Notes:1) Barometric correction is applied, but may not be applicable, if downhole zone is isolated.2) P(kPa) = [C.F.(Li-Lc)] - [Tk(Ti-Tc)] + [0.1(Bi-Bc)]

Where: L is B Unit readingT is Temperature readingB is Barometric Pressure reading i is the Initial Reading from the instrument calibration c is the Current Reading

3) Conversion mPa to meters water head = mPa x 101.99773
