As for the example taken before, if the probe code is 227, use table 02.
The value of the measurement in points is 2802.4. It falls in the extreme values of the fifth
slope, thus the coefficients to take to linearise the measurement are :
a = 0.001893 and
The time separating two readouts is limited by the rate of the instrument which is 20ms for a
rapid measurement.
