Test Status Text Conditions
In Progress (delay) Test operating during initial delay time
In Progress Test operating after initial delay time

7.5 Power Failure During Test
The door remains locked after a power failure. The key switch can be used
to override the lock, but this feature is not recommended because of
danger to the operator.
Note that when power returns the display shows a message to indicate the power was
interrupted during a test, see Fig 41. The test will re-start automatically, once the
control software has started. The test results should be discarded.
If the sample temperature within the chamber is under 120 °C, or if there is no sample
present in the chamber, then it is permissible to immediately cancel the test using the
procedure given in section 7.7.

The end of the test is determined by the three recipe parameters, see Fig 42. The
system can be set to use either Min % Weight Change or Constant Mass Limit; Fig 42.
shows the example where Constant Mass Limit has been selected. For a test to end, the
weight variation must be less than or equal to the set limit during the period defined by
Constant Weight Time.
Note; the monitoring for the end of test conditions being met will not start until the
Initial Delay Time, defined in the recipe, has expired. This setting has a range from 0
to 60 minutes.
