BACKPRESSURE OR RESTRICTION TO FLOW.
ERRORS IN READINGS WILL RESULT IF THIS IS
NOT FOLLOWED.
THE OXYGEN SENSOR IS A NON-STERILE DEVICE
AND SHOULD BE USED IN CONJUCTION WITH AN
ANTIBACTERIAL FILTER. ALWAYS INSTALL THE
SENSOR ON THE INSPIRED LINE AHEAD OF
FILTERS, HUMIDIFIERS AND MEDICATING DEVICES.
NEVER INSTALL THE SENSOR IN A LOCATION
THAT WILL EXPOSE THE SENSOR TO PATIENTS
EXHALED BREATH OR SECRETIONS UNLESS YOU
INTEND TO DISPOSE OF THE SENSOR AND FLOW
ADAPTER AFTER USE.
When analyzing for oxygen in confined volumes such as
incubators, hoods, etc., the flow diverter must be removed from the
R17MED sensor so that it does not interfere with the rapid exchange of
gases to and from the sensing surface of the sensor.
CAUTION: FAILURE TO REMOVE THE DIVERTER IN THESE
APPLICATION AREAS WILL RESULT IN A MARKED
LOWERING OF THE RESPONSE TIME OF THE
SENSOR.
The R17MED sensor can be placed or hung inside incubators, tents,
etc. When it is necessary to thread the cable through a small hole in
order to gain access to the inside of a chamber, the cable should be
disconnected at the sensor, threaded through the hole, and reconnected
inside the chamber.
The LOCK/UNLOCK key can be used to lock out any accidental
interference to the front panel keys. The LOCK/UNLOCK key acts as a
toggle, pressing LOCK/UNLOCK once renders inactive all keys except
the ALARM SILENCE () key. Pressing LOCK/UNLOCK a second
time unlocks the keypad.
