4-4 Battery Change The meter is powered by a 9V battery. When the symbol appears, the battery voltage drops below the level for reliable operation, the user has to replace a new battery. Turn the meter off first, open the battery cover on the back and replace the battery in the battery compartment.
5. Operation Instruction 5-1 Main Function Power ON/OFF Press and hold the Power button for 2 seconds to turn the meter on. Then all of symbols will appear for 2 seconds on the LCD. After power-on, the meter will measure and show the readings on the LCD continuously.

Example: Switch FL light source to INC light source. FL Light source Hold for 3 Secs. INC Light source Data Hold During measuring, press the HOLD button once to hold the measured values and the HOLD symbol will appear on the LCD. Press HOLD button again to return to measure.

Measuring Modes Color measurement and color difference are switchable by pressing MODE and button. Both of them also have 3 modes to select: ‧Color Measurement: 1. Ev, x, y (Illuminance, Color coordinate) 2. Ev, u', v' (Illuminance, Color coordinate, CIE1960) 3.

‧LCD Display in the Color Difference: 1. ⊿Ev, ⊿x, ⊿y(Color difference of Illuminance and Color coordinate) 2. ⊿Ev, ⊿u', ⊿v'(Color difference of Illuminance and Color coordinate, CIE1960) 3. ⊿Ev, ⊿CT(522), ⊿u'v'(Color difference of Illuminance and Color temperature)
5-2 SET Function Color Difference : This function allows user to set certain reference values ( Ev (522) ) to , u' , v' ref, compare with the target color. Set the Reference Value You can select one of these color difference modes to set: 1.
Page 20
Set the reference values in either of two methods: 5-2-1. Using the measured values and adjust it manually as the reference values. 5-2-2. Using the previous values stored in memory and adjusts it manually as the reference values. The difference between method 5-2-1 and 5-2-2 is whether the Data Hold was enabled before entering the set mode.(See diagram 5-2b)...
5-2-1 Using the Measured Values a.Select the(Ev, x, y)mode first and measure a light source. 1.Press the HOLD button to hold these values that you want to use as your reference values. 2.Press the button once to toggle the color difference mode.
