Steady State Image

Steady State Image

Perform the common setup in Quick Start Steps, then click Steady State to start. Continue with the steps below.

1. Hardware

   1. Set the Base Temp to 20 °C.
   2. Set Device ON Voltage to 5 V and Device OFF Voltage to 0 V.
      • Note: Microscope Settings are auto-filled from Project Manager (no need to reselect them).

2. Timing/Illumination

   1. Set Device On Time to 10.
   2. Set Image Averages to 50.
   3. Set the Duty Cycle to 50%.
   4. Auto-select the Brightness (%).

3. 3D Alignment – Load Ref

   1. Click Load Ref.
   2. Select the saved file from Calibration.
   3. Wait a few seconds until the selected region is focused and the Load Ref indicator turns green.
   4. Set the initial parameters for Focus Tolerance, Alignment %, and Vibration Filter. The indicator lights turn green when the image is in range.
      • Note: Increasing the Alignment % value and decreasing the Vibration Filter improves alignment accuracy.

4. Start Measurement

   1. Once setup is complete, click START Measurement to begin the measurement.
      • Note: the source document literally reads "to begin calibration" here; this appears to be a copy/paste artifact carried over from the Calibration section rather than a distinct step — flagged here for anyone updating this procedure against the vendor source.

5. Save Images

   1. After sufficient averaging time, the hot line should appear (a few seconds).
   2. Select a region on Thermal Image View to get the ROI Temperature Value. (Example in source: the middle of the green 5 µm x 500 µm band is selected.)
   3. Enter the estimated Thermoreflectance Coefficient (Cth) from the calibration to get a more accurate ROI Temperature.
   4. Under Save Images, check that the directory and "Save Path" name are correct.
   5. When ready to save the data, press Save Image.
      • Note: Save the image before stopping the measurement.
   6. To stop the measurement, click STOP MEASUREMENT, or click File > Quit.

   Note on source step numbering: the vendor source labels both "Click START Measurement" and "Save Images" as step "4" in this section. They are presented here as steps 4 and 5, in the order they appear in the source, for clarity.
