Hello together,
I’m a beginner in using LabView and NI Hardware. I have to measure a lot of temperature values with the following configuration:
Thermocouples Typ L
SCXI 1300 and SCXI 1303 Terminal Blocks
SCXI 1100 Modules
SCXI 1000 and SCXI 1001 Chassis
PCI-MIO-16-E4 DAQ-Board
The Typ L thermocouples are not supported by the DAQmx. My first try was to created my own scale in a voltage task but then the cold junction temperature is not considered. Does anybody know how to implement a thermocouple Typ L? My idea was to read the voltage data from the built-in CJC Sensor in the SCXI 1303/1300 Terminal Blocks and add it to the voltage which I measured when using a normal voltage task. With the total voltage I can calculate the temperature with a polynomial for Typ L. Is this the right way? And how can I get the CJ-voltage?
Thanks in advance for helping!

I don't see type L as a valid type.

Typ L is not used anymore. It's an old plant I'm working with. Typ L is similar to Typ J.
Here is the reference table:
