If you are determining fuel moisture with the Delmhorst J-2000 or similar handheld moisture meter, take 3 pieces of fuel at random
from the stock used for each test and measure each in three places along its length. Enter the results in the gray spaces below. The
worksheet will automatically calculate average moisture content on a dry and wet basis.
If you are using another means to determine fuel moisture, ignore this worksheet and enter the moisture in the proper space on each
Test's data form.

Instrument reading
(% dry basis)The Delmhorst J-2000 moisture analyzermeasures fuel moisture on a dry basis. Tofind moisture on a wet basis, use the following
equation:
This spreadsheet does this calculationautomatically if a value is entered in the dry-basis space. Output requires moisture contenton a wet basis, so the conversion is veryimportant.
