How to use

To begin using the Uni-T UT383BT, insert the provided batteries into the compartment. Power on the device using the dedicated button. For standard measurements, point the light sensor directly toward the light source. Use the unit button to toggle between Lux and Foot-candles as required. To utilize the Bluetooth feature, download the iENV app on your mobile device, enable Bluetooth, and pair the meter to begin real-time data streaming. Use the HOLD button to freeze a reading on the screen or the MAX/MIN button to track the highest and lowest values during a session.

What to consider before purchase

• Ensure your mobile device is compatible with the iENV app for Bluetooth functionality.
• Verify that the measurement range meets the requirements of your specific application.
• Consider the need for a tripod, as the device includes a standard mounting socket for stable, long-term monitoring.

Usage recommendations

For the most accurate results, ensure the light sensor is clean and held at a consistent distance from the light source. Avoid casting shadows on the sensor during measurement. If performing long-term monitoring, utilize the tripod mount to maintain a fixed position and prevent manual interference.
