2) Save and provide a name for the DMM configuration for the scanning purposes (here, TEMP
is used).
3) Setup the scanlist
a. Add a scan step with a sweep phase that scans CH1_1 using the previously saved
configuration (e.g. CH1_1=TEMP)
b. The setup phase can be ignored for this example.
4) Initiate & Read
a. Initiate the scan
b. Read back the data
Use Thermistor as a Reference Junction
1) Set the DMM to measure temperature using the thermistor.
a. Set the DMM function to Temperature.
b. Set the transducer type to Thermistor.
c. Set the thermistor resistance to 10000 (the thermistor is 10 kΩ).
d. Set the isReferenceJunction parameter to True.
2) Save and provide a name for the DMM configuration for the scanning purposes.
3) Set the DMM to measure temperature using a Type K thermocouple (any thermocouple type
can be selected here, but Type K below).
a. Set the DMM function to Temperature.
b. Set the transducer type to Thermocouple.
c. Set the thermocouple type to Type K.
d. Set the reference type to External.
e. Set the isReferenceJunction parameter to False.
4) Save and provide a name for the DMM configuration for the scanning purposes.
5) Setup the scanlist
a. Add a scan step with a sweep phase that scans CH1_1 using the first saved configuration.
(e.g. CH1_1=RefJunction).
b. Add another scan step with a sweep phase that scans another channel (e.g.
CH1_2=TEMP).
c. The setup phase can be ignored for this example.
6) Initiate & Read
a. Initiate the scan
b. Read back the data
