6. Troubleshooting
6.1 Overview
PG9000 is a sophisticated pressure 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
PG9000 operation. This troubleshooting guide is intended as an aid in identifying the cause of
unexpected behavior and determining whether the behavior is due to normal operation or an internal or
external problem.
Identify the symptom that 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.

generation/control component. 3.12.5.4,
3.12.5.5
Displays <******> or <OVERFLOW>
where a numerical value should be. Number to be displayed is too large for
allocated space. Usually due to an
erroneous setting or measurement
causing an out of limit high value to be
calculated. Check settings that may be causing an out of
limit high measurement and adjust if
necessary. 3.10.3
