LAMP_LLL.nnn - Lamp File
The Lamp file is created at the factory by an initial Quick Scan.
Subsequent QS scans append data to LAMP_LLL.nnn, using the first line as a reference.

Column Description
1

Julian date

Distance from lamp filament to PTFE diffuser

pmt temperature

Dark count

5-15

Intensities at 11 wavelengths

DUV calculation based on the lamp intensities

QL_LLL.nnn - Lamp File

The Lamp file is created at the factory by an initial Quick Lamp Scan.
Subsequent QL scans append data to QL__LLL.nnn, using the first line as a reference.

Column Description
1

Total amount of wavelengths measured

Julian date

Distance from lamp filament to PTFE diffuser

pmt temperature

Dark count

Average percentage deviation compared to top reference measurement

7-30

Corrected intensities at 12 wavelengths (for MKII)

Time scan finished (for MKII)

7-54

Corrected intensities at 24 wavelengths (for MKIII and MKIV)

Time scan finished (for MKIII and MKIV)

LAMPLLL.IRX - Lamp Irradiance File

Lamp Irradiance files, generated at the factory, tabulate the UV irradiance of the UV test lamps.

First row - lamp identification number

Second row - distance between lamp filament and PTFE diffuser

Now the file splits into 2 columns:

First column - wavelength in Angstroms from 2865A to 3630A in 0.5nm Increments.

Second column - irradiance in milli watts per square metre.

PUX, PUF, PUV, PUA: Processed UV files
First row - decimal hours from 00:00 (GMT) Header for each scan includes date, starting time
(hour), ending time (hour), zenith angle, latitude, longitude, location name, instrument # and
measurement type, Row 2 column 1 - GMT time in minutes, column 2 - Wavelength (Angstroms),
column 3 - irradiance (W/m

/nm or mW/m

/nm, depending on selection during processing).

PXL: Processed lamp files

First row - Lamp Number

Row 2 - distance in centimeters

Column 1 Row 3 - Wavelength (Angstroms)

Row 4 - irradiance (mW/m

/nm)
