INTRODUCTION
Thank you for purchasing a PRO
using this single, easy to operate device a home care provider can quickly and accurately
perform all of the most common field tests required to service oxygen concentrators:
• Measurement of the concentration of oxygen delivered from the concentrator
• Verification of accuracy of the concentrator's built-in flow control with in the tolerance
of the measuring device and altitude adjustment if needed.
• En s u r i n g t h a t t h e u n i t i s o p e r a t i n g w i t h i n m a n u f a c t u r e r ' s o u t p u t p r e s s u r e
specifications
When used to measure the concentration of oxygen being produced, the device utilizes
technology already used in many oxygen concentrators to trigger "Low O
trasound. By combining this proven sensor technology with built-in pressure and flow
measurement instruments, Salter Labs® has produced in a single unit a simple, convenient, and more cost effective product to check the major output parameters of oxygen concentrators. The indicator when operating in the oxygen concentration measurement mode
responds faster, has no fuel cell to replace, and is simpler to use than a fuel cell analyzer.
The flow and pressure measuring functions of the unit allow the provider to quickly and
easily measure these outputs without changing equipment.
1. Remove the PRO
package. Make sure you have the following items:
• PRO
• 9-volt battery (factory installed) – Spare Battery also included.
• 2 foot connecting tubing
• Carrying case and strap
• Operation Manual
2. The PRO
calibration of the unit's oxygen concentration measurement mode can be
quickly and easily verified by following the "Pure Oxygen Verification"
procedure on page 7 of this manual.
3. If accreditation organizations or internal policies and procedures require rou-
tine calibration, instructions on performing both a "Quick One Step Calibra-
tion Procedure" to USP oxygen can be found on page 7 of this manual. A

____________________________________________
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.
When I am in the Concentrator Mode and hook the unit up to a USP 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 91.8%) if connected to an oxygen source other than a concentrator. Pressing and holding the "pure O
/calibrate" button removes the argon
2
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 USP oxygen
source the LCD the display reads - "Concentrator O
90.1" (approx). What's
2
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 approx imately 90% unless
this function is over-ridden by pushing the "pure O
/calibrate" button.

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 re-test 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.

1. Make sure the concentrator has been running long enough (follow concen trator manufacturer's guidelines) to reach full operational output.
2. Make sure flow rate is above 2 LPM - preferably at the concentrator's high-
est output.
3. Remove any humidifier from concentrator.

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 display reading 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 also damage the unit!

3. The unit will display "PRO2" then "O2" followed by "---"
4. When "---" is displayed release the “pressure” button
5. The display will read either "HPA"* or "PSI"
6. Pressing the “pressure” button at this time will toggle the display between
"HPA" and "PSI"
7. When the preferred view is displayed, wait 10 seconds until unit returns to
concentrator mode and your default setting will be saved
8. To change the default setting, repeat the above procedure
Battery Replacement
When the LCD displays "LO BATT" in the lower left corner, the battery is
low and should be replaced.
NOTE: The
PRO
place battery. A spare battery is included with each unit.
Install a new 9-volt battery by sliding the battery door (located on the rear of the
unit) away from the case. Connect the 9-volt battery to the standard 9-volt battery connection and lay the battery sideways in the battery compartment. Insert
battery door by sliding door back onto unit in the reverse direction of opening.

VERIFICATION & CALIBRATION INSTRUCTIONS
(Concentrator Mode)
PURE OXYGEN VERIFICATION PROCEDURE
To quickly verify that the indicator unit is accurately measuring the concentration of oxygen being produced by a concentrator, perform the following steps:
PRO
1. Connect the “% oxygen/flow” inlet port on the
unit to a USP oxygen(>
99.0%) source (cylinder or liquid oxygen ) via a
supply tube.
2. Turn the O
delivery flow to 2 LPM.
2
3. Press the “on/off” button to turn unit on.
4. When unit stabilizes the display will read - "Concentrator O
(approx. concentration).
NOTE: When in the Concentrator Mode, the electronic components of the
check Elite
®
indicator automatically compensate for the argon
found in the gas produced by an oxygen concentrator. As a result the display
will read 91.8% (± 2%) unless this function is over-ridden by pushing the "pure

7. If the unit is properly calibrated, the display should read between
99% and 101%. The unit is ready to use.
8. If the unit display reads "err, "---", "-U-" or any other reading
other than 99.9 (± 2%), the unit should be recalibrated (See below).
QUICK “ONE STEP” PURE OXYGEN CALIBRATION
The following procedure can be used to quickly and easily calibrate the Multifunction Concentrator Indicator to pure oxygen:
1. Follow ste ps 1 thr ou gh 6 of "P ur e Oxyg en Veri fi cat i o n Pr oced u re"
above.
2. When the unit di spl a y s "Pure O

FULL "TWO STEP" CALIBRATION PROCEDURE
The following procedure may be used to calibrate the PRO
to both room air and USP oxygen (>
99.0%):
1. Do not connect unit to oxygen source or introduce oxygen to the unit at this time
2. Turn unit on by pushing “on/off” button
3. Wait for the unit to stabilize at room air - and the LCD displays “Concentra-
