1. Instrument characteristic
PCE-LMDC 200 photometric calibrator is a source of luminous
exitance (radiated surface density of luminous flux) about 100lm/m
2
. It is
designed to periodic tests luxmeters. The device generating illuminance
about 100lx in reception field of photometric probe. Optical system
and electronically controlled light source guarantee high stability of
luminous flux. Very long life of used light source makes not expected to
change it during the life of the device. Instrument is equipped with
automatic switch off function. Time of single period is about 1min.
Photometric calibrator is an indispensable tool for any laboratory
having implemented a quality system.
WARNING: Checking luxmeters using PCE-LMDC 200 photometric
calibrator can
not replace periodic calibration in accredited laboratory.
2. Technical specification
• Luminous exitance: M≈100lm/m
2
Illuminance in the reception field
of photometric probe: E≈100lx
• Light source color temperature: T
cp
≈3000K
• Illuminance stability:
for single working period: typically ±0,1% (max. ±0.3%)
after 3000 periods or 1 year ±1%
• Operating temperature: 0÷40°C
recommended operating temperature: 23±3°C
• Temperature coefficient: <0.02%/K
• Operating humidity: ≤80%
• Power supply AC adapter +12V 0.6A
Spectral distribution of PCE-LMDC 200 calibrator’s light source is
different than illuminant used during luxmeter calibration (typically
illuminant A). That causes indication deviation, which depends on
quality of the match of photometric probe spectral response to spectral
luminous efficiency of CIE standard photometric observer. For our lux
meters that deviation not exceed 0.03% for class A luxmeters and
0.15% for class B
