depth' value);
4. Retrieve the data from the logger;
5. Open the View statistics/Two-point calibration window;
6. Select the depth channel using the display cursor;
7. Select the raw data view using the Change data view button;

9. Set the fixed-point value of the bottom set of boxes to the actual depth
value used in step 3.
10. Use the cursor to select a range of readings that represent the 'at depth'
