5.3 Adjustment / calibration
The moisture analyser consists of a weighing unit and a drying chamber. The moisture measurement is
carried out on the basis of the weight loss. This can be easily reproduced by a rule of three.
ATTENTION:
The moisture analysers of the PCE-MA series have a higher weighing resolution than the
one indicated. The moisture balance uses the higher resolution which is invisible to the user for
calculation. This can result in deviations after the decimal point when trying to reproduce the result.
The weighing unit can be adjusted by means of a 100 g external test weight (min. M1). Special care must
be taken when positioning the scales (as little vibration as possible and balanced by means of the level).
The adjustment of the weighing unit should only be carried out after a heat-up time of approx. 30 minutes.
To do so, press and hold the
key for approx.. 6 seconds. “-CAL-” will be displayed.
After the “-CAL-” indication, “100.00 g” will flash.
Now place the 100 g calibration weight in the middle of the weighing platform. The indication will change
from “100.00 g” to “=====”.
When the indication changes from “=====” back to “100.00 g”, remove the weight from the weighing
platform. After this, the display will show “=====” again and change to “0.00 g” automatically.
The adjustment of the balance is now finished.
