Troubleshooting
34 Cary 50 Spectrophotometer Hardware Manual
The lamp is pulsing. This is indicated if the green power
indicator on the front of the instrument flashes (you should also
hear the monochromator and the filter wheel moving). You
should also turn the instrument on its side and look through the
small lamp viewing hole in the base of the instrument. If the lamp
is not pulsing you may have a hardware conflict.
The lamp is correctly aligned (see Page 25 for instructions on
aligning the lamp).
‘Calibrated’ appears on the ‘Calibration’ tab in System
Information. To open System Information, double-click the ‘Cary
WinUV’ folder (or the ‘UV Dissolution’ or ‘UV FO Dissolution’
folder) on the Windows desktop, and then double-click the
‘System Information’ icon. If the text reads ‘UnCalibrated’ on the
‘Calibration’ tabbed page, select ‘Initialize’. Wait for the
instrument to finish initializing and click ‘Calibrate’. When the
calibration routine finishes, the text will change to ‘Calibrated’.
Your instrument is now calibrated and is ready to use.
Repeat the Instrument Performance Test suite in Validate.
Eye and Shock Hazards
When operating, the lamp module emits high-intensity light, which can
damage eyes. To avoid eye damage, never operate the lamp module outside
the instrument.
The lamp module contains components operating at high voltages. To avoid
electric shock, NEVER disassemble the lamp module.
