• The instrument will tare (zero out) the
pan. This will occur instantly if the lid
has been closed and the balance is
stable.
• Open the lid and quickly load the
sample, taking care to evenly
distribute it across the entire pan
surface in a thin layer to get the fastest
and most accurate results.
While loading the sample, the weight
is displayed graphically with the
acceptable target window in green
and in grams at the screen bottom.
Add sample so that the sample weight
is centered in the graph; an audible
signal indicates when the sample
weight is acceptable.
Once the desired amount has been added, the pan can be removed from the test
chamber to evenly distribute the sample. The sample should be distributed over the
surface of the pan by gentle shaking or tapping, or for very viscous samples,
spreading with a spoon or knife. An even layer of sample across the pan will reduce
test times and increase precision of results.
To load difficult samples more easily, remove the sample pan from the instrument
after the correct amount of sample has been placed on the pan, place the filled pan on
a level work surface, spread the sample with a small flat brush or spatula (depending
on the consistency of the sample), and then replace the loaded sample pan on the pan
support. Do not spread granular products with a spoon as the particles compress
even under gentle pressure affecting test times and results.
Transport samples in an airtight container to prevent moisture gain or loss through
contact with air.
If performing WEIGHT tests: The weight test simulates moisture loss with the removal
of one of two known weights, and is used to verify the balance is responding properly.
Select (Factory) WEIGHT as the Test Program to perform the weight test, then wait
approximately three minutes for the chamber to heat to 80 °C before starting the test.
Instead of adding sample material to be tested, carefully place both the included
5-gram and 3-gram weights near the center of the sample pan when prompted.
