4.5 Glass fibre filter circle
Glass fibre filter circles ensure that liquid samples are evenly spread on the sample pan and prevent the
combustion of solids.
The glass fibre filter circle has the following advantages:
- even spreading due to capillary action
- no formation of drops
- quick evaporation due to larger surface
4.6 Practical advice
Before starting the measurement, place the sample pan and, if appropriate, the glass fibre filter on the
pan retainer and tare it to make sure that only the weight of your sample is assessed.
If you carry out several consecutive measurements, keep in mind that the temperature from the previous
measurement still obtains in the measuring chamber and that evaporation already takes place when the
cover is closed. This might affect the measuring results.
Therefore, you must either allow some time for the drying chamber to cool down or accept the deviations
and start the next measurement as soon as possible.
5 Operation
5.1 Measurement
The moisture balance saves the drying parameters last used after switching off and back on. These are
shown in the display.
Prepare the sample and place it in the drying chamber. You can now start the measurement by pressing
the
key.
After the measurement, the measured values will be available until they are deleted. You can use the
key to switch between the
weight indication / dry matter indication in %
and the
indication of
the moisture content in %
during and after the measurement. After the measurement, the measurement
values last determined must be deleted from the memory. To do so, press the
key.
ATTENTION:
Before placing the next sample on the sample pan, make sure that the display shows 0.0 g
respectively 0.00 g. If this is not the case, press the
key.
If, however, different drying parameters are necessary due to the different samples, you can use up to 16
memory locations. You can save the selected heat-up mode / termination criterion / drying temperature,
as well as the drying time if necessary, to each of the memory locations.
ATTENTION:
Do not touch the halogen lamps or the cover during the measurement as this can cause severe
burns.
After the measurement, let the sample cool down before touching it.
