Repeatability is expressed as a standard deviation from 10 weighing cycles.
Stabilization time depends on the ambient conditions and the dynamics of weighing pan loading; specified for FAST profile.
* Power consumption depends on the terminal configurations as well as the number and type of external devices connected.
1 Barcode scanners, available as weighing instrument accessory, communicate with the instrument via RS232 interface exclusively.
