User defined - If you do not want to use the standard measurement, you can give a new
value here. You must click the “ user defined ” button. The minimum value is 3.0 mm (8.0
mm if the dispenser is used) and the maximum 18.0 mm depending on the plate type and if
the dispenser is used or not. The height is measured from the bottom of the plate. This is
useful if you are measuring samples on filter paper and you need to optimise for the sample
being at the top or at the bottom of the wells.
Plate type
Select the one you want from the list of available plate types under the scroll bar. If the plate
size and/or format is different from the current one all the plates in the plate map will be
deleted and one plate of the selected type will appear. Make sure you select the plate type
before defining the plate map to avoid losing your settings.
Plate types are read from the Wallac 1420 database when the Protocol Editor is started so it
will not recognize plate types added while the Protocol Editor is open.
Note: the generic 8 x 12 plate selection does not check the height of the plate before a
measurement.
Note: If the type you selected has a different number of wells than the current one, all the
previous plates will be deleted and one plate of the selected type will appear.
Temperature level checking
This setting allows you to define what the target temperature should be when a plate is
measured. The plate heating controls are only enabled when used with a system that
supports the plate heating option.
Note: Setting this option will not activate the plate heating automatically, but it will cause a
warning to appear if the temperature differs significantly from what has been specified in
the protocol.
