2 Introduction
The OXYBABY®is an ergonomic, cordless, one-hand oxygen and carbon dioxide analyser, used
for the preventive inspection of the shelf life of a food packed in modified atmosphere packaging
(MAP). It has a measuring range of 0 per cent by volume to 100 % per cent by volume O2or CO2in
non-combustible and non-aggressive gases, and can be used for determining the carbon dioxide
content as well as the residual oxygen content in food packaging.
Caution!
The device is not designed to be used in potentially explosive areas and may not be used
for measurements which involve burnable gases.
The OXYBABY®comes with an internal data memory for readings (ring buffer, for maximum num-
ber of data records refer to the Chapter on Technical data 14), which are retained in the memory
even when the device is switched off.
If the rechargeable battery is spent,
- the stored data is retained (e.g. product, user, manufacturing date),
- the data and time are retained for approx. one week (buffer capacitor).
The measured values can be copied to your PC using the optionally-available software for the
WITT Logger.
The OXYBABY®is equipped with a needle cover to protect the user.
Because of the variations in equipment your Oxybaby®may differ somewhat from these instruc-
tions.
2.1 Which symbols have been used?

4 Operating principle
The device uses the integrated pump to suck-in a gas sample from the packaging to be inspected
and routes it to an O2and a CO2measuring cell.
The O2content in the aspirated gas mixture generates, in the chemical measuring cell, a weak
electrical voltage proportionate to the O2content. This voltage is measured and converted to form a
concentration value, which is then shown on the display.
The CO2measuring cell operates according to the infrared absorption principle.
Once the analysis is over, the O2and CO2concentration levels are stored with the date and time.
The internal memory is designed as a ring buffer (maximum number of stored measuring data: see
Technical data).
Everytime the memory is full, and a new measured value is stored, the oldest measured value is
overwritten. The assigned memory location is displayed by a segment bar at the top of the display.
The O2measuring cell of the Oxybaby®has a service life of approx. 1.5 to 2 years with an
O2content of 21 % per cent by volume. If the O2content is higher than 21 % per cent by volume,
the service life for the O2measuring cell is reduced (See Technical data for details).
The CO2measuring cell is non-wearing.
Oxybaby®is equipped with automatic pressure compensation, which serves to prevent any falsified
test results through changing ambient pressures or gas pressures in the packaging.

"Sample Hold" operating mode (sample measurement)
After the start of the measurement (see Chapter 7) the measuring program then runs automatically.
A gas sample is taken from the packaging and the
O2/CO2concentration level measured. Once the measuring time process has ended (see Techn.
data) the gas sample is automatically stopped.
The measured O2/CO2concentration level is automatically stored once the measurement is over
along with date and time (incl. product designation, inspector and production line).
"Permanent“ operating mode
Once the measurement has started, (see Chapter 7) gas is continuously sampled and the O2/CO2
concentration level is measured.
The measurement can be stopped at any given time with .
The last determined measured value is automatically stored along with date and time
(incl. product designation, inspector and production line).

6 Power supply
The power supply is provided by means of a rechargeable battery pack with three integrated, re-
chargeable batteries (Type: see Technical data). The service life of the rechargeable battery pack
is dependent on the ambient conditions and the number of charge cycles.
If required, the rechargeable battery pack can be replaced. Only genuine WITT spare parts should
be used here, a new rechargeable battery pack can be ordered from WITT-Gasetechnik .
The charge status of the rechargeable batteries is denoted by a battery symbol in the top right cor-
ner of the display, a dark battery indicates: fully charged. The Oxybaby®switches off when the
rechargeable battery is spent.
 If the rechargeable battery charge is no longer sufficient to perform a reliable measurement,
a warning message is shown on the display. In such an instance do not perform any more
analyses, as the measurement accuracy may be impaired.
 You can easily switch between rechargeable battery mode and power supply unit mode
when operating it.
6.1 Charging rechargeable batteries

en Close
 Recommendation!
Open the needle cover immediately before a measurement and then close it again immedi-
ately after each measurement.
7.3 Conducting measurements
Caution!
Adapt the OXYBABY®before the measurement to any changes in climate, to avoid any falsi-
fied test results (see Technical data).
This also applies to packaging which is stored at higher or lower temperatures than the OXY-
BABY®.
 We advise calibrating the OXYBABY®before the first measurement
(see Chapter 8.9 and 9).
 You can increase measuring accuracy by
 performing two measurements at a very low temperature or by extending the measuring
time.
 performing two measurements or extending the measuring time on successive meas-
urements on packages with very different gas concentration levels.
7.3.1 Sample Hold measurement
 Change to the “sample hold” operating mode if required (see Chapter 8.4).
 Select any product, user or line (production line) (see Chapter 8)
 Stick foam pads onto the packaging that you wish to measure.
This seals the pierced position.
 Open the needle cover (see 7.2)
 Pierce the packaging through the foam pad.
Caution!
Do not jab into the fluid or the packaged product. Otherwise the OXYBABY will be soiled,
the needle or hose may clog up or the sensor may be damaged.
 Start measurement with .
The remaining measuring time is shown by the OXYBABY®at the top right of the display.
You can extend the measuring time during the measurement.
 Press key again, the measurement continues, if you press the key again briefly.
 Close the needle cover (see 7.2)
The last current measurement is shown on the display.
 The measurement ends automatically in the Sample Hold mode .
At very low temperatures, you may also need to run two measurements to increase the
measurement accuracy.
