Measurement Principle and Introduction

This product conforms to the international standard ISO 2813 and the Chinese national standard GB/T9754, and acts the requirements of JJG696 working gloss meter. Under  normal use conditions, Non-contact gloss meter is the same as our company’s gloss meter. With automatic calibration, it has four measurement modes: basic mode, quality control  mode, statistical mode and continuous mode to meet different measurement needs. At the same time, it has quality management software.
The special design of Non-contact gloss meter enables the instrument to carry out contact measurement and non-contact measurement with an interval of 10mm. As shown in the  figure below, the distance between the calibration plate and the sample to be tested should be 10mm from the Non-contact gloss meter gloss basic plate. When the instrument 1s  connected to a 10mm calibration bracket (refer to Figure 1), the sample to be tested can be attached to the calibration bracket to achieve contact measurement. When the instrument is not connected to the 10mm calibration bracket (refer to Figure 1), the measured sample is 10mm away from the bottom of the instrument to achieve non-contact measurement.
There are two sampling procedures for Non-contact gloss meter. One is, 1n the normal measurement mode, that the lighting source is turned on, the sample to be tested is  illuminated, the detector signal is collected, the lighting source is turned off, and the glossiness of the sample to be tested is output. The single measurement time is 1 second; the other is that when the online measurement mode is turned on, the lighting source will be turned on all the time, and the detector will collect and output signals uninterruptedly, so that the  measurement period can be as short as possible, and the single measurement period is 180 milliseconds.

Switch on/off

Startup

The instrument is powered by an external power adapter through the USB interface (dry batteries can also be used in special cases). When using battery power, press the  measurement button to turn on; if using USB power, it will automatically turn on when the USB is plugged in and connected to the power supply.
If the calibration plate is detected during startup, the instrument will be calibrated automatically.
If the calibration 1s passed, the interface shown in Figure 2 will be displayed, and at this time, press the measurement button to enter the measurement interface.

If the calibration is failure, it is as shown in Figure 3.

After the calibration is failure, please choose to press the measurement button to retry or press the return button to directly enter the measurement interfacc. If you try again, please  check these first:

1. Whether the calibration plate 1s in good connection or not;
2. Is the calibration tile clean?
3. Calibration tile protection paper is removed.

Shutdown

When using battery power, the instrument will automatically shut down within a certain period of time (30 seconds by default, which can be changed in the settings).
It can also be turned off by pressing and holding the measurement button for more than 3 seconds.
It is not able to turn off when using USB power.
