After successful calibration, the main screen
displays the absorbance measurement. MEASURE
ABSoRBAncE (ABS) on channel A at the preset
basic wavelength (254 nm). The wavelength now
can be set for the displayed channel directly from
this window, using the up and down arrows. During
a wavelength change the detector signal is not
automatically zeroed (Autozero). Autozero occurs
after pressing
ZeRO
on main panel.
The wavelength can be set by pressing the WL
key. Use the arrow keys to move the cursor left and
right and then up and down change the value. Press
enTeR
to confirm the selected wavelength. It is set
and overwrites the AcT value. Autozero the signal
and wait for the detector to stabilize.
Use the right arrow key to change the channel
selection (A, B, c, D). A different wavelength can
be set for each channel. Press the WL key to set the
wavelength for the selected channel. Use the left
arrow key to return to the previous screen.
Press the ZeRO key to put the detector in AUToZERo
(AZR) mode and reset the absorbance.
