 6. Directions 

1.  Press the red POWER key to start the gauge, and "CAL?" is displaying in the screen, make the gauge measure-window pointing at the black quartz crystal standard board, press the yellow "OP"key to confirm adjustment operation, when "CAL OK" display the screen, the gauge adjustment finished, and then press yellow OP key to measure the black quartz crystal standard board, if the reading on the screen is correct, the adjustment is valid. 
2. After finishing adjustment operation, the gauge is entering into the measure state. Put the gauge on the measured sample, appoint the measure window to the measured object, press the yellow OP key, the gauge starts to measure, the luster value of the measured object will display on the screen while there is buzz sound, (2: ???----the luster value of 20°; 6: ???----the luster value of 60°;  8: ???----the luster value of 85°).please note that the measured object should be leveled off;
3. The gauge can be turned off with hand, press "POWER" key, it is in the close state, there is nothing displaying on the screen; if there is no measure operation in the gauge for 3 minutes, it will turn off automatically.
4. The measure state.press"OP"key 3 sec,display"clear ok",finish the clear operation

7. Matters required attention

1. It should avoid strong light direct radiation; or it will affect the measure precision. 
2.  The standard panel of the gauge should be kept clean, please do not touch the surface with fingues. If there is dirt on the surface, the measure precision will be affected. Wipe it with lens cloth or absolute alcohol. 
3. When the battery is running out, the gauge will display Battery low on the screen, which needs to change battery. Open the battery cover, replace the old battery with the new one, please pay attention to the joint line polarity. The battery should be changed when it runs up, otherwise, it stored for a long time may flow the liquid which cause damage of the instrument. It should be taken out and keep proper if it is not used for a long time.
