INTRODUCTION
Thank you for purchasing a Respond O2™ 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 Respond O2™ Ultrasonic
Oxygen Indicator.
By relying on a method already used in many oxygen concentrators to
trigger "Low O 2" alarms – ultrasound – Respond O2™ Oxygen
indicator offers more cost effective product to check the output of
oxygen concentrators. The Respond O2™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 Respond O2™unit:
1. Pressing and releasing the “on/off” button will turn the unit on or
off.
2. The “pure O2calibrate” 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 Respond O2™device uses ultrasound technology to check
the concentrator 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 O2calibrate” button
depressed the software measures oxygen not adjusting for the
argon. When the “O2calibrate” 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.

INITIAL SETUP
1. Remove the Respond O2™Ultrasonic Oxygen Indicator from
the package. Make sure you have the following items:
• Respond O2™indicator unit
• 9-volt battery (factory installed) – Spare battery also ncluded
• 2 foot connecting tubing
•Carrying case and strap
• Operation Manual
2. The Respond O2™Ultrasonic Oxygen Indicator was calibrated
at the factory. However, the proper calibration of the unit's
oxygen concentration measurement mode can be quickly and
easily verified by following the "Pure Oxygen Verification"
procedure on page 6 of this manual.
3. If accreditation organizations or internal policies and
procedures require routine calibration, instructions on
performing a "Quick One Step Calibration Procedure" to
U.S.P. oxygen (> 99.0%) can be found on page 6 of this
manual. A “Full Two Step Calibration Procedure" to both
U.S.P. oxygen (> 99.0%) and room air can be found on page
7of this manual.
Low Battery Indicator:
When the unit displays “LO” and “BAT” in the lower left corner,
battery is low and should be replaced. See page 8.

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 O 2/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 approximately 90% unless this function is over-
ridden by pushing the “pure O2/calibrate” button.
Whenever I check concentrators with the Respond O2™, I
consistent get an O2concentration 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
The following are some of the frequently asked questions about the
operation of this device.
Do I have to calibrate my Respond O2™ unit daily?
No. The Respond O2™indicator was calibrated at the factory.
How do I know that my Respond O2™ device is accurately
measuring concentrations?
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 OB2B/calibrate” button. As long as
the display reads between 99% and 101%, the unit is properly
calibrated.
How often should I calibrate my Respond O2™ 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 Respond O2™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 O 220.9) 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 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 Respond O2™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 Oxygen Concentrations:
Follow the steps below to measure the concentration of oxygen being
supplied by an 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 from concentrator.
4. Connect supply tubing to the concentrator oxygen outlet and the inlet
port
5. Turn on the 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
The Respond O2™ Ultrasonic Oxygen Indicator can also be used to
perform spot checks (± 2%) of gaseous or liquid oxygen as follows:
1. Connect the inlet port on the 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 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 O2/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: Respond O2™ Ultrasonic Oxygen Indicator can be used to spot check
the identity and purity of gaseous or liquid oxygen only, it cannot be used to
perform or 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
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.
Barometric Pressure
The Respond O2™ 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
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 damage the unit.
