initially installed or if the weighing machine is moved to a
substantial distance from the original location. 30 minutes of
warming up of the scale is always needed before initial
calibration.
A reminder when operating our larger capacity
scales:
The scales of the LDS series are calibrated at the factory.
Usually no recalibration is necessary unless major
inaccuracies are observed. If calibration is deemed
necessary, an appropriate test weight of at least 2/3 of the
full capacity of the scale should be used to obtain
accurate weighing.
