CW-Lamp filters
You can select the CW-lamp filter from the drop-down list of available filters. See the
chapter on Filters for more information about how to define filters.
Factory pre-set CW-lamp filter names begin with a letter indicating the technology for
which they are to be used:
P is for photometry. After the letter comes the wavelength.
Excitation aperture (Wallac 1420-040/041 only)
There are three sizes of excitation aperture controlling the size of the incident light beam.
You can select with the option buttons Small, Normal or Large. Normal is the default.
Reading time
This parameter determines how long the sample is read to determine the absorbance.
Second measurement
In the case where you want to make measurements with two filters, you can click this check
box and then set the parameter
CW-Lamp filter - It has the same options as the parameter
with the same name above. When you select this, two measurements are made, the first with
the normal settings and the second with this new setting. The change is automatic.
