Backpressure may have
fluctuated due to problems with
the restrictor. The restrictor may
be blocked. Consider replacing the restrictor.
The pressure was outside
specification. The pressure was outside the
upper and lower pressure limits. Repeat the test with changed flow
settings.
The % compression value was
over the limit!
There may be air bubbles in the
pump head.
Purge the pump (

page 54).
The flow may have been too
high. Repeat the test with reduced flow.
The % compression value was
below the limit! The flow may have been too
low. Repeat the test with increased flow.
