3.2 Power On and Self-Calibration

After battery installation, the device will perform a self-calibration upon power-on. This ensures accuracy without manual adjustment.

  1. Apăsați tasta Putere buton pentru a porni instrumentul.
  2. The instrument will automatically self-calibrate. During this process, the display will show initial values and then settle to 100% VLT (or similar initial values depending on the model variant).
  3. Once self-calibration is complete, the device is ready for use.

4. Instrucțiuni de utilizare

4.1 Luarea unei măsurători

To measure the light transmission of a samppe:

  1. Ensure the device is powered on and has completed its self-calibration.
  2. Carefully insert the material (e.g., window, film) into the test slot between the transmitter and receiver probes.
  3. Ensure the two markings on the probe are properly aligned for accurate results.
  4. The measured Visible Light Transmission (VLT) percentage will be displayed instantly on the LCD.

4.2 Checking Calibration

To quickly verify the accuracy of the device's calibration:

  1. Use the included reference sample (test sheet) if available.
  2. Place the receiver probe on top of the test sheet.
  3. Compare the value shown on the LCD with the specified value on the test sheet. They should match closely.

4.3 Funcția de păstrare a datelor

The device features a data hold function to freeze the current reading on the display.

  • After taking a measurement, short press the DATA TRANS button (or equivalent data hold button) to lock the displayed value.
  • The "HOLD" indicator may appear on the screen.
  • To release the hold and return to live measurement, short press the button again.
