MSF BITS – (Motion Stabilization Filter) 

Used for applications with constant or static type loads to keep display value stable. 
MSF1_2 (1 count up – 2 counts down). 

MSF2_4 

MSF4_8 

MSF5_10 

Set one bit only. 

 

ZERO-DEAD-BAND Bits 

Useful for Auto-Tare functions with production runs. 
Set only one bit. 

ZEROBAND_025 = .025% full scale 

ZEROBAND_05   = .05%   full scale
