Sartorius XQ 6100 Installation And Operating Instructions Manual page 8

lf you wish to use a Container or if the weight display does not
indicate 0.00 g (or the equivalent with the weight unit of your
choice), press the tare control to zero the display.
Important Note
The small circle in the lower left-hand corner shows that the
scale has been exactly tared so the display reads "0."
Do not wait to replace worn dust covers.
Make sure that paint spills over the sides of the housing
do not harden, making the pan stick to the base.
Frequent cleaning with solvents (such as paint thinner)
will warp the dust cover which may then push against the
pan, causing the readout to drift.
