General Specifications
Thank you for buying DE-OX®ZIP PRO analyser. It represents the simplest and up-to-date measurement
instrument for the analysis of oxygenate mixed gas for mixed gas diving. It has been especially designed and
manufactured for the analysis of binary and ternary gas mixtures like
Nitrox, Heliox and Trimix.
DE-OX®ZIP PRO comprises in just one integrate device the oxygen
sensor, the electronic board and the battery. The electrochemical sensor
gives a proportional electrical signal with the oxygen percentage in the
mixed gas. On the unit’s display, this signal is transformed in easy-to-
read oxygen percentage information given in real time.
Main features:
oDisplay of oxygen percentage in the range 0.0 -100.0%.
oFull digital measurement instrument

oStandard 9Volt transistor battery.
oSimple battery and sensor replacement.
oDirect connection to every kind of tank valve with TEMC
®rubber cup.
oSoft protection and transport bag.
oDimensions: max 7,5x4,2 cm weight 250 grams.
Powering On and Warming Up
Press the On/Off key for more than one second, until the display shows “On”, After that the “Att” (WAIT) message
will be displayed for about 4 seconds, then the sensor auto-calibration procedure is started. The auto-calibration
lasts about 5 seconds; during this time the display will show the messages “CAL” and “Att” alternatively.
Be sure that during this time the sensor is exposed to the gas mix with Oxygen percentage as programmed in the
O2c parameter (see Programming procedure). By default, for simplicity, the O2c value is set at 21% that
corresponds to the percentage of Oxygen in free air in this case be sure that flows air on the sensor before
switching on and during the warm up time.
Warning
During the warm up time if the oxygen percentage of the mixed gas flow is different from the value of
calibration set in the instrument, a failed calibration is obtained and a consequent wrong analysis value
will be read.
Reading Page
At the end of the warming up and calibration time, the display will show the blinking value in mV read from the
oxygen sensor during calibrations: the instrument is now ready to read oxygen concentration into the gas mix.
Connect the sensors to the mixed gas flow with a flow of 0,5-2,0 litres/minute at ambient pressure (typically 1 bar)
and temperature (typically 20°C). Now on the display the Oxygen content will be continuously displayed. While the
instrument is in oxygen percentage display mode, keeping the <Calib key pressed for more than 1 seconds
causes the device to display the Oxygen sensor output in mV. To read this value is periodically necessary in order
to know if the sensor is correctly working or is exhausted.
Warning
During gas analysis the instrument and the sensors must be firmly kept and must not be shaken. The gas
pipe used to provide gas mix to the sensor must allow free gas flowing.
Warning
The mixed gas flow, must be 0,5-2 litres/min at ambient pressure (typically 1 bar) and temperature
(typically 20°C) or DE-OX®ZIP PRO will yield a wrong gas analysis. All the analysis concentration shown
on the display will be wrong. Wrong Oxygen analysis may lead to death.

DE-OX® ZIP PRO Oxygen analyzer Draft Issue n. 1.2 of 27/02/11 page4
Programming Procedures
Keep the ^ Prog key pressed for more than two seconds, then release the key. On the display will appear “Pr” for
two second in order to advice the start of the programming procedure. It is possible to program:
oAL1 Minimum alarm threshold expressed in % oxygen concentration
oAL2 Maximum alarm threshold expressed in % oxygen concentration
oFSc Value expressed in % oxygen concentration corresponding to the current output full scale value
(20mA). 4mA always correspond to zero % Oxygen concentration.
oO2c Oxygen sensor calibration point
oPress ON/OFF key for going to different pages.
At the end of the of the programming procedure on the display will be displayed “End” and the instrument will
display the oxygen content in the gas mix.
Threshold Alarms Setting
Press the ^ Prog key for more than two seconds, then release the key. On the display will appear “Pr” for two
seconds in order to advice the start of the programming procedure. Then will appear “AL1” for changing the value
of the minimum alarm threshold. The display will show “AL1” and the value of the alarm threshold alternatively.
The blinking digit shows the current cursor position.
Press the ^ Prog key for increasing the value (from 0 to 9).
Press the <Calib key to move the cursor to the next digit.
Press the On/Off key for accepting the value and jumping to AL2 threshold programming page.
Act as for AL1 to modify the AL2 maximum threshold to the desired value. If you want to exclude the minimum
alarm AL1 program it as 00.0. If you want to exclude the maximum alarm AL2 program it as 100.0.
Full Scale Value Setting
After the alarms concentration values setting, the instrument goes to “Fsc” page in order to change the analogic
full scale value of the instrument (if equipped with this feature). This is the Oxygen concentration at 20 mA on the
analogical output. 4 mA is the value at 0% of Oxygen concentration.
It is displayed alternatively “Fsc” and the value of the full scale. The blinking value is the actual changing value.
Press the ^ Prog key for increasing the value (from 0 to 9).
Press the <Calib key for going to the next value.
Press the On/Off key for accepting the value and jumping to the next program page.
Calibration Oxygen value
In this page it is possible to change the calibration point of the instrument. The display will show “O2c” and the
value of the oxygen calibration value alternatively. The blinking digit shows the current cursor position.
Press the ^ Prog key for increasing the value (from 0 to 9).
Press the <Calib key to move the cursor to the next digit.
Press the On/Off key for accepting the value and ending the programming procedures. On the display will appear
for two seconds “End”, then the instrument will show the Oxygen concentration reading.
In this page it is possible to define the oxygen percentage value that allows calibrating the oxygen sensor. This
value depends on the oxygen mix available. Every measure will be made referring to this calibration value. Wrong
calibration means wrong analysis.
Typically the calibration oxygen percentage value is 21,0%, because this value is the oxygen content in air. A
calibration in air is simple and do not need other well known oxygen gas mix.
Warning
The oxygen calibration value will be the same value of calibration set when the instrument is switched
on. During the warm up time if the oxygen percentage of the mixed gas flow is different from the value
of calibration set in the instrument, a failed calibration is obtained and a consequent wrong analysis
value will be read.

DE-OX® ZIP PRO Oxygen analyzer Draft Issue n. 1.2 of 27/02/11 page5
Threshold Alarms
Should the oxygen reading goes over the maximum or below the minimum threshold alarms (AL2 or AL1) the
instrument goes to alarm mode and it activates the relays output (open collector max 100mA) and the internal
buzzer. On the display will be shown the trespassed alarm and the actual measured value.
For stopping the buzzer song it is enough to press any key. In this event the instrument will remain in alarm
mode until the oxygen reading will be out of the thresholds values.
Oxygen Sensor Calibration
In the reading page, it is possible to calibrate the oxygen sensors, that, due of time, temperature, gas flow,
ambient pressure, could have variation of the measurement precision.
To do the calibration it is necessary to have a gas mix with well know and stated percentage of Oxygen.
The known percentage has to be set into the calibration Oxygen value in the programming procedure (see above).
For calibrating the instrument press the On/Off and <Calib keys at the same time for two seconds. On the display
will alternately appair “Cal” and Att” for 5 seconds, then the instrument, after displaying for few seconds the
calibration value in mV read during the calibration process, goes to the main reading page. It is possible to make
multiple analysis without calibrating the instrument every time.
Warning
During the calibration procedure, pay attention not to cover the two holes near the hose connection in
the rear of the instrument. The unit must be exposed to the known sample mixed gas (such as air or
pure oxygen) and calibrated consequently. If you calibrate with mixed gas flow, the flow must range
between 0,5 and 2 litres/min at atmospheric pressure and temperature, or DE-OX®ZIP PRO will yield a
wrong gas analysis. The unit must be kept steady and must not be shaken. Avoid change in temperature
between calibration gas and analysis gas.
Warning
Calibrating the sensors with wrong gas (with different values from the setting ones), will lead to
incorrect and very dangerous analysis.
The closest the calibration value is to the mixed gas percentage to be analyzed, the best and the fastest is the
DE-OX®ZIP PRO performance.
Warning
Whatever error in the calibration procedure will make mistake in the subsequent analysis.
Powering Off
For powering off the instrument, in the reading page press the On/Off key for more than 1 second. On the display
will appear “Off” and the instrument will power off.
Factory Reset
In case it is necessary to reset the instrument to the factory settings, power on the instrument pressing at the
same time for more than one second the On/Off and the <Calib keys. On the display will appear “res” and the
instrument will go to the reading page.
Warning
In case of reset, the instrument will delete all the alarms settings, the full scale value, any new
calibration value of the Oxygen sensor. Before using again the instrument, it may be necessary to
program again the alarm values, the full scale value, calibration value of the Oxygen sensor if changed.

DE-OX® ZIP PRO Oxygen analyzer Draft Issue n. 1.2 of 27/02/11 page6
All the analysis concentration shown on the display would be wrong. Wrong Oxygen analysis may lead
to death.
Note For Correct Oxygen Analysis
Before doing mixed gas analysis, connect the mixed gas hose (not supplied) to the adapter in the rear of the
instrument and let the gas flow goes through the internal oxygen sensor. The sensor, when coming in contact with
the mixed gas flow, gives an electrical signal. This signal is transmitted to the central unit and processed in order
to give the oxygen percentage information on the display. The oxygen analysis is made by comparing the
calibration value to the analysis value. The mixed gas flow that comes in contact with the sensor, must range from
0,5 to 2 litres/min (best 0,5 lit/min) at the same calibration pressure (typically ambient pressure 1 bar) and
temperature (Typically 20°C) or a wrong gas analysis will occur (preferably use a flow regulator with meter
connected to the mixed gas tank). Higher flow value or pressure or temperature variations, will cause wrong
analysis and may damage the sensor. Whatever error in the calibration procedure will make mistake in the
subsequent analysis. During the gas analysis, the unit must be kept steady and must not be shaken or submitted
to vibrations. Allow gas freely flows into the pipes.
During gas analysis, the oxygen percentage of the mixed gas being analyzed is available on the display. It is
possible to make more gas analysis without intermediary calibration.
It is possible to let DE-OX®ZIP PRO in ambient for ambient analysis Oxygen. In this case the reading will be
slower (up to 5 minutes).
Warning
When battery is nearly exhausted BAT appears on the display. In this case oxygen analysis is not be
reliable anymore.
Warning
NOOA and medical studies recommend not to expose to an oxygen partial pressure higher than 1.6 (ata)
because of serious personal injury including death. Refer to proper medical literature.
