Measuring procedure
1. Connect the photo sensor to the instrument, then turn on ON key, the display will show
numeral and unit “LUX”
2. Hold the sensor stationary during measuring and you can readout the value of Illumination.
3. Unit changeover by pressing the LUX/FC key to choose the required measuring unit in LUX
or F.C. (1 lux = 0.929 F.C.)
4. Auto range: The LX1010 is equipped with auto range function which is shown on the display.
5. “HOLD” function: if you want to keep the measurement date temporary, press HOLD key,
and press again to release this function.
6. When you finish measurement, press OFF key to turn off the power, meanwhile put the sensor
into the carrying case carefully to avoid scrape of white shield.
Signal output
•You can connect other accessories for applications such as recorder, controller, converter…
Signal output: DC 0-2V, 1mV/digit, impedance: 600 Ώ
Connector: Ǿ3.5 mono-phone plug.
•Extension cable: the length of low resistance signal cable should not exceed 100 meter for
application.
Display
FC : reading in Foot-candle (lm/ft2)
LUX : reading in LUX (lm/m2)
x10 : reading multiplied by 10
x100 : reading multiplied by 100
HOLD : data hold during measurement
: Low battery power warning
Safety precautions
•Keep the sensor clean and prevent scratch deformation of the sensor.
•Keep the instrument from high temperatures, high moisture and high static electricity
fields.
•Be sure to turn “OFF” the instrument when not using and take out the battery if the
•instrument will be used for a long time.
