Put a load you want to weigh on the weighing pan. When the
pictogram appears it means that the result is stable and ready to read.
In order to assure long-term operation and appropriate measurements of
weighted loads following precautions should be taken into consideration:
• Loads should be placed on the pan delicately and carefully
in order to avoid mechanical shocks:
• Loads should be placed centrally on the pan (errors caused by
eccentric weighing are outlined by standard PN-EN 45501
ch. 3.5 and 3.6.2):
• Do not load the pan with concentrated force:
• Avoid side loads, particularly side shocks should be avoided

Notice:
Zeroing is possible only within the ±2% interval of the maximal range.
If zeroing is performed beyond this range the <Err2> message and
short audible signal will be emitted.
12.4. Weighings in two ranges
Switching between the I range and the II range happens automatically
(exceeding Max of the I range). Weighings in the second range is
signalled by a pictogram in the top left corner of the display.
Then weighings is done with the accuracy of the II range to the moment
of returning to zero (autozero range
) where the scale switches back
