Irradian Limited
L202PMS Photometer
8
The L202PMS photometer should always display a valid calibration label.
As with all measuring equipment a routine calibration is recommended,
typically annually, but with frequent use by a number of different users a
shorter recalibration period may be necessary
Irradian holds a number of tungsten halogen lamps and silicon
photodiodes which are routinely calibrated by the National Physics
Laboratory in the UK.
During manufacture the photopic filter is scanned with the filter glasses
selected for the best match to the CIE photopic response.
The meter is calibrated for illuminance at 100.00 ± 0.10 lux using a lamp
of colour temperature 2856K ± 50K and for luminance at 100.0 ± 0.3
cd.m
-2
using a uniform luminance standard source.
