1.3.3 Commands for thermocouple measurements
AM
(AMbient temperature reference)
AM
Note: This command applies only to IMP types 1A, 1C, 1E, 1H and 1J.
Function: Instructs the IMP to use the ambient temperature as a reference for those channels set for
thermocouple measurement. The ambient temperature is sensed by a thermistor in the IMP
connector block. This is the default (power-up) condition.
To set an external temperature reference, use the TE command.
Response: None.

TE t
Where: t is the external reference junction temperature, defined by an IEEE 754 floating-point number
in the range:

Note: This command applies only to IMP types 1A, 1C, 1E, 1H and 1J.
Function: Sets the value of the external temperature reference into the IMP. For use only when an
external reference

junction is to be used. The units used for temperature results and
references are set by the UN command.
Response: None.

Historically, called the ‘cold’ junction. Now known more accurately as the reference junction. Similarly, the ‘hot’ junction is now
known as the measurement junction.
