CALC:TEMP:THER? 0.0617,5.0

Ω

converts 

an array of thermocouple output voltages into temperatures. The thermocouple type 
is specified in the <type> parameter and the isothermal reference temperature is 
specified in the <thr_temp> parameter. The temperature values are returned in ºC.

This command is available with VXIplug&play driver revision A.01.09 or later 
(revision A.01.06 or later of hpe1422_32.dll).

•

The <volt_array> is an IEEE-488.2 definite length block of double (float64) 

values, which is the array of thermocouple output voltages.

•

Returned Value: array of temperatures in ºC. The data type is

 

double (float64).
