6.2.8.2.
Autozero After WL Change
Here
can
be
in Menu/Parameters/Wavelength. ENABLE is set (Autozero is allowed) or DISABLE is set
(Autozero is not allowed). Default setting is ENABLE.
Autozero is not performed after change of wavelength with up/down arrows when ENABLE
is set.
6.3. Control
6.3.1. Optical Recalib
Calibration of optical unit is runs over after first start of light sources after unit switch-on, or it
can be initiated from this menu. If light sources are off and consequently turned on without unit
shutoff, optical unit calibration is not undertaken.
During optical unit calibration is set and controlled spectral setting of detector (wavelength).
Calibration of wavelength is based on spectral lines of hydrogen (656 nm and 486 nm) produced
by emission of deuterium lamp. First point of calibration (0 nm) is finding maximum light on zero
order (grating works as a mirror). Subsequently is found maximum light on spectral line 656 nm
and thereby is the detector calibrated. Verification of setting is done on spectral line 486 nm and if
it is not correct, detector displays a warning. At the end of calibration is performed autozero and
eventual deuterium lamp turnoff. If the use of tungsten light is set in detector menu
(Menu/Preferences/Lamps/Lamps use) than even in spite of that deuterium lamp is turned on
during optical unit calibration and turned off afterwards.
6.4. IO Config
6.4.1. Ethernet
In menu parts can be set possibilities of ethernet connection.
Note:
Prior to connecting the unit to corporate network, always contact local
network administrator and consult with him connecting parameters. This
way you will avoid network collision. For more information and
troubleshooting with ethernet devices connection, read document Manual-
Ethernet_devices, which is available upon request.
Ethernet interface supports communication speed 10/100 Mb/s. For connection can be used
common UTP cable (Cat 5e). Main communication proceeds on port 10001 and function of
automatic look up uses port 30718. The unit further supports the following services: DHCP client
(automatic IP address allocation), AUTOIP [automatic IP address 169.254.x.y. (x.y. ...random
generated numbers), when there is no available DHCP server in the network], web server (port 80)
and ICMP protocol (for connection test use tool PING).
