2. Ọja Ipariview

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.

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. Tẹ awọn Agbara 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.

4.1 Gbigba Idiwon

To measure the light transmission of a sample:

  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 Data idaduro Išė

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.

4.4 RS232C Connectivity (Optional)

The WTM-1100 can be connected to a PC for data transfer and analysis using an optional RS232C cable and software (not included).

  • Locate the RS-232 port on the device.
  • Connect the RS232C cable (purchased separately) from the device to your PC.
  • Install the appropriate software on your PC to enable data communication.
