Description
The different options for when to start timing
the filtration process:
•
When pressure is achieved
•
When the vacuum pump starts
The duration, in seconds, that you want to leave
the vacuum on. At the end of the period, the
vacuum will turn off.
The different options for whether to have the
Bravo gripper hold down the filter plate when
the vacuum is turned on to ensure a secure
vacuum seal:
•
None
•
Tap down. The Bravo gripper will hold
down the filter plate from the top only for
the time period specified in the Duration for
tap down parameter.
•
Hold down. The Bravo gripper will hold
down the filter plate from the top for the
duration of the task.
Note: If you select None or Tap down, the
protocol can perform other tasks in parallel.
Concurrent operation is not an option if you
select Hold down.
The length of time, in seconds, that the Bravo
gripper will hold down the filter plate if the Tap
down option is selected.
The length of time, in seconds, to allow the
vacuum to reach the specified target pressure.
An error message displays if the target
pressure is not reached within the time
specified.
The desired unit of measure: mbar, Torr, hPa,
mmHg, cmHg, or inHg.
IMPORTANT
The Pump Pressure Units
setting in the profile configuration must match
the units set at the VARIO pump controller in
order for the software to convert the values to
different pressure units.
