1. Description
λ Key
Selects the wavelength to be used for reading the microplate manually. The control panel
does not display the wavelength selected through SoftMax Pro.
Pressing the up or down arrow key scrolls up or down through the available wavelengths,
starting at the previous setting:
>
Pressing the up (S) or down (T) arrow once increments or decrements the displayed
wavelength by 1 nm.
>
Pressing and holding either arrow increments or decrements the displayed wavelength
by 10 nm until it is released.
Ref Key
A reading of buffer, water, or air taken in the cuvette that is used as I
0
to calculate
Absorbance or % Transmittance. If no reference reading is taken, the instrument uses the
I
0
values stored in the NVRAM (non-volatile memory) of the instrument.
Read Cuvette Key
Initiates the sample reading of the cuvette.
%T/A Key
A toggle switch used to display cuvette data as percent transmission or absorbance.
Drawer key
The key opens and closes the microplate drawer.
1.2.2. THE MICROPLATE DRAWER
The microplate drawer is located on the right side of the instrument and slides in and out
of the reading chamber. An internal latch positions the microplate in the drawer as it
closes (allowing for better robot integration—no springs or clips are used).
The drawer remains in the reading chamber during read cycles.
