Front Water will add the admixture with the front water,
Tail Water will add the admixture with the tail water,
Discharge will add the admixture when the materials are added to the truck
or mixer.
Cement Discharge will start the admixture discharge when the cement
discharge begins.
Aggregate Discharge will start the admixture discharge when the aggregate
discharge begins.
Skiphoist Discharge will start the admixture discharge when the aggregate
skiphoist discharge begins.
Last will add the admixture after all other materials (except tailwater) have
been added.
Weighup will start the admixture discharge while the other materials are being
weighed.
Select a material to start adding the admixture when the weighup of that
material begins
Dosage by 100 weight
No
Yes
Dosage by yard of concrete or by 100 weight of cement.
Water weight 0.0 For water based admixtures, water weight per admix volume unit.
Preact Preact is used to account for material still in suspension after the filling is stopped. The amount in suspension
will depend on the distance from the source to the top of the material already on the scale and that, in turn, is
inversely proportional to the amount of weight on the scale – the more weight the less distance.
The preact levels are used to adjust the amount of preact depending on how much material will be in the
weigh hopper when the dispensing for the material is complete - the more material on the scale, the less
material that will remain in suspension

Learn Preact Off
On On to have preacts adjusted by actual differences.
Adjustment Precent 50 Percent by which preact adjustment is made for preact in Learn mode
Deadband 2 Difference band inside which preact learn adjustments will not be made
Minimum Preact Value 5 Minimum possible preact value (this may be a negative number to account for
dynamic load)
Maximum Preact Value 5000 Maximum preact value
Minimum Flow Rate -50 Preact Learn will not be done if the flow rate during material dispensing is less
than this value
Maximum Flow Rate 2000 Preact Learn will not be done if the flow rate during material dispensing is
greater than this value
Preact Weight Band 30 Weight amount between following preact levels
Level 1 Preact 10,000 Preact amount for lowest hopper level (For loss in weight scales, this is the
value always used).
Level 2 Preact 9,000
Preact amount for 2
nd
lowest hopper level
Level 3 Preact 8,000 Preact amount for 3rd lowest hopper level
Level 4 Preact 7,000 Preact amount for 4th lowest hopper level
Level 5 Preact 6,000 Preact amount for 5th lowest hopper level
Level 6 Preact 5,000 Preact amount for 6th lowest hopper level
Level 7 Preact 4,000 Preact amount for 7th lowest hopper level
Level 8 Preact 3,000 Preact amount for 8th lowest hopper level
Level 9 Preact 2,000 Preact amount for 9th lowest hopper level
Level 10 Preact 1,000 Preact amount for 10th lowest hopper level
