3.2 Measurement
3.2.1 Routine checks and functional tests
1. Before daily use visually examine the hand unit and docking station, looking for any signs of
obvious damage. If you suspect the unit has been subjected to any impacts or moisture
ingress do not use the device. Contact Keeler or your local service centre for advice.
2. Keeler recommends performing a weekly self-test on the hand unit to confirm functionality.
This verifies operation of the puff generation system and the pressure sensor. To access the
self-test facility, follow these steps:
a. Power the unit up, ensuring it is plugged into the mains power supply.
b. Rest the unit on its side on a flat surface, such as on a desk. Do not hold the unit.
c. Press and hold the menu button and scroll through until the icon appears on
the
display.
d. Using the print or return button set this to ON.
e. Press and hold the menu button again to exit the menu (approximately 2 seconds).
f. The device will puff a number of times, and display a series of numbers as it progresses
through the test.
g. Once the self-test is complete the device will indicate that it has passed or failed on the
display.
