CYLINDER GP-LIFT 1U1839 - Caterpillar

Reweigh Function
The reweigh function allows the operator to subtract the previous bucket weight from the total truck weight. The reweigh function is used when the operator must add or remove material to or from the last bucket to achieve the correct truck weight. The reweigh function can also be used to recalculate bucket weight after PCS has informed the Operator of a weigh error during the lift. The reweigh function allows the following:
Erasing the previous bucket.
Reweighing the previous bucket after adding material to the bucket or after removing material from the bucket.
Reweighing the previous bucket in the event PCS detected a problem with weighing the previous bucket.Reweigh Messages
