Calibration
The UV1 instrument can be calibrated by adjustment of the zero and span using
the Aeroqual UV1 software. Please contact Aeroqual for instructions. Calibration
should be performed every six months or sooner if you suspect it may need it.
Maintenance
The UV1 O3 photometer should run without maintenance for extended periods if
the following procedures are followed:
a) Replace inlet filter regularly
This prevents dust entering the optical bench and coating the photodiodes which
would cause a decrease in sensitivity and possible non-linear response.
b) mount instrument in a clean and dry environment.
The enclosure is not water proof and water ingress could damage the electronics.
Several of the components inside the instrument have finite lifetimes and will
need replacement. These are documented in the table on the next page.
Safety
Caution: the photometer contains a UV lamp which may damage eyesight if
viewed unshielded. Always turn off the instrument before removing the
lamp housing.
