Introduction
4
The OxySpy is a portable Oxygen Analyser for
the trained and certified mixed gas diver. The
OxySpy can be held directly against the slightly
opened diving tank and displays within seconds
the oxygen percentage of the gas.
By pressing the push button the display can be
frozen. By pressing the push button once more
the maximum operation depth (MOD) is dis-
played. The calibration of the OxySpy is as easy:
The unit detects itself whether the calibration is
made in air or with pure oxygen. A calibration
can only be terminated if the
O2
percentage does
not change during the calibration.
If the OxySpy is not used, it switches off auto-
matically.
Thanks to its ergonomical design and its single
button operation, it can be operated by one
hand.
The OxySpy displays the sensor or battery sym-
bol, if the
O2 sensor or the battery are used up.
Both are easily changed by the user.

Warnings and Safety Considerations
5
• If you are unsure about the displayed
O2
per-
centage: Repeat the measurement or check
the value with another system. For measure-
ments after filling the tank and before diving
always use two different measuring units.
• Check the OxySpy in air before each series of
measurements. If necessary, calibrate the
OxySpy. See page 5.
• Using pure oxygen or oxygen enriched gas
needs special safety measures! Please consi-
der the general safety considerations of using
pure oxygen or oxygen enriched gases!
• If the
O2 sensor symbol is shown, the display-
ed values can be wrong.
• If the diver uses the wrong value of the gas
mixture he/she or the dive computer could cal-
culate insufficient decompression time (EAD
etc.) or oxygen toxicity (MOD, CNS% etc.).
Both situations could result in death or serious
injury.
• The maximum partial pressure of oxygen
(pp
O2 limit) necessary for the calculation of the
maximum operation depth (MOD) should not
exceed 1.6 bar (the max. value for sports
divers). Higher values may result in death or
serious injury.
• Avoid risky situations which are marked in the
this manual with and .
• Do not use the OxySpy in pressure chambers.
• Do not submerge the OxySpy in water.
• The battery and the
O2
sensor contain corrosi-
ve liquid. If the battery or
O2
sensor leaks: Do
not let the liquid come into contact with skin,
eyes or mouth. If it does, flush the affected
area with water for at least 15 minutes. Consult
a doctor. Do not inhale vapor. Immediately
clean the leakage from the instrument with a
soft towel and dispose of the towel.

The supplied battery and the
O2 sensor have to
be fitted. Similar to the finite life of a battery, the
O2 sensor has a certain lifetime. From the first
time that a
O2
sensor contacts oxygen it starts to
be used up. To keep the lifetime of the
O2
sensor,
its airtight package should only be opened before
the sensor is used the first time.

Set Up Procedure / Maintenance
After a short push on the button, the OxySpy will
display the measured
O2
percentage. If need be,
the unit indicates that it requires calibration or
indicates that no
O2 sensor is connected.
The OxySpy switches off automatically, at the
latest 30 minutes after switching on. The unit
cannot be switched off manually.
• Open the OxySpy only in a clean and dry area
away from water, dust and other contaminants.
It prevents soiling and damage to the electro-
nics and the mounting ring.
• Open the OxySpy only if the battery or the
O2
sensor must be replaced.
• Do not touch the electronics.
1. Pull the rear rubber ring off the housing.
2. Remove the 7 screws with the enclosed scr-
ewdriver and separate the two parts of the hou-
sing.

1. Open the rear side of the housing according
to the chapter "Opening the OxySpy" (page 7).
Consider the safety considerations on page 5
and the ones on the
O2 sensor and its package.
2. Take the
O2 sensor (if there is already one) out
of its position and pull off the mounting ring.
If the
O2 sensor is disconnected while the unit is
on, the display shows the word "no" and the O2
sensor symbol.
In this situation the OxySpy switches off after 5
minutes automatically.
3. Carefully pull the plug out of the socket. The
tab, which stops the plug from being disconnec-
ted, has to be pulled back while pulling out the
plug.
Do not pull on the wires!
• Do not open the airtight container before you
need to use the
O2
sensor.
• After opening the sealed package the
O2
sen-
sor needs 30 minutes start-up time. This
means that calibration cannot be made until 30
minutes after opening the package. See "Cali-
bration" page 11.
• Take care of the environment; properly dispose
of used
O2
sensor! The sensor should be dis-
posed of according to local laws.

Set Up Procedure / Maintenance
4. Take the new O2 sensor out of its package.
Take the O ring off the O2 sensor (if there is any
O ring).
Attach the mounting ring by twisting it onto the
O2 sensor, exactly as shown in the picture on the
left. Maneuver until it fits snugly.
Write the date of the fitting onto the
O2
sensor.
5. Insert the plug into the socket of the
O2
sen-
sor. Make sure that the tab, that secures the
plug, is back in place. The lug of the mounting
ring must fit into the notch of the housing.
6. If a battery is mounted: Switch the unit on and
check that the display is on.
The unit will show the CAL symbol, because the
OxySpy requires calibration. The displayed
O2
percentage may be incorrect.
If "no" and the O2 sensor symbol is displayed
check the chapter "Trouble Shooting", page 16.
7. Carefully refit together the 2 parts of the case.
Make sure that none of the wires get trapped
and damaged by the case. Take care that the
two parts fit together well and carefully tighten
the 7 screws.
8. Locate the rubber ring into the housing so
that its opening does not close the gas flow
to the
O2
sensor.
9. Calibrate the OxySpy or fit a new battery.
See "Calibration" or "Fitting the Battery" on
page 11 or page 10, respectively.

3. Wait a minimum of 2 minutes before installing
the battery. Check that it is the correct type of
battery (see "Technical Information" page 20).
Press the battery into the battery holder until it
snaps in place ( + on the top). The battery hol-
der prevents an incorrect fitting.
4.
Switch the unit on and check if the display is on.
If the unit cannot be switched on, repeat step 2
and 3.
Choose the correct depth unit (mtr. or ft.) to dis-
play the maximum operation depth (MOD) by
quickly pressing the push button.
To confirm the depth unit press the push button
for at least two seconds.
Check the chosen metric system before
refitting the parts of the case!
The unit will show the CAL symbol, because the
OxySpy requires calibration. The displayed
O2
percentage may be incorrect.
5. Carefully refit together the 2 parts of the case.
Make sure that none of the wires get trapped
and damaged by the case. Take care that the
two parts fit together well and carefully tighten
the 7 screws.
6. Calibrate the OxySpy or mount a new sensor.
See "Calibration" or "Fitting the
O2

Calibration
11
The calibration can be made either in air
(20.9%
O2 ) or pure oxygen (100% O2 ). The Oxy-
Spy will automatically detect which gas is being
used for calibration.
The
O2 sensor measures the partial pressure of
the oxygen and the OxySpy calculates the
O2
percentage (
O2
%) from it. Changes of the
ambient pressure or temperature will influence
the O2 measurement values. This is the reason
why the OxySpy has to be calibrated frequently.
Once the
O2 sensor has been calibrated, the
maximum allowed partial pressure of oxygen
(pp O2 limit) can be set. This value is needed by
the OxySpy to calculate the maximum operation
depth (MOD).
A new calibration is required when:
• The measured
O2
percentage in the air is
below 20.7% O2
.
• The measured
O2 percentage in the air
exceeds 21.1% O2 .
• The CAL symbol is displayed.
• If you are unsure about the displayed
O2
per-
centage.
The
O2
percentage of the gas mixture (used for
the calibration) must not change during the cali-
bration.
The duration of an OxySpy calibration is a maxi-
mum of 30 seconds.
The calibration can be interrupted at any time by
pressing the button.
In hot or humid climates, the OxySpy should be
calibrated either in pure oxygen (100%) or in
compressed air from a tank.
What you
have to
know
about
calibration
English

Calibration
12
1. Before the calibration of the OxySpy in air
(20.9%
O2 ) it has to be moved slowly back and
forth, through the air, for about 1 minute to flush
the
O2 sensor. Without this flushing, the calibra-
tion may not be successfully completed. Do not
blow through the OxySpy as the C
O2
in your
breath would cause an incorrect calibration.
2. Press the button until "CAL" and "run" appear.
"CAL" and "run" will flash during the calibration.
Move the OxySpy back and forth, slowly, during
the entire 30 second calibration.
3. After the
O2 sensor has been calibrated, the
OxySpy will display the pp O2 limit (necessary for
calculating the MOD). By quickly pressing the
push button the setting may be changed in the
range of 1.2 to 1.8 bar, displayed in 0.05 bar
increments.
To confirm the indicated pp
O2
setting press the
push button for at least 2 seconds.
If neither changes nor confirmations are made
within 30 seconds, the OxySpy automatically
switches back to the default setting of 1.4 bar.
If the selected pp
O2
limit is higher than 1.6 bar,
the pp O2 symbol will flash to warn the diver.
• The maximum partial pressure of oxygen
(pp
O2
limit) for calculating the maximum opera-
tion depth (MOD) should not exceed 1.6 bar
(the max. value for sports divers). Higher
values may result in death or serious injury.
• For strenuous dives or diving in cold water the
chosen pp
O2
limit should not exceed 1.4 bar.
The OxySpy switches automatically into the nor-
mal measurement mode.

Calibrating
with pure
oxygen
The OxySpy can also be calibrated with pure
medical oxygen (100% O2 ).
• Please consider the general safety con-
siderations of using pure oxygen!
• The calibration gas has to be 100%
medical oxygen.
• At the gas input make sure that there is
a good seal and that air cannot be
sucked in.
The calibration procedure with pure oxygen is
similar to the one described in the chapters
"Calibrating in air" (page 12) and "Measure-
ment" (page 14).
After the pure oxygen calibration: "Flush"(move
it back and forth slowly) the OxySpy for 1 minu-
te in air and check the indicated value. The
value must be between 20.7 and 21.1%
O2 . If
not, redo the calibration.
If the calibration has not been successfully com-
pleted or the calibration has been interrupted by
pressing the button switch, the display will show
a "- - -", for a short time. The OxySpy will then
change automatically into the measurement
mode. No new calibration values have been
entered and the indicated
O2
% values are still
based on the old calibration data. The CAL sym-
bol is displayed to inform you about the unsuc-
cessful calibration.
Repeat the calibration if the CAL symbol is still
displayed after the calibration. Several calibrati-
ons without success could be an indication that
the
O2
sensor needs to be replaced or a fluctua-
tion of the mixture of the calibration gas during
the calibration. The fluctuation of the gas mixtu-
re might have been caused by air leaking in at
the gas input due to a bad seal.

Measurement
14
Consider the following points if you measure
with the OxySpy:
•
The gas must be able to flow through both elas-
tic rings without resistance.
• Check the OxySpy in air before each measu-
rement by "flushing" it (moving it back and forth
for 1 minute in the air). If the displayed value is
not between 20.7 and 21.1%
O2 , the OxySpy
has to be calibrated.
• The OxySpy must have a steady stream of the
gas until the displayed
O2 % value has stabili-
zed.
• At the gas input (the rubber ring) make sure
that there is a good seal and that air can not be
sucked in.
1. Press one of the two rubber rings against the
tank valve.
2. Open the valve until you hear a gentle, uni-
form hiss and wait until the displayed
O2 % value
has stabilized.
3. "Freeze" the display by briefly pressing the
push button. For confirmation the "%
O2 " starts
flashing.
4. Close the tank valve.

5. If the displayed value does not match with
your expectation, repeat the measurement or
calibrate the OxySpy. See "Calibration" page 11.
6. Record the results of your measurement.
7. After quickly pressing the push button, the
OxySpy will calculate the MOD based on the
measured
O2 values and the chosen pp O2 limit.
The indicated maximum operation depth will be
rounded to 0.1 mtr. or 1 ft.
If the selected pp
O2 limit is higher than 1.6 bar,
the pp
O2 symbol will flash to warn the diver.
8. By pressing the push button once more the
OxySpy returns to measuring mode.
Repeat the measurement until you are sure
that
you measured the actual oxygen percentage
of
the gas mixture.

O2Sensors
19
The
O2
sensors have, like batteries, a certain
lifetime. From the first time that a sensor contacts
oxygen it starts to be used up. They can be
replaced by the user (see "Fitting the
O2 sensor",
page 8).
Disconnecting the
O2
Sensor from the socket
does not extend it's life. On page 20 you will find
more information about storing the OxySpy.
After opening the airtight package the
O2 sensor
requires 30 minutes to stabilize in air. Calibration
should be made only after this "warm-up" time.
The battery and the O2sensor contain corrosive
liquid. If the battery or O2sensor leaks: Do not
let the liquid come into contact with skin, eyes
or mouth. If it does, flush the affected area with
water for at least 15 minutes. Consult a doctor.
Do not inhale vapor. Immediately clean the
leakage from the instrument with a soft towel
and dispose of the towel.
