Creating an Instrument Control Method 149
Autozero
Click this button to define the current signal as a zero level.
Scan, nm
This section is disabled for changes. It only provides information on how
the scan spectral interval is specified. Changes must be made from the
instrument setup window (Fig. 150 on page 102). It is not possible to
modify this function during a run.
Digital Channels (nm)
The number of channels that will be activated depends on how many
possibilities are given to set new values for the measuring wavelengths.
Pressing the WL Apply button forces the wavelength change on the
detector channels.
Digital Outs (Events)
Click the button to set up the digital outputs. Refer to the chapter
Instrument Setup – Pumps, Pump section Configuring Digital Outputs for
details. Click the DO Apply button to accept the settings. For detectors
without the feature of digital outputs this area is grayed and inaccessible.
The D2 lamp should be switched on manually from the direct control
window or using the Wake-Up option from the K-2600 before
starting the next working session. After power up, allow 30 minutes
for the lamp to stabilize before running samples that may require
sensitive measurements.
Instrument Status – Diode Array Detectors
(S 2600, DAD 2850, DAD 2800, K-2700 and Kontron DAD 540/545)

Monitor
Run Status
The status HOLD will be displayed when no program is running;
otherwise the Run Status displays a run time in minutes elapsed from the
start of the run.
Channel 1 / 2 / 3 / 4
The actual signal in the units which have been chosen in the detector
configuration dialog at the actual wavelength in nm is displayed for each
active channel.
Direct Control
The direct control option must be activated (see Fig. 249 on page 170).
