A manual fl ush must be performed if the auto fl ush is not selected. Failure to fl ush/purge fl uid
from the unit and hoses will result in anomalous results and can affect the cleanliness reading
achieved during the test.
NOTE
!
5.2.18 Home icon
Item 16, fi g. 5.3.
This icon shows in all screens. Selecting this at any point will revert
the unit to the home screen.
5.2.19 Test start/stop operation button
Item 17, fi g. 5.3.
Selecting this icon will start a test based on the parameters defi ned
by the other icons.
During a test the icon will ‘fi ll’ to show how much of the sample volume has been
performed.
During a test the text will change to ‘Emptying’ and the icon will ‘fi ll’ to show how
much of the emptying cycle has been performed.
Pressing the button during any part of either the Sample or Empty cycle will
immediately stop the test at this point, the pump will not automatically return to the
idle position.
If another test is started the pump will have to initially ‘home’ to fully empty the
pump. The icon will show ‘homing’ whilst the pump is purging and returning to the
idle position.
5.2.20 Manual fl ush operation button
Item 18, fi g. 5.3.
Selecting this icon will open the fl ush valve and allow a free fl ow
of fl uid through the unit. This allows for any previously used fl uids to be purged from
the hoses and the unit itself, thus reducing the risk of cross contamination as well as
providing relevant fl uid that is more indicative of what is occurring within the system
at the time of test. Whilst the fl ush cycle is running the text turns red and states
‘Flushing’ (see fi g. 5.30). To close the fl ush valve, press the button again.
Note: the fl ush button is disabled during a test (including the auto fl ush part of
the sequence). Should this cycle need to be stopped, press the Sampling button
(fi g. 5.26) to stop the test.
If the programmable auto fl ush is ignored i.e. set to zero, a manual fl ush will be
required. If no fl ush is performed the pump will immediately start to draw fl uid, this
will include any previously tested fl uid within the unit/hoses meaning the result will
not be indicative of the system cleanliness.
