9. Next, take the sinker out of the hook, put the beaker with liquid on the beaker’s basis (the
beaker cannot touch the hook), gently hang the sinker on the hook providing that it is totally
immersed in the tested liquid (sample mass determination in liquid) and confirm the
indication when stable
.
10. On the second confirmation of the indication, the program automatically calculates and
displays the tested solid object density. At the same time, a report on the measurement is
sent to a selected port of a printer.
An example report:
The report may be reprinted upon pressing button. In order to finish, press button. The
software returns to the main window of the mode and a next measurement can be performed. The
balance operates with previously set parameter values (liquid, temperature) thus shortening time
needed for the exact measurement.
13. ANIMAL WEIGHING
Animal weighing is a working mode allowing reliable determination of mass of weighed objects in
motion. In principle, this type of object generates unstable measurement, thus it requires using a
different filtering method of measurement signal.
Apart from standard settings for this mode (i.e. weighing mode settings) some additional parameters
have been designed to describe operation of the mode.
Additional settings list:
AVERAGING TIME Amount of time during which recorded measurement results are
analyzed. Obtained data is used to determine average measurement result.
THRESHOLD - It is a value expressed in mass measuring units. To start measurement, the
indication value has to exceed the set threshold value.
