3.1.4. Submenu “Calibration”
This menu allows the operator to perform either a practical or a theoretical calibration. During the practical
calibration a desired load has to be applied a zero / full scale span calibration by using of at least two
points. Additional entered points will increase the accuracy.
The theoretical calibration allows to enter the known input voltage ratios but it will not reach the accuracy
of a practical calibration due to tolerances of electronic components.
3.1.4.1. Two position practical
calibration “2P”
The two position calibration allows the
zero of the scale and some other value at
almost any position of its characteristics,
assumed that the complete system is
linear.
3.1.4.1.1. Zero calibration “ZC”
This zero calibration is always the first
step to determine the calibration data.
After pressing
the information
come up to remove any load. An
additional pressing
starts the zero average. After counting
from 0…100 it returns to the ZC-menu.
Do only Zero calibration will move weighing
function parallel to previous one.
3.1.4.1.2. Span calibration
with balance
“BW”
After confirmation an input window is
opened to enter the balance weight
according the selected scale division.
Shown balance weight is Fullscale.
After pressing
the operator
will be informed to place the real balance
test weight on scale.
Establish span by pressing
.
After taking 100 samples of that test
weight the calibration has been saved.
Notice: If you reach the editing field by
error and would like to abort:
• enter any value
