Instrument Operation :

1. SELF-TEST: Bring the main and auxiliary parts together, press the POWER button to power them, align the laser points with the bull’s eyes. Wait for SELF-TEST completion to enter the measurement interface.
2. Measurement: Clamp the sample with both parts, align the laser point with the bull’s eyes, and the meter will display the transmission (Rejection) value of the samples.

Features :

• Two-parts dual mode facilitates transmission measurement of automobile front windshield glass and building glass.
• Combines UV rejection, IR rejection, and light transmittance meter functions in one device.
• Built-in lithium rechargeable battery for easy use without battery replacement.
• Laser alignment function ensures accurate alignment for precise measurements.

FAQ :

• Q: What should I do if the SELF-TEST fails?
  A: If the SELF-TEST fails, please check if the battery power is low and charge both parts. Ensure proper alignment of laser points with the bull’s eyes. Do not power on with clamped testing samples or if there is equipment damage, send it back to the factory for repair.

 Button Operation

1. Power on/off
   Short press the “Power” button to power the instrument on/off, main and auxiliary part are required to perform the operation of power on/off. The meter is shut down automatically for no action within 15 minutes.

2. “HOLD” button of the main part
   Under the measurement mode, short press “HOLD” to hold the data on LCD, the icon “HOLD” will display on the LCD. Short press “HOLD” again to release the hold mode and the icon “HOLD” disappears.

3. “Laser” button of the auxiliary part
   Short press “Laser” button to power the laser on/off.

Instrument operation

1. SELF-TEST
   Attracting the main and auxiliary part together, press down “POWER” button to power them respectively and align the upper and lower laser points with the alignment bull’s eyes simultaneously. Wait for the completion of “SELF-TEST” and enter the measurement interface (VLT 100%, IRR and UVR 0% displayed on the LCD). The following reasons for failed “SELF-TEST” (“Please refer to the manual” display on the LCD):

   • Battery power is low, please charge the main and auxiliary part.
   • No alignment the main and auxiliary part with laser point with the bull’s eyes.
   • Power on the main and auxiliary part with clamped some testing sample.
   • Equipment damage, need to send back to the factory repair.

2. Measurement
   Clamp the sample with the main part and the auxiliary part and align the laser point with the bull’s eyes. The meter will display the transmission (Rejection) value of the samples.

Features

1. Two-parts dual mode of the main and auxiliary part facilitates the transmission measurement of the automobile front windshield glass and building glass.
2. UV rejection, IR rejection, light transmittance meter. Three function in ONE device.
3. The built-in lithium rechargeable battery is easy to use without replacing the battery.
4. The laser alignment function guarantees the accurate alignment of the main part with the auxiliary part in the process of measurement and ensures accurate measurement.

Battery charging

This meter has built in lithium chargeable battery and charger. Three methods can be used for charging the meter.

1. Plug the USB line into the USB port of computer. Plug in a one-for-two plug to charge the main and auxiliary part simultaneously.
2. Use the supporting DC 5V Adapter. Plug in a one-for-two plug to charge the main and auxiliary part simultaneously.
