3-2 Using the Detector
Starting the detector
Initializing the detector
Before you start the detector, be sure the power cord is properly installed at
the detector’s rear panel and plugged into the power source.
To start the detector, press the on/off switch on its front, lower-right-hand
corner (see the figure “Waters 2475 Multi λ Fluorescence Detector” on
page 1-7 ).
The detector beeps three times, displays the message “Booting System...
Please Wait (Service Keypad Inputs Accessible for 6 sec.),” and runs a series of
startup diagnostic tests.
Tip:
Service keypad inputs are coded for use only by Waters service engineers
for troubleshooting purposes.
The detector displays the following messages:
1. Initializing grating
2. Initializing system
3. Lighting lamp
4. Warmup time left (counts down from five minutes)
Warning:
• Always observe Good Laboratory Practices when you use this
equipment and when you work with solvents and test solutions.
Know the chemical and physical properties of the solvents and test
solutions you use. See the Material Safety Data Sheet for each
solvent and test solution in use.
• Using incompatible solvents can cause severe damage to the
instrument and injury to the operator. Refer to Appendix C for more
information.
Warning:
Explosion hazard. The flash point is the lowest temperature at
which a flame can propagate through the vapor of a combustible
material to its liquid surface. A chemical’s flash point is determined by
the vapor pressure of the liquid. Only when a sufficiently high
concentration is reached can a solvent vapor support combustion.
