Calibration Verification
The Vitalograph micro should never be outside accuracy limits
unless damaged or in a fault condition. In normal use, it is
recommended that a daily calibration verification is performed on
the device. ISO 26782 recommendations require that the difference
between the volume measured by the spirometer and the volume
pumped into the spirometer from a syringe is within 3%.
To complete a calibration verification:
1.
Select the Configuration button
on the main menu
screen.
2.
Select the calibration verification icon
.
3. Enter the Syringe volume
, serial number
and
ambient temperature using the touchscreen keypad.
4.
Connect the flowhead to the syringe and pump air through
the flowhead to bring it to ambient temperature. If the
flowhead has very recently been used for testing or has
come from a cold environment, pump air through it several
times to equilibrate its temperature.
