Does my dataTaker support PT1000 RTDs?
PT1000 uses a small Platinum resistor that is sensitive to temperature change. It has a resistance of 1000 Ohms at 0 deg C. The default settings in the dataTaker assumes 100 Ohms at 0 Deg C. This can be changed with the resistance at 0 Deg C being entered as a channel option. Another issue to consider is the excitation current used to measure the RTD. On the DT80 and DT5/6xx range of data loggers, the excitation current used is selected using a channel option (either “I” for 250/213uA or “II” for 2.5mA). The default current source (II – 2.5mA) is good for PT100 devices, but too large for PT1000 devices. For PT1000 devices the smaller (I – 250/213uA) current source should be used.
