94 Creating an Instrument Control Method
Wavelength table
The wavelength table is a spreadsheet to enter your time (detector)
program. In the first row (at time 0.00 min), enter the initial wavelength(s)
in nm. The editing principle is the same as for the time (gradient)
program, described in the chapter Instrument Setup – Pumps, Pump
Program.
Configuring Events / Digital Outputs (UVD 2.1L, S2520 only)
This option is given only for the detectors UVD 2.1L and S 2550.
Configure the events by pressing the button which is displayed when
you place the cursor on the Events cell. The following dialog will appear.
Fig. 137 Configuring Digital Outputs
The Events (Digital Outputs) correspond to the outputs available on the
rear panel of the pump.
Select the state for each Event you want to set from the drop-down list.
The choices are Off (0), On (1), and Pulse (P). Refer to the pump’s user
manual for details about digital outputs parameters.
Use the All On or All Off buttons to switch all of the outputs either on or
off.
The standard version of the K-2001 detector is delivered with a
deuterium lamp as well as with 4 filters for the wavelengths 200,
220, 254, and 280 nm. For the K-2001 you can only use these
wavelengths in the time program. An optional tungsten-halogen
lamp is also available. Two additional wavelength filters of your
choice can also be built in. In this case you can use those
corresponding wavelengths in the time program.
The Start Input of the detectors K-2501 and S 2500 will also be used
to start an internal wave length program. If the detector is used for
synchronization input when working under software control, the
internal wave length program also will be started after receiving the
synchronization signal (trigger). As a result of this fact, the wave
length for the measurement may be different from the wave length
programmed in the detector’s instrument setup menu. Therefore, it
is highly recommend to delete all program lines of the detector’s
internal wave length program (please refer to the detector’s manual)
and for the first line (time 0), which cannot be deleted, to set the
wave length to the same value as in the software.
Refer to the section setting up a trigger on page 135 for details.
