Ultrasonic Oxygen Indicator
INTRODUCTION
Thank you for purchasing a PRO2 check ® Ultrasonic Oxygen Indicator. The
designers of this product have years of experience in the field of oxygen
concentrator repairs. The unreliability and high cost of operation of fuel
cell analyzers led to the invention of the PRO2 check ® Ultrasonic Oxygen
Indicator.
Byrelying on a method already used in many oxygen concentrators to
trigger "Low O2" alarms – ultrasound – Salter Labs has produced a more
cost effective product to check the output of oxygen concentrators. The
PRO2 check ® Ultrasonic Oxygen Indicator responds faster, has no fuel
cell
to replace and is simpler to use than a fuel cell analyzer.
Directions for Use:
There are two (2) controls for the PRO2 check® unit:
1. Pressing and releasing the “on/off” button will turn the unit on or off.
2.
The “pure O2 calibrate” button when pressed and held down
while connected to a compressed gas or liquid U.S.P. oxygen
(> 99.0%) source verifies that the unit is properly calibrated, thus
eliminating the need to have an outside source calibrate the unit.
Since the PRO2check® device uses ultrasound technology to check the con-
centrator operation, there has to be two modes of operation:
1. When the unit is turned on, the software enables the unit to
measure the output of an oxygen concentrator adjusting for the
argon that passes through the sieve beds.
2.
When using the unit with the “pure O2 calibrate” button
depressed the software measures oxygen not adjusting for the
argon. When the “O2 calibrate” button is released, the unit
automatically returns to the concentrator mode and will then again
adjust for the argon and read incorrectly for pure oxygen.
We are sure that the PRO2 check® Ultrasonic Oxygen Indicator will
provide years of fast, reliable operation.

FREQUENTLY ASKED QUESTIONS (continued)
When I am in the Concentrator Mode and hook the unit up to a U.S.P.
oxygen(> 99.0%) source the LCD does not read 99% (± 2), why?
When the unit is in its default (concentrator) mode the device's software
enables the unit to measure the output of an oxygen concentrator by
compensating for the argon that passes through the sieve beds. In this
mode, it will display a false reading (usually ± 90%) if connected to an
oxygen source other than a concentrator. Pressing and holding the “pure
O2/calibrate” button removes the argon compensation and allows the
device to measure the oxygen purity with ±2% of compressed gaseous or
liquid oxygen.
When I am in the Concentrator Mode and hook the unit up to a U.S.P.
oxygen (> 99.0%) source the LCD the display reads - "Concentrator O2
91.8" (approx). What's wrong?
Nothing. When in the Concentrator Mode, the electronic components of
the indicator automatically compensates for the argon found in the gas
produced by an oxygen concentrator. As a result the display will read
approximately90% unless this function is over-ridden bypushing the
“pure O2/calibrate” button.
Whenever I check concentrators with the PRO2 check®, I consistently get
an O2 concentration reading of 96.0 on every concentrator. Why?
Concentrators work at their maximum efficiency (96.0%) at lower flow
rates. When the flow rate is increased the output of the concentrator
typically will decrease slightly. If you question whether the device is
functioning properly, stabilize it to room air and then retest with the
concentrator set on the maximum flow rate or beyond. Be sure to allow
the concentrator to stabilize at the higher flow rate before testing. This
may take as long as 10 minutes.
Will the unit lose calibration when I change batteries?
No. The unit holds calibration even when the battery is removed.

FREQUENTLY ASKED QUESTIONS
Thank you for purchasing the PRO2 check® Ultrasonic Oxygen Indicator.
It
will give you years of trouble-free operation. The following are some of
the frequently asked questions about the operation of this device.
Do I have to calibrate my PRO2 check® unit daily?
No. The PRO2 check® indicator was calibrated at the factory.
How do I know that my PRO2 check® device is accurately
measuringconcentrations?
To verify, simply connect the unit to a source of either compressed gas or
liquid U.S.P. oxygen (> 99.0%) at 2 LPM. Then turn on the device and
hold down the “pure O2/calibrate” button. As long as the display
reads between 99% and 101%, the unit is properly calibrated.
How often should I calibrate my PRO2 check® unit?
As long as you can verify (via the Pure Oxygen Verification Procedure)
that the unit is holding calibration against a U.S.P. oxygen (> 99.0%)
source, the unit does not require calibration.
My accreditation organization as well as our internal policies require
periodic calibration of this type of equipment. Can I calibrate the PRO2
check® device to comply with these requirements?
Yes, if accreditation organizations or internal policies and procedures
require routine calibration, instructions on calibrating the device are
found on pages 6 - 7 of this manual.
Does the unit have to be turned off before verifying or calibrating?
Yes. The unit must be turned off and evacuated to room air before you
begin the oxygen verification or calibration procedures.
Why doesn't the unit drop immediately to room air?
Oxygen is heavier than room air, so it will linger inside the unit. When
there is a flow (either from room air or another concentrator), the reading
will change immediately.
Can I exhale (blow) into the unit to reach room air?
No. You may apply a small suction or flow of room air, but do not exhale
into the unit.

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.

INSTRUCTIONS FOR SPOT CHECKING
LIQUID OXYGEN VESSELS or OXYGEN CYLINDERS
Although the PRO2 check® Ultrasonic Oxygen Indicator is designed, as its
name implies, to check the various functions of an oxygen concentrator, it
can also be used to perform spot checks (± 2%) of gaseous or liquid
oxygen.
To utilize the PRO2 check® device for this purpose follow this procedure:
1. Connect the inlet port on the PRO2 check® unit to a gaseous or
liquid
oxygen source (cylinder or liquid oxygen) via a supply tube.
2.
Turn the oxygen flow on to 2 LPM.
3. Press the “on/off” button to turn the PRO2 check® unit on.
4.
When unit stabilizes the unit display will read "Concentrator O2
91.8" (approx concentration.)
5.
Press and continue to hold down the “pure O /calibrate” button.
6.
Unit will display "Pure O2" and a numeric reading.
7.
If the source gas is oxygen, the display should read between 99%
and 101%.
8.
If the unit display reads "err", "---", "-U-" or any other reading
other than 99.9 (± 2%), the source gas may not be pure oxygen and
should be quarantined for retesting using a more sophisticated method
such as a Servomex* oxygen analyzer.
NOTE: PRO2 check® Ultrasonic Oxygen Indicator can be used to spot
check
the identity and purity of gaseous or liquid oxygen only, it cannot be
used to
performor verify U.S.P. oxygen (> 99.0%) testing since it cannot
provide the required U.S.P. oxygen (> 99.0%) accuracy of ± 0.1%.

ENVIRONMENTAL EFFECTS
Temperature
Under normal operating conditions 32º F to 105º F (0º C to 41º C), the
PRO2 check ®unit's microprocessor and temperature circuit will
compensate
for variations in temperature. The temperature during storage
and shipping
should not reach below -29º F (-34º C) or above 160º F (71º
C). If the unit
has been stored at other than normal room temperatures,
allow unit to
stabilize at room temperature for 15 to 30 minutes. Unit will stabilize quicker
if turned on.
BarometricPressure
The PRO 2 check® multifunctional unit's microprocessor makes it
unnecessary
to recalibrate during minor altitude changes. Please verify
calibration if used
over 5,000 feet.
Note: If readings do not seem accurate, recalibrate the unit.
Vibration
It is recommended that the unit be used in a stable position to prevent the
displayreading from fluctuating.
Note: Unit will not withstand excessive shock or vibration.
Relative Humidity/Water Vapor
The relative humidity (RH) of the gas being sampled will affect the reading
being displayed. As the RH increases, the sample gas becomes diluted with
water vapor. This decreases the percentage of all gases measured including
oxygen. Gases from high-pressure cylinders and oxygen concentrators are
basically dry (< 0.5% RH). Gas measured after a humidifier or that has a
high RH can cause a reading up to 10% lower than the actual reading.
Note: For accurate results, never measure oxygen percentage downstream
from a humidifier. This can damage the unit.
