1. Instrument characteristic

PCE-LMDC 200 photometric calibrator is a source of luminous
exitance (radiated surface density of luminous flux) about 100lm/m2. 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/m2
Illuminance in the reception field
of photometric probe: E≈100lx

• Light source color temperature: Tcp≈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

luxmeters. The influence of the color temperature of calibrator’s
light source is negligible for our lux meters.

tability indicator

• Power switch is used to turning on / on the instrument.

• Power indicator if the voltage of the power source is in the operating

range – it lights green. If the voltage is too low –

it lights red (calibrator

should not be used in that case).

• Stability indicator should blink in normal operation. It means that
electronic control of light source works properly and illuminance is as
described in technical specification. Otherwise illuminance is
unspecified.

• Photometric probe socket is used to place photometric probe which is
being checked. Our photometric probes have standard diameter Ø44mm
and reception field Ø12.5mm.

7. Power supply).

• Adjustment blockade is secured against accidental use and it is needed
during calibrator’s calibration and adjustment made by manufacturer or
accredited laboratory (see p. 6. Adjustment).

5. Operation

• Turn on luxmeter under test then check and eventually correct the zero
with photometric probe covered.

• Connect AC adapter to PCE-LMDC 200

• Turn on the calibrator using key

being held in calibrator’s socket should not exceeded several seconds
(max. 1 single working period of the calibrator), see also
p. 9. Recommendations for instruments use.

• Turn off the calibrator using key

Adjustment

6.

LMDC 200 photometric calibrator has been initially adjusted by manufacturer

.

in reference to factory standard (calibrated class A luxmeter) and
adjustment blockade (Fig. 2) was sealed. Adjustment is possible but
should be conducted only if the user have technical capabilities to do that.
For that purpose remove the seal and loosen the screw blocking

photometric probe socket. The screw is accessible by hole marked ,
located on the back panel (Fig. 2). Turn photometric probe socket to
change luminous exitance of the calibrator. After finishing adjustment
firmly fasten the blocking screw.

7. Power supply

PCE-LMDC 200 photometric calibrator is powered by a stabilized AC
adaptor with +12V output voltage and 0.6A max current.

Only AC adaptor supplied by the manufacturer should be used to
poring the instrument

WARNING: AC adaptor has capability to reverse the polarity. Positive

polarity should be set according to marking on back panel of
the calibrator. Reversing the polarity will not damage the
calibrator but instrument will not be working properly.

8. Accessories

• AC Adapter

• Instruction manual

• Wooden storage box

9. Recommendations for instruments use

• PCE-LMDC 200 photometric calibrator contains sensitive optical
elements and requires careful handling. It is forbidden to expose
instrument on falls, shakes neither any other factors which can cause
mechanical damages.

• Photometric probe socket cover should be removed only on measuring
time. Photometric probe should be clean before placing it in socket.

• To prevent photometric probe heating, the time in which the
photometric probe is being held in calibrator’s socket should not
exceeded several seconds (recommended time is 15 seconds, max. 1
single working period of the calibrator).

• In case of needing clean the lens use clean (degreased and devoid of
impregnates) and soft brush holding the calibrator in an inverted
position (photometric probe socket head down)

• It is necessary to protect instrument from wet and aggressive chemical
factors that can damage instrument elements.

• Only AC adaptor supplied by the manufacturer should be used to
powering the instrument.

• Adjustment should be conducted only if the user have technical
capabilities to do that.

• The instrument should be stored and transported only in original
packaging.

Warranty and repairs

10.

PCE-LMDC 200 photometric calibrator is shipped with one year warranty.
It does not require any special maintenance treatment.

All repairs of the instruments are performed by the manufacturer.
