Quick Tips and further information.
• If you can get the original L/W data out of the system that will mean you don’t have to lug test
weights to the job.
• Reading the Parameters as listed before replacement: - As you won’t know what the parameter
is in each config it is best just to write them all down and then re-enter the changed values with
the new SCPU.
