R For the additional values referred to in NOTE 1 above see R (Ref. Fig. 309) R The value on the vertical scale is the additional value of capacitance in pF R to be added to the MEAN THEORETICAL (MTV) when the fuel tanks are wet. R R EXAMPLE (Smiths FQIS) R R The MTV for Probe 21QT1 is 70.29pF. R R Immediately after draining an additional 0.25pF is to be added to this R value, (from slope 1). R 70.29 + 0.25 = 70.54pF R R After one hour this additional value will have reduced to 0.105pF, (from R slope 2). R 70.29 + 0.105 = 70.395pF R
