STD PRE and EZ PRE Operation Modes
Version 8.7 of the batcher software allows the user to choose between STD PRE (Standard Preset)
and EZ PRE (Easy Preset) operation modes. STD PRE operation is well suited for batch amounts
that do not change, since the program mode must be entered to change the preset and the batch
count must be cleared before starting a new batch. EZ PRE has been designed for users who
frequently change the batch amount. During EZ PRE operation, the preset can be viewed and
changed without entering the program mode and another batch can be started without resetting the
unit.
Note:
Before a batch is started and after a batch is complete, the unit will continue to totalize all
inputs.
Note:
EZ PRE is not available on units with 16 Point Linearization.
