The table gives the milllivolt readings for differential temperature.
(a) for ambient temp = 15 degree C, the the Thermal EMF (@15) = 0.762 mV (From Table Column 10, 5)
Now, Total Voltage = 4.45 + 0.762 = 5.212 mV
And the Corresponding Hot Junction Temp = 99 degree C (From Table 90, 9)
(b) for ambient temp = 25 degree C, the the Thermal EMF (@25) = 1.277mV (From Table Column 20, 5)
Now, Total Voltage = 1.277 - 2.17 = -0.893 mV
And the Corresponding Hot Junction Temp = -18 degree C (From Table -10, -8)
(c) for ambient temp = -10 degree C, the the Thermal EMF (@-10) = -0.501V (From Table Column -10, 0)
Now, Total Voltage = 5.34 - 0.501 = 4.839 mV
And the Corresponding Hot Junction Temp = 92 degree C (From Table 90, 2)
