13.1. Good Weighing Practice
In order to assure a long-term device operation, wherein correct measurements
are provided, the following principles must be adhered to:
Load the weighing pan steadily
avoiding mechanical shocks.
Place the loads centrally on the
weighing pan (eccentricity errors are
specified by PN-EN 45501
standard, point 3.6.2).
Do not apply concentrated force
(total load in one point).
Avoid side loading, in particular side
shocks.
13.2. Zeroing
To zero mass indication press
key. Zero indication and the following
pictograms are displayed:
and .
Zeroing operation means determining new zero point, recognized by the
weighing device as precise zero. The instrument can be zeroed only when the
indication is stable.
Indication can be zeroed only within ±2% range of the
maximum capacity. If the zeroed value is greater than ±2%
of the maximum capacity, then the software displays
a respective error message: “Zeroing out of range. Press
tarring button or restart the balance”.
