1/1,000,000 internal resolution and sampling frequency 400Hz.
- Special anti-vibration digital filtering algorithm for ensuring the
weighing stability and accuracy when there is strong vibration on
the load receptor, and the rapid response capability when the
weight signal changes.
- Max. Connection Quantity: 8 Loadcells (350Ω).
- Auto Zero Initial Calibration after Power-on, Auto Zero Tracking,
Zero Fine Adjustment, Zero Calibration and Load Calibration
functions available.

output or ‘High/Medium/Low Speed Feed’ control.
- 10 Recipes for packing control.
- Optional ‘Fall Value Auto Correction’ function.
- Optional ‘Auto Pause for Deviation Alarm’ function.
- Optional ‘Target Batch Control’ function [With Target Batch Count
or Target Batch Weight finished, the packing process will stop
automatically].
- 2 Optional communication ports for connecting Host IPC/PLC, LED
Remote Display, Serial Printer and Wireless Module.
- The present Batch Record can be printed automatically and manually.
- 1000 Historical Batch Records, Totalizing Reports and Recipes can
be queried and printed.
- With the multitasking mode, the weighing&control process will
not be interrupted by parameter setting and the other operations.
