(to be added)

Writing a data logger program

1., 2. Proceed as in the previous example to set up the program using SCWin following steps

one and two above. Choose an appropriate name for the new program.

3. From the home page press “Sensors”. Under “Available Programs” open the “Generic

Measurements” folder. Select “Full Bridge”, the transducer is of this type of circuit, and

press the red arrow, or double click it (See Fig. 10). Set the “Range of Sensor Voltage”

to +/- 250 mv (See Fig. 11). Then click OK. The sensor should now be listed under

“Selected Sensors” on the left side of the screen. Again under available sensors, go to

temperature and select the Type T thermocouple as described previously. After the

thermocouple has been selected both sensors should be listed under “Selected Sensors”.
