Troubleshooting
If you experience a problem using the OxyFlo Pro that you are unable to
correct by reconnecting the probe(s) and/or turning off and turning back on
the monitor, please contact Oxford Optronix technical support (see p2 of
this document).
WARNING
Do not attempt to open the OxyFlo Pro. There are no user-
serviceable parts inside. There is a risk of electrical shock or
other injury or permanent damage to the monitor.
The following is a list of possible monitor errors / failure modes and
suggestions for correcting them.
The display does not confirm the connection of a probe even though a
probe is connected
Was your monitor manufactured prior to May 2015? If so it may only
function if
pairs
of probes are plugged into the monitor (i.e. into channels 1
& 2 for the OxyFlo Pro and into channels 1 & 2 and/or channels 3 & 4 for
the OxyFlo Pro XL).
If it is intended to operate the monitor with only a single probe, then an LDF
interlock adapter must occupy the corresponding unused channel. The LDF
interlock adapter is available as an optional accessory (product code
IA100NX).
If the monitor does not register the presence of a probe even though the
corresponding second channel is occupied by another probe or an interlock
adapter, then this is indicative of a probe fault. Try a spare probe if available
and/or carry out the simple probe integrity check (section 5.2). If the
problem persists please contact technical support.
The monitor does not seem to power up
Check that the NX-PSU universal AC adapter itself is receiving power from
the wall socket (i.e. that the wall socket is live) by confirming that the
integral LED is lit.
Check that the male connector of the NX-PSU universal AC adapter is
securely seated in the
DC POWER IN
inlet at the rear of the monitor.
Check that the monitor isn’t in a ‘surge prevented mode’ by turning off the
AC adapter, waiting 2-3 minutes, then turning the AC adapter back on.
