Unused probes that are attached to the Raman Rxn2 analyzer should ALWAYS be capped to prevent stray
ambient light from entering the probe. Stray ambient light, whether from an uncapped probe or through
incomplete light shielding of the sample, may produce undesirable spectral interferences and result in calibration
failure or inaccuracy.
The beam emerging from the Rxn-20 probe is hazardous to the eye. Always secure the probe so that it is pointing
safely away from any personnel. Never handle the probe freely when it is operational.
5.2.4 Turning on the Raman Rxn2 analyzer
Press and release the Power button and turn the laser key switch to the ON position. The Power button blinks once
per second until Raman RunTime launches. The Laser Enable LED illuminates Red and the power switch illuminates
a solid Blue.
See Front panel → for more information about the Power button.
5.2.5 Turning off the Raman Rxn2 analyzer
Turning off the analyzer
There are two ways to properly turn off the Raman Rxn2 analyzer. One of these two methods should always be used
to turn off the analyzer unless it is unresponsive:
• Turning off the analyzer: method one. In Raman RunTime, navigate to Options > System > General and click
Shut Down. The analyzer turns off after about 5 seconds.
• Turning off the analyzer: method two (hardware option). Click and hold the Push button power switch until it
starts to blink (2 seconds). Release the Push button. The analyzer turns off after about 5 seconds.
Performing a hard shutdown
To perform a hard shutdown, there are two methods that can be used. Both hard shutdown options involve analyzer
hardware and are not options selected from Raman RunTime. They should only be used if Raman RunTime is
unresponsive:
• Performing a hard shutdown: method one. Click and hold the Push button power switch for at least 12
seconds until the analyzer powers down. Then release the Push button. After 2 seconds, the power switch begins
to blink; ignore and continue to hold down the Power button until analyzer powers down. Release the button.
• Performing a hard shutdown: method two. Unplug the analyzer.
See the Raman RunTime Operating Instructions (BA02180C) for more information.
