Initial Setup
Before calibration can be done, the system integrators will need to have completed any setup to allow
the system to be run, and you will need to be able to run the system.
Engineering Units
By default the measuring units of the controller are;
• weight kg
• flowrate kg/h
• total kg
All settings must be entered using these measured units. The units can be changed if required.
Step Quick Keys
p30 Select weight units 2112
Select flowrate units 2114
Select totaliser units 2115
Measuring Range
Set the measuring range to the largest value that will occur during normal operation. Most settings hav-
ing the same units as one of the capacities are stored as a percentage of this capacity. If the capacity is
changed, these settings will also change.
Step Quick Keys
p30 Enter weight capacity 2121
Enter flowrate capacity 2123
Enter the internal & external
totaliser resolutions
2342 & 2343
Display Resolution
The display resolution for each engineering value can be changed if needed.
Step Quick Keys
p30 Enter weight division 2131
Enter flowrate division 2133
