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 the Micro Medical 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 5 or
SpidaXpert software and patient details may be downloaded to the
Stored data may be printed to the integral thermal printer or to an
external HP printer using the USB cable supplied.

System options allow you to configure the following:
Height and weight units.

Predicted value sets.
Predicted area or line display.
Incentive display type.

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.

To load a new roll of thermal paper lift the paper cover using the side
levers, place the paper into the compartment as shown and close the
cover firmly. It is recommended that only Micro Medical thermal printer
paper (Cat No. PSA1600) is used with the MicroLab to avoid damage to
the thermal printer head.
To tear off the paper pull the paper towards you and to the right as shown

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 Hewlet Packard PCL3 and PCL3 enhanced
compatible USB printers. For a list of compatible printers refer to the
web site www.micromedical.co.uk or 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 approximately 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 5 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 5 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 5.
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 Micro Medical in convenient 81g containers, Cat
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
Micro Medical or an authorised agent if servicing is required.
