The measuring probe can also be connected to LM10 via 80 cm long connecting cable. Select the
corresponding measurement unction via the Selection button.
The in luences o other light sources should be avoided i a single lamp is to be measured. When
measuring the compact luorescent lights (energy saving lamps), it must be taken into account that
they attain their ull light intensity a ter ew minutes.
6.2. Measurement of the visi le spectrum with the measuring pro e VL10
The measuring probe VL10 provided with the Lightmeter LM10
combines the measurement o the illumination intensity E in
Lux, the licker rate in % and the licker requency up to 400
kHz using the quick precision ampli ier.
The maximum values (peak hold) o illumination intensity and
licker rate can be displayed using the Selection button. The
maximum values can be reset with the Record button.
The measured spectrum covers the visible range rom 480 nm
to 660 nm.
The spectral sensitivity V(λ) o the measuring probe is adjusted
to that o the human eye.

6.3. Calculation of flicker component
LM10 calculates the licker component according to the ollowing selectible procedures:
Ripple content:
In accordance with the Standard of
Bui ding Bio ogy Testing Methods
SBM-2015.
Flicker%:
In accordance with IESNA.
Luminous lux ϕ in Lumen (lm)
6.4. Measuring the flickering rate and flickering frequency
The visible spectrum must be measured using the measuring probe VL10.
To precisely measure the licker rate and licker requency o a lamp, the in luence o other light
sources including daylight must be avoided. The measurement must there ore be carried out in a
dark room.
The LM10 must be aligned directly to the lamp using the measuring probe VL10 and get it closer
till the measured values are stable.

Φmax+Φmin ∗100%

Lightmeter LM10
In case o incandescent lamps and halogen lamps, the licker requency is always 100 Hz and the
lickering rate is rom 15% to 25%. Low-volt halogen lamps with electronic power supply are an
exception.
Brightness of a compact f uorescent amp (F icker rate 31%, f icker frequency 49 Hz)
Compact luorescent lamps also known as energy-saving lamps have a licker requency in the
range rom approx. 20 kHz to 150 kHz due to the integrated electronic power supply. The lick-
ering rate is typically rom 20% to 40%.
Brightness of an LED amp (F icker rate 100%, f icker frequency 49 Hz)
As the brightness o an LED responds almost without lag to its operating current, a general state-
ment on the licker rate and licker requency or these lamps is not possible.The licker rate can lie
between 0% to 100%, depending on the voltage source used (power supply). Flickering requecies
o 50 Hz to a ew 100 kHz are possible. Hence, the quality o the voltage source is o greater
importance in LED lamps.
