Technical Manual
4 Calibration
4.1 Calibration of poultry scale
This section is relevant only to DOL 53X with software version 6.6 or higher.
The scale should be calibrated at least once a year.
When calibrating equipment, it must have a fixed, stable temperature. Therefore, if you move the equipment into
the livestock house, it requires some time to become acclimatized.
If you connect the scale to a house controller with software version 6.6 or later, it should only be calibrated on
the controller - not on the scale itself.

Calibration deviation
Deviation from previous calibration in percentages.
Voltage
Displays the current input voltage from the scale.
Before calibration, it is important to ensure that the animals do not have access to the scale that needs calibra-
tion. For example, place a bucket over the scale.

to start the calibration.
Follow the status of the calibration through the following steps:
Wait for stable empty scale
Place calibration weight:
Place the calibration weight on the
scale and wait 30 sec.
Remove the calibration weight:
Remove the calibration weight
and wait 30 seconds while the scale is empty. This is to ensure
that the scale remains empty until the calibration is completed.
