RPM4 is a sophisticated pressure setting and measuring instrument with advanced on-board features and functions. Before assuming that unexpected behavior is caused by a system defect or breakdown, the operator should use this manual and other training facilities to become thoroughly familiar with RPM4 operation. This troubleshooting guide is intended as an aid in identifying the reason for RPM4 behavior and determining whether the behavior is due to normal operation or an internal or external problem.

Identify the symptom or unexpected behavior you are observing from the SYMPTOM list below. A PROBABLE CAUSE is provided and a SOLUTION is proposed including references to manual sections that provide information that may be of assistance.
