Creating an Instrument Control Method 93
Instrument Setup – UV Detectors (UVD 2.1L, UVD 2.1S, S 2520,
S 2500, K-2001, K-2501)
For the detectors K-2001/2501 you should set in the detector setup
screen / EXT.CONTROL menu the keyboard mode to be able to
control the wavelength from the ChromGate ® software.
The detector basic settings, as time constant, sampling rate etc. are
described on page 91.
Fig. 136 UV Detector setup window
Autozero at start
Check the Autozero field if you wish the signal to be zeroed at the
moment a measurement is started (to define the current signal as the
baseline).
Autozero at WL change
No access to this option. The grayed area is only a reminder, that the
autozero will take place at any wavelength change during a run.
Lamp OFF at the end of run
Check the lamp OFF box to switch off the detector lamp after a
measurement is finished. This option may be used for the shutdown
methods.
Detectors UVD 2.1L, S 2520 and 2550: If the lamp was switched off
by the method and you switch off the detector then, on the next
detector start the lamp is still off; it must be switched on manually
in the detector’s own setup or with the software via Instrument
Status – Direct Control.
[Action] at the end of run (UVD 2.1L, UVD 2.1S, S2520 only)
The detectors S UVD 2.1L, UVD 2.1S and S 2520 allow not only to switch
off the lamp at the end of run, but also to switch the device into Standby.
You should switch the lamp on manually before you start the next
working session. After power up, allow 30 minutes for the lamp to
stabilize before running samples that may require sensitive
measurements.
