Task
If calibrating using pre-wet in calculation mode enter a pre-
wet target value.
Enter a moisture target, for the main water addition and then
press OK.
The moisture target value is only used to set the display
value that the operator sees on the Overview Screen. It can
be any value chosen by the user, and does not have to be
an accurate value. However, if a real moisture value is
required then one of the following values can be entered:
The theoretical value from the mix design
•
The moisture calculated from the raw materials
•
The result of a bake out of the calibrated batch
•
If the result of a bake out is used then it should
•
be noted that this should be done as quickly as
possible as it will be affected by the hydration
process. The concrete should be spread thinly
before performing the bake out.
If the mix consistency would have been improved by adding
or subtracting a certain quantity of water, then this value can
be added at this point, and the OK button pressed.
If no dry weight has been entered into the recipe, then the
calibration process will prompt the operator to enter one at
this point.
Select which sensor measurement mode to use (only
available with compatible sensors)
The Hydro-Control will then display a summary of the
parameters that the calibration will be based on. Check the
details and press OK.
Press the Menu button and then the Overview button to
return to the Overview Screen.
After calibration it is always good practice to monitor the following batches of the same recipe
and to check the strength and quality of the mix output.
