5. Setup
5.1 Charging the Device
- Connect the provided Type-C cable to the device's Type-C interface.
- Connect the other end of the Type-C cable to a 5V 2A power adapter (not included) or a compatible USB port.
- The indicator light will show the charging status. A full charge typically provides 8,000 continuous tests.
5.2 Automatic Calibration
The device features automatic calibration for consistent accuracy.
- Ensure the device is placed correctly on the calibration base.
- Follow the on-screen prompts for automatic calibration. This typically involves a one-button start.
- Perform calibration regularly, especially after long periods of inactivity or if measurement accuracy is critical.
5.3 Using the Magnetic Base
The self-adhesive magnetic base provides a stable and convenient docking station for the colorimeter.
- Clean the desired desktop surface where you intend to place the base.
- Remove the protective film from the self-adhesive magnetic base.
- Firmly stick the base onto the cleaned surface.
- Place the colorimeter with its charging and calibrating base onto the magnetic base for secure storage and easy access.
6. Operation
6.1 Basic Color Measurement
- Ensure the device is charged and calibrated.
- Place the sample to be measured directly over the 6mm test aperture. Ensure full contact and no light leakage.
- Press the Test Button. The device will perform a measurement (approximately 1 second).
- The measurement results, including color values and color differences, will be displayed on the IPS touchscreen.
