•
Regular RPT recalibration (see Section 5.2).

PPCK+ is a sophisticated pressure setting and measuring instrument with advanced on-board
features and functions. Before assuming that unexpected behavior is caused by system defect or
breakdown, use this manual and other training facilities to become thoroughly familiar with
PPCK+ operation. For rapid assistance in specific situations (see Section 6).
PPCK+ is covered by a limited one year warranty. Unauthorized service or repair during the warranty
period is undertaken at the owner's risk and may cause damage that is not covered under warranty
and/or may void the warranty.
