MKIII OPERATOR’S MANUAL

UV Lamp Scan

UL is a test command that results in a UV scan being performed with a Lamp (rather than
the sky) being the source of radiation.
The zenith prism is rotated to the UV dome, FW#2 is set to the 1 position, FW#1 is set to the
3 position, the iris is opened, and the tracker is rotated to the sun. The operator is asked for
lamp number, and lamp-diffuser separation, and the radiation intensity is measured in 1.5nm
increments over the UVB range.
Data is stored in a ULJJJYY.nnn file.
See also Appendix A.

UV(B) Observation

UV results in the irradiance over the “B” region of the spectrum to be measured.
The zenith prism is rotated to the UV dome, FW#2 is set to the 1 position, FW#1 is set to the
3 position, the iris is opened, and the tracker is pointed toward the sun. The UV spectrum is
then scanned in steps of 0.5nm from 290nm to 325nm, and then back to 290 nm.
The data is appended to a UVJJJYY.nnn data file.
When scanning is complete, a calculation of the UVB/UVA McKinley- Diffey weighted
irradiance is computed, sent to the printer and to the monitor screen, and appended to the
DUVJJJYY.nnn data file. A correction is made to the Diffey action spectrum to include the
effects of the UVA region 325-400nm).

UVSUM UV Data Summary

This command initiates activity which processes and prints the daily summary of all UV
measurements made during that day. DUV values are also calculated for each measurement
and data is appended to the UVOAVG.nnn file.
See also Appendix A.

Extended UV Wavelength Scan

UX causes the irradiance over the 286.5nm to 363nm range to be measured in 0.5nm
increments in ascending wavelength. The zenith prism is rotated to the UV dome, FW#2 is
set to the 1 position, FW#1 is set to the 0 position, the iris is opened, and the tracker is
pointed toward the sun. The UV spectrum is scanned, and the data is appended to a
UVJJJYY.nnn data file When scanning is complete, a calculation of the UVB / UVA
McKinley- Diffey weighted irradiance is computed, output to the printer and to the monitor
screen, and appended to the DUVJJJYY.nnn data file.
See also Appendix A.

W0-W4 Time delays

These five commands result in time delays of 1, 5, 10, 20, and 30 minutes respectively and
can be used in command strings or in schedules.

Extended External Lamp Scan

XL is a test command that results in an extended UV scan being performed with a Lamp
(rather than the sky) as the source of radiation.
The zenith prism is rotated to the UV dome, FW#2 is set to the 1 position, FW#1 is set to the
3 position, the iris is opened, and the Tracker is rotated to the sun. The operator is asked for
lamp number and lamp-diffuser separation, and the radiation intensity is measured in 0.5nm
increments over the extended UV range. Data is sampled for 30 cycle time increments
through slit #1 for wavelengths less than 300nm and 20 cycle time increments through slit #5
for higher wavelengths.
Data is stored in an XLJJJYY.nnn file and is normalised to 1 cycle observations.
