The TEM command is setup to give deg C readings from T thermocouples.

I need to log the temperature of something over time,

the HP3421A data acquisition unit has a TEMperature function, so I
thought I'd use that.
Does anyone know what sort of thermocouple I should be using with it. I
asusme I just connect said thermocouple to one of the inputs on the
scanner assembly (which seems to do cold-junction compensation).
Thanks in advance for any help

I should have added in my first message: it is possible to use
a different kind of thermocouple by tracing back the original voltage,
and do cold junction compensation in software for the actual kind of
thermocouple that you have. I believe there is even a small program
in BASIC, as well as the coefficients for conversion using polynomials,
in the original 3421 manual. I can dig it up if you want; let me know
which type of thermocouple you will be using.

Thanks for the information. I think I can find type T thermocouples in
the catalogues with no problem..
