Power ON / OFF

Press the key  to power on the meter. To turn it off, just press this key  again. This meter is powered by x AAA dry cell batteries. To install or replace the batteries, just remove the battery cover and insert the new cells in the battery cartridge. Pay attention to the battery pole.


Lay the main unit into the holder with calibration standard of high gloss black tile. Take a reading by pressing the “MEAS” key. Compare the measured value with the value marked on the tile. If it matches the value on the tile holder, the instrument is within calibration and standard ready for use. If the measured value does not match the assigned value, just press the CAL key. It is necessary to inspect the condition of the calibration tile and instrument optics before each calibration. Any dust or debris on the optic should be blown from the lenses using dry clean air, the optics must not be touched. If there are any permanent marks or scratches on the lenses, the instrument is no longer suitable for measuring and should be returned to an authorized service center. The calibration tile must be perfectly clean from smears and scratches before attempting calibration. Fingerprints and dust can be removed with the supplied optic cleaning cloth.


Remove the holder and lay the Measurement Aperture just against the position that you want to measure. Take a measurement by pressing the “MEAS” key. The reading on the Display Screen within 2 seconds is the gloss value of that position. Meanwhile, the result is stored in memory automatically. When the instrument is placed on a sample the aperture is hidden, the center of the measurement area can be pinpointed by the intersection of the arrows marked on the front of the instrument case with those on the side.

Data Memorizing

When taking measurements, all values will be stored automatically in memory and the number of stored reading is accordingly increased by 1. The gloss meter can store up to 254 groups of data with measurement conditions. If the memory is full, the tester will auto save the new reading and discard the oldest one. That means the tester only holds the last 254 groups of data in memory.

Memory Recall

Under the measuring mode marked by ‘M’ on the display, press the  key to enter into the mode of viewing stored values marked by ‘R’. Press  key or  key to recall stored values forward and backward. To return to the measurement state, just press any key other than  or  key.

Delete Data in Memory

In the measurement state marked by ‘M’ on the display, the new reading can be deleted by pressing key “DEL”, and the number of stored reading is accordingly decreased by 1. To clear memory, just press and hold “DEL” key for 3 seconds till the number of stored reading becomes 000.

Download to PC

This meter can communicate with a PC by optional USB or RS232C cable and software. All the memorized data can download to your PC every time when in a measurement state marked by “MEAS” when you press  key to enter the viewing memorized state.

Auto Power Off

The instrument features an auto power off function designed to conserve battery life. If the tool is idle (neither measuring nor any key operation) for 10 minutes, it will turn itself off.

Battery Replacement

When the battery symbol appears on the display, it is time to replace the batteries. Slide the Battery Cover away from the instrument and remove the batteries. Install batteries paying careful attention to polarity.


  • The holder removed from the main unit should be kept in a safe and clean place to prevent from damage or pollution.
  • While measuring please keep environment light from directly irradiating into the measurement aperture.
  • If necessary, especially under strong light, shade it with a piece of light-tight cloth.
  • A big temperature difference between environment and meter would badly affect measuring accuracy. In such a case, please wait for a period of time till the temperature get to a balance and then calibrate the meter again.
  • If measurement operation lasts a long time, for example, an hour or more, it is necessary to recalibrate the meter.
