APPLICATION <br />The calibration described in Section 3 is implemented as follows: <br />0 Obtain the temperature differential, AT (OC), from the TDS <br />• Compute T* using Eq. '1 with the measured temperature differential, AT, and the <br />temperature differentials ATd and AT, listed in Table 1. <br />• Determine the suction (W) in kPa corresponding to T* using Eq. 2 and the <br />parameters iV,, m, and n listed in Table 1. <br />
