K-Factor
This field appears if a pulse meter type input is selected and a pulse meter is
connected to CM8281-12 (20 kHz max). Set the unit value a single pulse represents.
Max* This field appears if a scale type input is selected and a scale with 4 - 20 mA output
is connected to CM8281-14(+) and CM8281-16(-). Set the weight associated with
the maximum signal input in this field.
Min* This field appears if a scale type input is selected and a scale with 4 - 20 mA output
is connected to CM8281-14(+) and CM8281-16(-). Set the weight associated with
the minimum signal input in this field.
