7.3.7 Thermocouples
Thermocouples are active transducers. To perform measurements with ther
mocouples you will need the ML801B amplifier module as well as connec
tion board AP809. The temperature cold junction is built into the AP809. The
amplifier module performs cold-spot compensation and linearization for the
thermocouple type K.
If you selected 'Thermocouples' as the operating mode and °C or °F as the
unit, the corresponding temperature display will be in the selected unit. If
you select
operating mode "75 mV", you will have the output voltage of
the thermocouple directly (without linearization and cold-spot
compensation).
