring. The insulation almost invariably was the limiting item, unless you used a filled magnesia tube with a steel jacket, or a sintered ceramic sleeve. Come back to one on a heater and find the first few cm are bare wire, the glass fibre having flaked off, but it still works as long as the bare wires do not touch. If they did the controller would cook the heater trying to get it to setpoint.

After opening up my WD1 model, I found that the main processing board already has a MAX232 chip on it. I guess that the M model only contains an additional USB to RS232 board.

When I have time, i will try and connect a normal RS232 cable to the MAX232 that is already in my non-M model  ;)
Been a few years since I opened it, so I don't recall exactly what was on the boards (don't recall there was much to it; basically a PIC on the LCD board and power board IIRC).

But you've piqued my curiosity, and I may have to break it open soon.  ;D

it says for me cp2102 usb to uart bridge controller, as for the windows driver, which failes to install on my laptop just like the fluke ir cable driver... i love original microsoft products...
