Figure 1 MesureNet workstation Control panel Instruction for Initializing the MeasureNet Workstation to Record a Thermogram 1. Press the On/Off button to turn on the MeasureNet workstation (Figure 1). 2. Press Main Menu , and then press F2 Temperature , next press F1 Temperature vs. Time . 3. Half fill a 150-mL beaker with ice and water. Press Calibrate to calibrate the temperature probe (Figure 1). When prompted, enter 0.0 ºC as the actual temperature of the constant temperature of the constant temperature bath (ice water). Press Enter . Insert the temperature probe in the ice water. Swirl the temperature probe until the temperature approaches and stabilizes near 0 ºC ( it may not read exactly 0 ºC ). Press Enter . Remove the temperature probe from the ice water bath.

Unformatted text preview: X to Y . An * marks the parameter selected to change any given time. The Y axis is for temperature. Set the temperature 2-3 ºC below the initial temperature of the substance that the probe is inserted into. Press Enter . 5. Set the max temperature 2-3 ºC above the expected final temperature. Press Enter . 6. For example, to calibrate a Styrofoam cup calorimeter, the min temperature should be set to 15-18 ºC, and the max temperature should be set to 70-75 ºC. 7. The X axis is for time. Set scan parameters from 0 seconds ( min ) to 250 seconds ( max ). This should be sufficient time for most experiments that require thermograms. (If the experiments is completed before 250 seconds elapses, press Stop at any time to end the experiment). 8. When all parameters are entered, press Display to accept all values. The MeasureNet workstation is now ready to record a thermogram....
