For each step in Table 11:
1. Set the Product to the calibration set point shown in Table 11. Allow
35 minutes for stabilization.
2. Take the dew point measurement with the chilled mirror.
3. Take the temperature measurement with the 5611T probes. Calculate the
average of the 8 temperature measurements for each step and enter that as
each of the Temperature Readings in Table 11.
4. Use a relative humidity calculator to determine the relative humidity for that
test point.
