7.7 Weighing with tolerance range
You can set an upper or lower limit when weighing with tolerance range and thus
ensure that the weighed load remains exactly within the set limits.

Audio signal:
The acoustic signal depends on the settings in menu block „BEEP“.
Options:
• no
Acoustic signal turned off
• ok
An acoustic signal sounds when load is within tolerance
limits
• ng
An acoustic signal sounds when load is beyond tolerance
limits
