1) Precise and easy readout.
2) High accuracy in measuring.
3) LSI-circuit use provides high reliability and durability.
4) Permits a wide range of light measurements.
5) LOW BATTERY indicator.
6) Adjusting zero automatically and excellent operation.
7) LCD display provides low power consumption and clearly read out evening high ambient light.
8) Separate LIGHT SENSOR allows user take measurements at an optimum position.
3.Celsius and Fahrenheit temperature conversion
4.Range select button .Long press to exit RANGE state and enters the AUTO state
5.Short press can record data, press once time will record a data.
6.MAX and MIN selection button.
7.Back Light Button Switch
8.Press the “REL” key, the meter enters relative measuring mode, “REL” is displayed on the LCD and the present reading becomes the reference value and displayed on the display
9.Select FC units. When reading data state, Press the look down keys
10.The switch button, press the first boot, twice will shutdown.
11.Select the Lux units.
HOLD key: Press the “HOLD” key to lock display
12.value, and the “DH” sign will appear on the display, press it again to exit
1.Connect the battery, and then press the button to “ON”
2.Remove the photo detector cap and face it to light source in a horizontal position
3.Read the test value from the LCD display
4.Over range: if the instrument only display one “OL” in the LCD, the input signal is too strong, and a higher range should be selected
5.Data-Hold mode: press the HOLD key to select Hold model. When HOLD mode is selected, the LUX meter stops all further measurements and the test value with hold on the LCD. Press the button “HOLD” to the “ON”, the hold value will be cancelled
6.When the measurement is completed, replace the photo detector cap and turn the power selector OFF
7.When testing on strong light source(over 100k lux),the measure head need to close to light source slowly for measure .if can't test,move measure head away and test it again
1.It is necessary to replace another one 9V battery, when left corner of LCD display show“”
2.After turning off the meter, press the battery cover and push in the direction of the arrow to open
3.Disconnect the batter from the instrument and replace it with a standard 9-volt transistor battery and go for the cover.
