*15mswhenthechatteringlterisinuse(On)
• Measurementaccuracy:Count±1pulse
 Forintegrationcomputation*,thefollowing
accuracies are added.
 Computationstart:+1scaninterval
 Computationstop:−1scaninterval
*Integrationrequiresthemathfunction(/MToption).
• Chatteringlter:Removeschatteringupto5ms
(can be turned on/off on each channel)
*Whenthechatteringlterisoff,connectGX/GP/GMso
that it is not affected by the noise.
• Input threshold level:
Contact (open collector, voltage-free contact):
 Countedwhenachangefrom100kΩor
higherto200Ωorlowerisdetected
