Figure 2.27 Zeroing-Out the Meter Lever
Replace the outer screw and the calibration of the water detector is
completed. You are ready to begin the undissolved water test procedure.
First collect a sample and prepare the stainless steel monitor.
NOTE: Normal sample volume is 500 milliliters (17.0 ounces) of fuel, however, if
the reading is off--higher than normal--sample volumes maybe reduced to as low
as 100 milliliters (3.4 ounces), multiplying the reading number by 5 to obtain the
parts per million.
You may opt to perform this test prior to performing the API Gravity tests
since this fuel sample can be re-used and a smaller, less exacting amount of fuel is
required for the API Gravity tests.
