λ
(Wavelength)
Use to set the Wavelength.
2 Range Use to set the sensitivity for output to a recorder.
3 RSP/PW This parameter allows you to set the amount of smooth-
ing to apply to the chromatogram. For guidelines on
choosing an appropriate response time, see the “Detector
Response Time” topic in Chapter 8, Principles. The
parameter can be entered in either Peak Width (PW) or
Response Time (RSP). You select either PW or RSP when
you configure the detector. For more information, see
Chapter 6, Configuring the Detector. Once you select PW
or RSP, the detector displays the available values on the
softkeys. For response time, select a value that is approx-
imately 20% of the peak width at half height of the nar-
rowest peak of interest. For peak width, select a value
that is approximately equal to the peak width at half
height of the narrowest peak of interest.
4 TE1 Indicates “Relay TE 1.” Press the arrow key to set relay
TE1. Timed events control the relay contact closures
which in turn control auxiliary instruments (fraction col-
lector, autosampler, etc.). When actuated, the relays can
be closed, opened or closed for about two seconds, then
reopen.
TE2 Indicates “Timed Event 2.” Press the arrow key to set
relay TE2.
5 MARK Softkey Use to put a mark on the recorder output.
