Instrument Performance Testing

Problem

The results of your instrument performance tests do not meet specifications (the
results obtained during factory testing are included in the packing crate with the
instrument).

Solution

Check the following:
The sample compartment is empty.
•
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 while the
instrument is scanning.
The lamp is correctly aligned (refer to the Cary WinUV Help for instructions on
•
aligning the lamp).
'Uncalibrated' appears on the 'Calibration' tab in System Information. To open
•
System Information, double-click the Cary WinUV folder on the computer
desktop, and then double-click on the 'System Information' icon. If the text
reads 'Uncalibrated' on the 'Calibration' tab turn the Cary 60 off and then back
on again. Wait for the instrument to finish initializing and calibrating. 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.

Wavelength Calibration

Problem
The position of an absorption (transmission or reflectance) peak appears to shift
over a prolonged period of time.
