The following menus show temperature probe
information. These readings are more difficult to utilize,
as the RTD probes are resistance devices, whose signals
are processed before input to the A/D converter. Of more
interest will be the OFFSET values. If these values are
off by a large amount or show a variance in one RTD, a
potential fault could be indicated.

This menu is used to cancel the flag set by the
detection of residual pressure during blowdown
when the compressor unloads. The unloaded
pressure in the piping should be below 5 psig
during the unload period. If not, a flag will be set,
and the HIGH DISCHARGE PRESSURE indicator
will be blinking at 1 second intervals if the STAGE
2 blowdown fails to reach the 5 psig trip point.
Likewise, the HIGH INTERSTAGE PRESSURE
light will blink when the interstage does not reach
the 5 psig point. If the setting is cleared while the
indicator is lit, the indicator will remain lit.
