ALPHA Touch - Instructions for Use
• Test Acceptance: Select whether to manually accept the tests
performed, or allow the device to determine test acceptability
(automatic).
• Graph Scale: Select the default graph scale.
• Posture: Select from ‘no posture selected’, ‘standing’ or ‘sitting’.
• Post VC Test: Selecting ‘off’ here means that selecting Post testing
brings the user directly to the FVC test screen. Post VC testing is ‘on’
by default where VC testing has been done in a pre-test session.
• Temperature: By selecting ‘on’ in the drop down list, the user is
offered the option to manually enter the ambient temperature as they
go into the VC or FVC test screens.
3.6.2. Database
To manage the available memory on the device, the Management tab tells you
how much subject and test session memory has been used up.
• Defragment: Device memory may become fragmented through long
use. To maximise available memory, select the defragment option.
Defragmentation may take several minutes to complete.
• Deletion: To delete a session, select the relevant box. The session
will be deleted from the device after being printed. (Either print to an
internal printer or sent to Vitalograph Reports). It is also possible to
‘Select Test Session(s)’ for deletion, or ‘Delete Subject(s)’ from the
device by pressing the relevant button using the touch panel LCD.
3.6.3. Calibration
The Vitalograph ALPHA Touch should never be outside accuracy limits unless
damaged or in a fault condition. In this event, see the fault-nding guide. In
normal use, calibration traceability certication is recommended as a part of
the routine annual service.
The Calibration Options menu contains the following:
• Calibration: To calibrate the device
• Precision Syringe: To select the volume of syringe used for calibration
• Linearity: To check linearity
• Accuracy Log: To view and print the accuracy log
Calibration
Calibration is not required for normal use. Calibration should only be conducted by,
or under the guidance of Vitalograph Service Agents. See contact details on p. 2.
1. Select ‘Calibration’ from the Calibration screen.
2. Pump air through the owhead to bring it to ambient temperature.
If the owhead has very recently been used for testing or has
come from a cold environment, its temperature should be
equilibrated with ambient by pumping air through it from the
syringe several times.
