2. Producte acabatview

The GAIN EXPRESS WTM-1100 is a portable digital window tint meter designed for accurately measuring the Visible Light Transmission (VLT) through various transparent or translucent materials, including automotive windows, filmed glass, and other samples. While the product title mentions capabilities for UV IR Rejection and Spectrum Testing, the primary measurement detailed in the specifications is Visible Light Transmission at 550 nanometers. It features a clear LCD display, one-key calibration, and a compact design for ease of use.

Característiques principals:

• Mesura precisa: Precisely measures Visible Light Transmission (VLT) from 0% to 100%.
• Aplicacions versàtils: Suitable for automotive, aerospace, glass products, plastic sheets, and more.
• Pantalla digital: Features a 10mm LCD display for clear reading results.
• Alta resolució: Provides accurate and reliable readings with high resolution.
• Disseny portàtil: Solid structure, small size, and lightweight for easy carrying and use.
• Mode de mesura contínua: Allows for ongoing measurements.
• Font de llum interna: Enables use in various lighting conditions, day or night.
• One-Key Calibration: Simplifies the calibration process for user convenience.
• Optional PC Connectivity: Can be connected to a PC via an optional RS232C cable and software (not included) for expanded functionality.

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. Premeu el botó Poder button to turn on the instrument.
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. Instruccions de funcionament

4.1 Prendre una mesura

To measure the light transmission of a sampLI:

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.

Figure 4.1: Proper probe alignment. This image illustrates how to align the two markings on the measuring probe to ensure accurate readings.

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 Funció de retenció de dades

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.
