If the sensor temperature changes after calibration, and
the meter and sensor is not re-calibrated, then the following
additional linearity errors should be added to the linearity
figures in Tables 6a and 6b.

Figure 5 shows the typical uncertainty in making a relative
power measurement, using the same power meter channel
and the same power sensor to obtain the reference and the
measured values. It also assumes that negligible change in
frequency and mismatch error occurs when transitioning
from the power level used as the reference to the power
level measured.
