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 dis­played. 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

O

2

percentage does
not change during the calibration.
If the OxySpy is not used, it switches off auto­matically.
Thanks to its ergonomical design and its single
button operation, it can be operated by one
hand.
The OxySpy displays the sensor or battery sym­bol, if the

O2sensor or the battery are used up.

Both are easily changed by the user.

English

Warnings and Safety Considerations

5

• If you are unsure about the displayed

O

2

per­centage: Repeat the measurement or check
the value with another system. For measure­ments 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 consi­der the general safety considerations of using
pure oxygen or oxygen enriched gases!

• If the

O2sensor 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 cal­culate 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

O2limit) 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

O

2

sensor contain corrosi-

ve liquid. If the battery or

O

2

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.

Set Up Procedure / Maintenance

After a short push on the button, the OxySpy will
display the measured

O

2

percentage. If need be,
the unit indicates that it requires calibration or
indicates that no

O2sensor 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 electro­nics and the mounting ring.

• Open the OxySpy only if the battery or the

O

2

sensor must be replaced.

• Do not touch the electronics.

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 disconnec­ted, 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

O

2

sensor.

• After opening the sealed package the

O

2

sen­sor needs 30 minutes start-up time. This
means that calibration cannot be made until 30
minutes after opening the package. See "Cali­bration" page 11.

• Take care of the environment; properly dispose
of used

O2sensor (if there is any

O ring).

Attach the mounting ring by twisting it onto the
O2sensor, exactly as shown in the picture on the
left. Maneuver until it fits snugly.

Write the date of the fitting onto the

O

2

sensor.

5. Insert the plug into the socket of the

O

2

sen­sor. 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

O

2

percentage may be incorrect.

If "no" and the

O2sensor 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

O

Choose the correct depth unit (mtr. or ft.) to dis­play 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

O

2

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

O

English

Calibration

11

The calibration can be made either in air
(20.9%

O2) or pure oxygen (100%

O2). The Oxy­Spy will automatically detect which gas is being
used for calibration.
The

O2sensor measures the partial pressure of

the oxygen and the OxySpy calculates the

O

2

percentage (

O

2

%) from it. Changes of the
ambient pressure or temperature will influence
the

O2measurement values. This is the reason
why the OxySpy has to be calibrated frequently.
Once the

O2sensor has been calibrated, the
maximum allowed partial pressure of oxygen
(pp

O2limit)

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

O

2

percentage in the air is

below 20.7%

O

2

.

• The measured

O2percentage in the air

exceeds 21.1%

O2.

• The CAL symbol is displayed.

• If you are unsure about the displayed

O

2

per-

centage.

The

O

2

percentage of the gas mixture (used for
the calibration) must not change during the cali­bration.

The duration of an OxySpy calibration is a maxi­mum 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

O2sensor. Without this flushing, the calibra­tion may not be successfully completed. Do not
blow through the OxySpy as the C

O

2

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

O2sensor has been calibrated, the

OxySpy will display the pp

O2limit (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

O

2

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

O

2

limit is higher than 1.6 bar,

the pp

O2symbol will flash to warn the diver.

• The maximum partial pressure of oxygen

(pp

O

2

limit) for calculating 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.

• For strenuous dives or diving in cold water the
chosen pp

O

2

limit should not exceed 1.4 bar.

The OxySpy switches automatically into the nor­mal measurement mode.

Calibrating
with pure
oxygen

The OxySpy can also be calibrated with pure
medical oxygen (100%

O2).

• Please consider the general safety con­siderations 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 "Measure­ment" (page 14).

After the pure oxygen calibration: "Flush"(move
it back and forth slowly) the OxySpy for 1 minu­te 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 com­pleted 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

O

2

% values are still
based on the old calibration data. The CAL sym­bol is displayed to inform you about the unsuc­cessful calibration.

Repeat the calibration if the CAL symbol is still
displayed after the calibration. Several calibrati­ons without success could be an indication that
the

O

2

sensor needs to be replaced or a fluctua­tion of the mixture of the calibration gas during
the calibration. The fluctuation of the gas mixtu­re 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 elas­tic rings without resistance.

• Check the OxySpy in air before each measu­rement 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

O2values and the chosen pp

O2limit.
The indicated maximum operation depth will be
rounded to 0.1 mtr. or 1 ft.

If the selected pp

O2limit is higher than 1.6 bar,

the pp

O2symbol 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

O

2

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

O2sensor",

page 8).

Disconnecting the

O

2

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

O2sensor
requires 30 minutes to stabilize in air. Calibration
should be made only after this "warm-up" time.

The battery and the O

2

sensor 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.
