B.2 Measuring thermocouples
The following program measures 20 thermocouples on a TEMP 120. This example uses
CDM_TCComp()
to measure both the reference thermistor and thermocouples.
'GRANITE 6 Datalogger
'This program sets CPI Address and Device Name on a TEMP 120 with serial
'number 1234 and uses the TEMP 120 to measure 20 Type-T thermocouples.
'Declare Variables and Units
