Calibration
The fuel transducer supplied with the fuel f low
meter will provide readings at better than 5%
accuracy. Individual calibration will increase this
level of accuracy to better than 2% over a fuel
flow range of 10.0 to 120 litres per hour. Use the
following steps to calibrate your fuel flow m eter:
1. Reset the total log value to zero (see previous
page).
2. Use a known amount of fuel. The larger the

be.

and the fuel used indicated by the total log. If
these two totals are different the instrument
