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.

Set Up Procedure / Maintenance

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.

1. Open the rear side of the housing according
to the chapter "Opening the OxySpy", (page 7).
Consider the safety considerations on
page 5.
2. Pull the battery (if there is any) out of the bat-
tery holder, by hooking a finger under the bat-
tery.
Take care of the environment: Dispose of the
used battery properly!
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
sensor" on
page 11 or page 8, respectively.
