INSTRUMENT CALIBRATION CHECK:
Make sure that the container is empty and that the instrument displays zero. Place a significant
quantity of product in the container (at least 50% of the maximum quantity of product that is to be
weighed but in any case less than 9,999) and make sure that the instrument displays the correct value.
-
If there is a significant difference between the displayed value and effective amount ( greater
than 1-2% ) check that this is not caused by a mechanical fault and check the electrical connections
of the cell and the cell loading position.
-
If the difference is not significant but around 1-2 %, then proceed to CORRECTING
DISPLAYED WEIGHT FROM KEYBOARD.
CORRECTING DISPLAYED WEIGHT FROM KEYBOARD:
When the weight is displayed, press
. The display will show “CAL I”. Hold down the
key
and press ENTER. The display will show the weight value blinking. Use the
and
keys to
correct it and set the value of the real quantity loaded in the container. Press ENTER to confirm. The
display will show “CAL I “ for an instant, then the correct value will appear.
If the display shows " CAL l ", this means that incorrect values have been set for the
parameters “CELL” and “nU-U”. Repeat the calibration (see THEORETICAL
CALIBRATION) restoring the laboratory setting.
