3. While the Nonin logo displays, press and hold the Audible Alarm Pause/Resume
button. After approximately 15 seconds, the message HOLD ALARM PAUSE BUTTON
AND PRESS POWER TO CALIBRATE displays on the monitor. Do not release the
Audible Alarm Pause/Resume button.
4. While continuing to press the Audible Alarm Pause/Resume button, press the ON/
OFF
button.
5. RespSense starts the calibration procedure and displays the following message:
CALIBRATING...
6. Release both buttons.
7. Calibration takes 15 minutes to complete. When calibration is finished, RespSense
returns to normal operating mode.
8. Disconnect the calibration apparatus.
9. Verify calibration:
a. Connect the gas valve, which is already equipped with a T-connector, to a gas bottle
containing 5 Vol% of CO
2
(verifying gas) and RespSense.
NOTE
: Older versions of the
gas valve do not have a pre-attached T-connector. For this configuration, connect a T-
connector and gas sampling tube before connecting the gas valve to the gas bottle and
RespSense. The T-connector allows excess flow to exit into the room.
b. Verify that the gas valve needle is in the green zone of the dial indicator. If the gas valve
needle is in the red zone, the CO
2
tank is empty and should be replaced.
c. Release gas for 4 – 5 seconds (until the ball rises to the top of the column) and then turn
off the gas valve. This equals one exhale. The ball should return to the bottom of the
column when the gas valve is turned off. Repeat 2 – 3 times.
d. Verify the reading of EtCO
2
on the touch panel display. A reading of 33 – 43 mmHg
(4.4 – 5.7 kPa) is considered normal. This should agree with the device accuracy claims
found in the “Capnography Specifications” section.
NOTE:
If the reading is out of range, an internal air leak is possible. Replace the moisture
trap and repeat the calibration procedure. If the out of range reading continues, contact Nonin
Technical Service.
Recommended Inspections and Functional Check
1. Before each use, verify the equipment is clean and in optimal operating condition. See
“Cleaning the Monitor” section.
2. Verify battery capacity by turning on the monitor.
3. Verify the single-use disposable sample line or cannula is free of bends and kinks for
optimal performance.
4. Verify the moisture trap and filter are in position.
5. Visually examine the accessories for defects prior to use.
6. Turn on the monitor by pressing the ON/OFF button until you hear a beep.
CAUTION:
Always turn off the monitor prior to cleaning the monitor or changing the
moisture trap and/or filter.
