8. Remote Flowhead
The Micro flowhead can be set up to work remotely from the device. This
may be useful if the display needs to be monitored while the subject uses
the device.
1. Slide the flowhead away from the device from left to right. You
may need to push firmly to get it to move.
2. From the remote flowhead adapter kit, attach the device cap in
the space that was occupied by the flowhead.
3. Attach the remote flowhead adapter to the flowhead. This is done
by sliding the flow head into the grooves in the remote flowhead
adapter. Ensure this is fully pushed in.
4. Attach the remote flowhead to the port on the Micro Spirometer
cap using the flowhead connection tube.
5. It is recommended that an accuracy check is carried out before
the flowhead is used remotely or refitted to verify correct
operation and accuracy.
