Channel offsets are compensated by the
stored in the Flash Memory. There is no need to use the
command for channels which are recalibrated frequently.
The HP E1313/E1413's Flash Memory has a finite lifetime of approximately ten
thousand write cycles (unlimited read cycles). While executing
once every day would not exceed the lifetime of the Flash Memory for approximately
27 years, an application that stored constants many times each day would unnecessarily
shorten the Flash Memory's lifetime.
