Description: 1. Universal Multimeter: The UNI-T UT33D is a versatile multimeter designed for measuring various electrical parameters such as voltage, current, resistance, capacitance, frequency, and diode continuity. 2. Data Hold Function: This feature allows users to lock the displayed value on the screen for reference or recording purposes without affecting the measurement result. 3. Backlit LCD Display: The multimeter comes with a large, backlit LCD display that provides clear and easy-to-read measurements under various lighting conditions. 4. Relay Testing: The UNI-T UT33D features a dedicated relay testing function that allows users to test the normally open (NO) and normally closed (NC) contacts, coil resistance, and operating voltage of relays. 5. Auto Power Off: To save battery life, this multimeter has an automatic power off function that turns off the device after a set duration of inactivity. 6. CAT IV 600V Safety Rating: The UNI-T UT33D is safety rated for CAT IV 600V measurements
