Measuring Pt-100 Temperature Sensor

ndix C. CR3000 Pro

Example C measures the Pt-100 senso te perature of the C R4.

gram requ s four different measure the four radi ion

ts, one current excitation channel, and one differential channel for Pt-100

measurement. The program measures the sensors every 1 second, performs the

online processing of the data, and stores the following processed data to a data

nr4_data once every 60 minutes. It also stores the raw time-series

ata from CNR4 to data table called cnr4_ts.
