1. Instrument characteristic
KF-10 photometric calibrator is a source of luminous exitance (radiated
surface density of luminous flux) about 100lm/m2. It is designed to periodic
tests luxmeters made by SONOPAN. 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 KF-10 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 KF-10 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 luxmeters made by SONOPAN 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 luxmeters made by SONOPAN.

• 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. Photometric probes made by SONOPAN have standard
diameter Ø44mm and reception field Ø12.5mm.

• Power supply socket is used to connect AC adapter +12V 0.6A (see p.
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 KF-10 photometric calibrator (Fig. 2).
• Turn on the calibrator using key (Fig. 1), power indicator should
lights green.
• Wait till stability indicator starts blinking (Fig. 1).
• Place luxmeter probe in photometric probe socket.

• Measure the illuminance. The time in which the photometric probe is
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 .
6. Adjustment
KF-10 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
KF-10 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: MASCOT 5015
• Instruction manual
• Warranty card

9. Recommendations for instruments use
• KF-10 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.
10. Warranty and repairs
KF-10 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.
