Overview Mini ColorReader is a portable small color measuring instrument with small size, convenient use and accurate measurement. It is widely used in industries such as plastic electronics, paint and coating, textile and garment printing and dyeing. The instrument can be connected to the mobile phone APP and SQCX PC quality management software to achieve more functional expansion. The mobile APP comes with multiple sets of electronic color cards, which can realize color card retrieval and matching. The mobile phone APP and SQCX PC software have a variety of light source, color space, color index, and reflectance functions, which can realize massive chromaticity index testing. This instrument has the following advantages: 1) It can be measured after power-on, no need to perform white calibration every time, making color measurement easier; 2) Separate design of calibration whiteboard and measuring port to ensure long service life of whiteboard and accurate measurement; 3) Accurate, stable, small size, easy to carry, APP built-in mobile electronic color card, it is a good helper for mobile color quality control; 4) A variety of chromaticity parameters can be set on the instrument side, test records can be checked, and the stand-alone function is powerful; 5) Built-in rechargeable lithium battery, Type-C USB interface, easy to use; 6) Connect the mobile phone APP and PC SQCX software to achieve more functional expansion. 1.

Operating instructions 2.1 Battery instructions This instrument uses a built-in lithium battery, the specification of the lithium battery is Li-ion 3.7V, and the capacity is 800mAh. Use a USB data cable to connect to the USB port on the PC or connect to a 5V==1A power adapter to charge the lithium battery. The maximum charging current can reach 500MA. When charging, the battery level is greater than 80%, the LED indicator is green, the battery level is less than 20%, the LED indicator is red, and the battery level is between 20% and 80% is yellow. The display shows a charging prompt, and the charging is complete, indicating that the battery is full. 2.2 Switch on and off Power on: In the power off state, press the power switch, the instrument is powered on, the LED indicator flashes, the display screen lights up and enters the measurement interface. Shutdown: In the power-on state, long press the power switch to shut down the instrument. When the automatic sleep mode is turned on, the instrument will automatically shut down. Note: When not using the instrument for a long time, please turn off the power. 2.3 Black and white calibration In the measurement interface, long press the "operation button" to enter the system function interface, slide the "operation button" to the left or right, position the cursor on the "black and white calibration", and long press the "operation button" to enter the calibration interface. The instrument has built-in calibration parameters, and calibration is needed when the environment changes drastically. Black calibration: "black calibration" the instrument against the air, the surrounding must be a darker environment without bright light sourc…
