INTRODUCTION
This Sper Scientic LED light meter with color temperature
correction (model 850006) is specically designed to measure
modern LED bulbs over the wide range of color-temperature
varieties commercially available in today’s lighting industry.
This unique meter includes all the features of a standard
LED light meter and also has individual channels specically
designed to measure di󰀨erent color-temperatures of LED light
bulbs. A simple intuitive keypad allows you to begin using the
device immediately in Foot Candles (FC), Lux (Lx), or Luminous
Intensity (CD). The user can preset the source distance for an
even more thorough analysis, showing readings on the large
LCD display. With a Min/Max/Average, Auto-Ranging Intensity,
99-point internal memory, Hold function, and a single-button
zero calibration, this meter covers every available feature of
competitive light meters. Comes with a universal tripod screw
in a compact carrying case with 9V battery, lens cover, and
instructions.

SET UP
Battery Installation
1. This meter comes with a 9V battery.
2. Slide the rear cover down to expose the battery.
3. Gently pull out the 9V battery from the housing and
install the 9V battery, ensuring correct polarity.
4. Place the installed battery back into the housing, being
sure not to pinch the wires of the plug.
5. Replace the rear cover.
6. Repeat these steps when the low battery indicator
shows on the LCD screen.
Power On and O󰀨
1. Press the POWER button for less than one second to
turn the meter on in auto shut-o󰀨 mode.
This will be evident by the power icon in the upper
left corner of the screen. In this mode, the meter will
power o󰀨 after 5 minutes of inactivity.
2. To disable the auto power-o󰀨 feature, turn the meter
on by pressing the POWER button for more than 2
seconds and release. The meter will turn on and the
power icon will NOT be present.
3. To turn the meter o󰀨 at any time, press the POWER
button once.

ZERO CALIBRATION
1. Turn the meter on.
2. Place the lens cap on the sensor.
3. Press ZERO.
4. The screen will momentarily display “Adj” to indicate
your zero calibration was successful.
5. If the screen does not display “Adj”, the calibration was
not successful.
6. If the screen displays “CAP,” please ensure the lens
cap is tightly secured over the photosensor and try
again.
ACCESSING THE INTERNAL MEMORY
1. Turn the meter on.
2. Hold MEM until the lower left corner of the screen
displays “R”.
3. Use the UP and DOWN arrows to scroll through the
saved values. Note that the unit of measure stays with
the measurement.
4. Press MEM once to exit memory recall mode.
5. To clear the internal memory at any time, rst turn the
meter o󰀨. Then, while holding the MEM key, turn the
power on. “Clr” will display on the screen, indicating that
you have cleared the memory.

MEASUREMENT PROCEDURES
1. Turn the meter on.
2. Select your desired units by pressing LX/FC/CD to toggle
between Lux and Footcandles.**
**Note: If you want to activate the CD function, press
LX/FC/CD for more than 2 seconds to activate this mode,
explained on page 12.
3. Select your desired channel by pressing HOLD for more
than 2 seconds. The LS numerical value will blink at the
bottom of the screen.
4. Use the UP and DOWN arrows to change the L-value
to the desired channel. Use the Chart on the right as a
guide.
5. To conrm your channel selection, press HOLD for
more than 2 seconds again. The channel value will stop
blinking and the meter returns to regular measuring
mode.
6. Aim the photosensor at the light source. For best results,
hold the sensor as close to perpendicular as possible.
7. To freeze the reading on-screen, press HOLD. The value
will remain on the screen until you press HOLD again.
8. To view the MIN/MAX/AVERAGE over any interval, press
the UP arrow to scroll through the minimum, maximum,
and average values since the last time this feature was
activated. Press the UP arrow for more than 2 seconds to
exit this feature.
9. To store a reading in the meter’s internal memory, press
MEM. A numerical value will temporarily show in the
lower left side of the LCD screen, indicating successful
storage. You can also store an average value by pressing
MEM during a min/max/average measurement.

LUMINOUS INTENSITY
The luminous intensity feature of this meter allows you to
directly measure the intensity in Lux over distance. Please
note that this feature is based on a Lux measurement. The
formula for this calculation is as follows:
1. Luminous Intensity (CD) = (Illumination in Lux) x Distance
squared
2. Press POWER to turn the meter on.
3. Select your desired channel before switching to Luminous
Intensity mode (CD). You will not be able to change the
channel after CD begins.
4. Press LX/FC/CD for more than two seconds.
5. Use the UP and DOWN arrows to scroll to your desired
distance unit and press LX/FC/CD to conrm. You can
select meters or feet.
6. A number will blink in the lower right corner of the screen.
This is the distance to the light source. Use the UP and
DOWN arrows to set the distance to the source. You can
enter up to 30.4 meters or 99.9 feet.
7. Press LX/FC/CD to conrm. The meter will return to
measuring mode and you will be able to see the CD
result.
8. To exit CD mode at any time, press LX/FC/CD for more
than 2 seconds.
***NOTE: Do not enter the area between the meter and the
source. This is calculated for you based on the distance.
Enter only the linear distance from the source to the meter.

SPECTRAL SENSITIVITY
Like any device that relies on the translation of a photosensor
output to an electrical signal, there is an associated
bandwidth. Please see the diagram below to see the spectral
sensitivity of this LED light meter. The response is not the
same at every wavelength and it is important to note that
LED light covers many associated wavelengths.
-Relative Spectral Sensitivity
The deviation from the comparative standards for luminosity
is determined by JIS standard C 1609-1993.
Peak sensitivity wavelength: 550 nm
