Cleaning the Transducer
Consumables / supporting products
The MicroLab is mains/battery operated portable spirometer with the
unique combination of ease of use and sophistication.
Ease of use is assured through the use of context sensitive help screens,
accessed at a touch of a button, that explain every MicroLab feature.
The MicroLab uses a Digital Volume Transducer, an extremely stable form
of volume transducer, which measures expired air directly at B.T.P.S (Body
Temperature and Pressure with Saturated water vapour) thus avoiding the
inaccuracies of temperature corrections. The transducer is insensitive to
the effects of condensation and temperature and avoids the need for
individual calibration prior to performing a test.
Test results may be uploaded to a PC using the optional SPIDA software
and patient details may be downloaded to the MicroLab.
Stored data may be printed to the integral thermal printer or to an
external USB printer.
The MicroLab utilizes a single patient use disposable mouthpiece that
must be disposed of after use.
The MicroLab provides a suggested interpretation that must be
supported by clinical judgement.
The MicroLab uses a touch screen
with icons representing each
function available. A stylus, housed
in the left hand side of the unit, is
provided for icon screen activation.
Touch the displayed time to adjust
time and date.
Unused icons may be disabled by
touching the blue background and
selecting from the list displayed.

The ‘Customise’ option from the main menu may be used to configure
many of the features of your MicroLab and are divided into system and
System options allow you to configure the following:
Height and weight units.
Colour or monochrome printing (on external printer).
Personalised printout heading.
Spirometry options allow you to configure the following:
Relaxed spirometry mode (with or without tidal breathing).
Predicted value sets.
Predicted area or line display.
Incentive display type.
Best test criteria
Interpretation and Lung Age indication.
Dyspnoea score and smoking status.
Calibration reminder and manual temperature adjustment.
Note that when the language is selected, the height and weight units, date
format, and date separator will be automatically changed. However this
automatic selection may be overridden manually.
Administration mode allows the
administrator to restrict the
availability of functions to the user
by disabling icons on the main
menu. For example, after the unit
has been configured to the
disabling of the ‘Customise’ icon
adjustment by the user. Similarly,
Management’ icon will prevent the
user from deleting any patient
details or test results.

Using the USB cable provided connect the mini A/B socket on the right
hand side of the MicroLab to the input socket on the printer. The
MicroLab is compatible with the following Hewlet Packard PCL3 and PCL3
enhanced compatible USB printers. For a list of compatible printers
contact your local dealer
It is recommended that during printing the batteries are on charge with
the unit connected to the mains adapter.
NOTE: Keep the printer out of reach of the patient at all times.
The MicroLab’s internal batteries are discharged when shipped from the
factory and should be fully charged on first use. Plug the AC adapter into
the mains supply and plug the adapter output plug into the power input
socket on the right hand side of the instrument. The orange charging light
next to the power input socket will flash to indicate charging and will turn
on constantly to indicate full charge.
The batteries will take about 4 hours to become fully charged.
Note: Use only the AC adapter supplied. Use of any other type may
cause permanent damage to the MicroLab and cause a fire or electrical
hazard. Do not plug in and remove the power lead from the AC adapter
PC connection using SPIDA 5
SPIDA is an easy to use PC based windows application that interfaces to
the MicroLab via a USB or serial port. It incorporates a database into
which patient details can be entered and downloaded to the MicroLab or
test results may be uploaded from the MicroLab to the PC.
Using SPIDA and the MicroLab, live blows can be performed with the PC
directly controlling the operation of the MicroLab.
The results and graphs produced are displayed directly on the PC screen.
The spirometer is connected from the serial or USB port on the PC, to
the port on the right hand side of the instrument using the USB or serial
cable provided with SPIDA.
Note: the MicroLab should only be connected to a computer that is
manufactured in accordance with EN60950 1992/1993 – ‘Safety of
Information Technology Equipment including Electrical Business
Keep the PC out of reach of the patient at all times.
It is recommended that whilst the unit is connected to a computer the
mains adapter is used.
Looking after your Spirometer
Please observe the following precautions:
• Do not touch the screen with fingers. Use only the stylus provided.
• Use only a damp, lint free, cloth to clean the screen.
• Do not keep the spirometer in a damp place or expose it to extremes
• Do not direct the transducer holder towards a strong light source
whilst operating the spirometer.
• Check the AC charger for compatibility with local power rating.
Cleaning the Transducer
The transducer requires no routine maintenance or servicing. However, if
you wish to sterilise or clean the transducer it may be removed by means
of the following procedure:
1 Rotating the turbine transducer anti-clockwise until the locating pip
lines up with the small rectangular cut-out in the housing as shown below.
2 Gently pull the transducer away from the housing.
3 The transducer may now be immersed in warm soapy water for
routine cleaning or immersed in cold sterilising solutions e.g. Perasafe for a
maximum of 10 minutes (Alcohol and chloride solutions should be
avoided). After cleaning/sterilising, the transducer should be rinsed briefly
in distilled water and dried.
Perasafe is available from Cardinal Health in convenient 81g containers.
4 Re-assemble the mouthpiece holder.
There is no routine maintenance required for the MicroLab and there are
no user serviceable parts in this instrument. Please return the unit to
Cardinal Health or an authorised agent if servicing is required.
In the unlikely event that the display ‘freezes’ and the unit does not
respond to any key presses, hold the on/off button down for 10 seconds
until the unit switches off and then turn on again.
