4. Shutdown and Shutdown
Press and hold the "3-5 power button" to turn on the machine; the machine is powered by a 3.7 V lithium battery. When the instrument displays " 
", it means that the power is insufficient and needs to be charged; the general charging time is about four hours.
5. Instrument Calibration
Put the sensor in the calibration box, and then press the "3-2 MEAS measurement key", the instrument will display the reading . Compare the measured value with the value on the standard block. If the two match, the measurement status of the instrument is accurate . If the measured value does not match the actual value, you need to tap the instrument to automatically calibrate and display Same data . Before each calibration, check the glossiness of the calibration sheet and the sensor ; make sure the surface is clean and free of dirt such as oil and dust.
6. Angle selection
85° is low gloss, 60° is medium gloss, and 20° is high gloss; lightly press the "3-6 ANGLE" angle conversion key to realize the conversion of the measurement angle.
7. Instrumental Measurements
Move the measurement window of the sensor to the position , press down on the sensor lightly with your hand, so that the sensor and the object to be measured are in close contact, and then press the " 3-2 MEAS measurement key", the display will display There is his measured value; the value displayed on the LCD within 2 seconds is the luminosity of the measured position. At the same time the value will be saved .
8. Data memory
测量完成后，测量的数据将保存到仪器里，储存的测量数值也随测量相应增加。本仪器能够储存 254组测量值。当储存达到极限时仪器自动更新测量值，并删除优先的数值。也就是说仅是储存新的的 254组数据。
9. 数据查看
当显示器上出现“M”符号时说明机子属于测量状态，按住“3-4 RD 读取键”进入浏览状态，此时显示器出现“R”符号。这时按“3-4 RD 读取键或3-7CAL校准键”，“3-2 MEAS 测量键”就可以浏览到储存的所有数据。最后 则可退出此菜单。
10. 数据删除
测量状态时，即显示器出现“ M ”符号，按住“3-3 DEL 删除键”即可删除新的储存的数据，同时储存的数据也跟着递减。当要删除系统所有的数据时，只需按住“3-3 DEL 删除键”不松手并持续 3 秒钟，直到显示器所有数据显示为000，这时说明仪器无任何存储数据信息。
11. 与计算机联机通讯
本仪器可通过可选附件 RS232 通讯电缆、软件和 USB 适配器与计算机连接。用来分析、保存打印数据，通过蓝牙可远距离传输数据等多项功能操作。
12. 关机说明
该仪器具有两种关机功能，当仪器处于闲置状态（既不测量，也没有任何按键操作）10分钟后，它会自动关闭以节省电池。按住 显示“ OFF ”时松手就会关机。
* The instrument should be placed in a safe and clean place after use to prevent damage or contamination.
* Please keep the ambient light directly shining on the measuring aperture when measuring. Especially in strong light, it is necessary to use a cloth to shade.
* When the temperature difference between the measurement environments is large, it will seriously affect the measured value. In this case, wait the temperature to equilibrate before calibrating the meter.
* If the measurement operation continues for a long period of time, such as one hour or more, then recalibration of the instrument .
* When the instrument is not used for a long time, it is recommended to charge it once . "3-5 Power button"
