11.5 Calibration
For more information on the keys necessary to access this menu group, go to

Navigation Pilot .
With this menu group the scale is calibrated. In addition to calibration at full
load, part load calibration is also possible. If you want to move the scale to a
different location after calibrating it, you can use the geo value to compensate
for the differing gravitational pull, without having to recalibrate the scale (not for
applications subject to weights and measures legislation). Precalibration with­
out weights is also possible by entering the standardized signal (mV/V).
Example of calibration of a tank weigher:
S
Three 1000kg load cells with sensitivity of 1.99995mV/V, 2.00005mV/V and
2.00000mV/V respectively are used.
S
The maximum load is 1500kg; the interval 0.5kg
S
The weight of the empty tank is 600kg.
