User guide for Cary 5000 absorption spectrometer
with external DRA 1800 attachment.
(last updated 03/17/2016)
This guide is for use of the Cary 5000 with the DRA only. For use without the DRA as a
standard transmission spectrometer see the User guide for Cary 5000 in absorption
mode.
Important warnings!
•
Do not unplug or plug in the external DRA attachment when the instrument is
on. This will ruin the detectors of the integrating sphere
•
Do not put white light into the DRA with the DRA electrically connected to the
Cary.
•
Minimize the amount of time that the integrating sphere is open. Long-term light
exposure hurt the detector over time.
