Weight Increment DO
Output Mode, Weight Decrement DO Output Mode and Weight Section DO
Output Mode.
EMC design with high anti-jamming capability, suitable for
industrial environment.
32-bit ARM CPU with 48MHz clock & higher arithmetic speed.
5 Red LED digital tubes for English character and digit display.
Menu&Shortcut mode operation.
24-bit High-precision and high-speed ∑-△A/D conversion module
with 1/1,000,000 internal
resolution and max. sampling frequency 1280Hz.
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.
Optional weighing input signal mV, V and mA for connecting
‘【mV】Output Type Loadcell’,
‘【V】Voltage Output Type Weighing Transmitter’ and ‘【mA】Current
Output Type Weighing
Transmitter’.
