The Actual Mix Ratio register contains the
instantaneous calculated mix ratio.
• The value reported is the ratio antecedent
multiplied by 100. The ratio consequent is
always 1.
Example
: Value = 250 >> A mix ratio of 2.5:1
(Material A to Material B)
• If the current recipe ratio is 0:1 (1K recipe) this
value will be 0.
This register is valid only during a mix operation.
