LAMPLLL.IRX - LAMP IRRADIANCE FILE
Lamp Irradiance files, generated at the factory, tabulate the UV irradiance of
First row - lamp identification number
Second row - distance between lamp filament and Teflon diffuser
Now the file splits into 2 columns:
First column - wavelength in Angstroms from 2865A to 3630A in 0.6nm Increments.
Second column - irradiance in milli watts per square meter.
OP_ST.NNN - OPERATING STATE FILE
The operating state file controls many of the operating parameters of the Brewer. The left column
lists the actual value written in the OP_ST.nnn file. The middle column is the BASIC variable name
used in the Brewer software to contain this value, and the right column is a description of the value's
meaning.
