Ultrasonic Oxygen Indicator
INSTRUCTIONS FOR CHECKING O2CONCENTRATORS
To turn unit on and off: To turn the unit on or off press and release the
“on/off” button on the lower left-hand side of the unit. (EXAMPLE:
Concentrator O2 20.9) When the unit is turned on the device defaults to the
mode in which the software enables the unit to measure the output of an
oxygen concentrator compensating for the argon that passes through the
sieve beds. The display will read "PRO", then "O2" and finally
"Concentrator O2" and a number. If the PRO2 check® unit is hooked up
to
an operating concentrator, the device will automatically measure the
concentration of the oxygen being produced and show the value on the
LCD display. The unit's default operating mode automatically compensates
for the argon that passes through the sieve beds, it will display a false
reading (approximately 90%) if connected to an oxygen source other than
a concentrator unless the specific actions discussed on pages 6 - 7 of this
manual are taken. If the device is not hooked up to an oxygen source it will
measure and display the concentration of oxygen in the ambient air
(usually 20.9%). Reading may vary if sample gas remains in unit.
To turn the PRO2 check® device off, press and release the “on/off”
button.
The unit will display “OFF” and shut down. To conserve battery
life, it
automatically shuts down if any one of the unit's functions is not
utilized
for approximately 5 minutes.
Measuring OxygenConcentrations:
Follow the steps below to measure the concentration of oxygen being
supplied byan oxygen concentrator:
1.
Make sure the concentrator has been running long enough (follow
concentrator manufacturer's guidelines) to reach full operational output.
2.
Make sure flow rate is above 2 LPM - preferably at the concentrator's
highest output.
3.
Remove any humidifier fromconcentrator.
4.
Connect supply tubing to the concentrator oxygen outlet and the inlet
port on the PRO2 check®.
5. Turn on the PRO2 check® device (See above).
6. The indicator will stabilize in about 10 seconds and provide an
accurate reading on the LCD display.
7. If there is any question to the accuracy of the reading, perform the
"Pure Oxygen Verification Procedure" and if necessary the “Quick
One Step Pure Oxygen Calibration Procedure on page 6.
CAUTION: Do not check concentrator with humidifier in place.
Humidity can affect unit's readings and damage the unit.
NOTES: Never check a concentrator while holding down the "pure O2 /calibrate"button.
You will get a false reading. You must hold down the "pure O2 /calibrate" button to
check unit against a source of U.S.P. oxygen (> 99.0%) cylinder or liquid oxygen.
