1. INTRODUCTION
The meter is an easy-to-use, precision photometric meter
designed for use in the field, laboratory, or production floor. The
meter measures luminous flux from source such as LED’s, small
lamps, and fibre-illuminators. The meter features a 75mm
diameter integrating shpere that collects the total light entering
the sphere measurement port.
The integrating is the ideal optical device for measuring luminous
flux from a source placed inside the sphere or just outside the
sphere sample port.
It meets CIE photopic spectral response, f ’
1
≦6%.
The meter is compact, tough and easy to handle owing to its
construction.
The light sensitive component used in the meter is a very
stable, long-life silicone photo diode and spectral response filter.

5. OPERATING INSTRUCTIONS
When press key to trun on the meter, the various settings
depend on the condition the meter was in before it was last
turned off.
5-1 Setting the Calibration Factor
Because the meter of the photopic filter is not perfect and small
adjustments to the collected radiation profile are needed to
improve the meter accuracy when measuring LED’s. These
adjustments are dependent on the peak wavelength and spectral
bandwidth of the test LED emission. The meter frimware makes
corrections to the photometric data through a user entered
calibration factors. If the test source is not an LED, the calibration
factor entry should be “1.00”.
1. Press keyto turn on the meter.
2. Press key first then press key to enter the
calibration factor setting mode.
3.Press  key to set to the desired calibration factor value.
4. Press key to store the value and exit this mode.

5-2 luminous Flux Measurement
1. Determine an appropriate entry sample port from the port adaptor
kit.
2. Press keyto turn on the meter.
3. Position the light source at the sample port. If you are measuring
LEDs and the meter includes a port adaptor, insert the lens into
the aperture as far as it will go. If no adaptor is available, position
the LED at the sample port so the tip of the lens protudes a few
millimeters beyond the outer enclosure of the sphere.
4. Press key to store the dark current flux.
5. Energize the light source and allow ample time for warm-up.
