Test Sequence
Once the instrument responds to the gas, the dock will analyze the response
to determine if the instrument passes the bump test.
The gas detector will pass the bump test if the sensor response to the gas is
within 10% if the reading is lower than the expected sensor output or within
20% if the reading is higher than the expected sensor output (O
absolute). If the bump test is passed, the dock will proceed to the alarm tests.
If the instrument fails the bump test or if the instrument's calibration due
date has passed, the dock will automatically bypass the bump test and
proceed to a full instrument calibration without further input from the user.
Following successful bump test or calibration, the dock will test the
instrument's alarm systems.

If all alarms are operational, the following screen will be shown.
See Section 4.3 for further details on assessing test failures.
If all tests have been passed, the following screen will be shown.

Remove the instrument from the dock. The instrument is now fit for use.
Once the instrument is removed from the dock, the dock will reset itself
and prepare itself for the next instrument. In approximately 10 seconds
the display will show the READY screens. The dock is then ready for the
next instrument.
NOTE
The same instrument should not immediately be placed
back in the dock. It is recommended to wait three minutes
to allow the sensors time to recover.
