User Guide / How to Use

Operating the UNI-T UT33A+ is straightforward. First, insert two 1.5V AAA batteries. To measure voltage, turn the rotary dial to the 'V' setting for AC or DC. Connect the black probe to the COM port and the red probe to the VΩmA port. Touch the probes to the circuit points to get a reading. For current measurements up to 10A, move the red probe to the 10A port and select the appropriate 'A' setting on the dial. For resistance or capacitance, select the Ω or F symbol respectively. The auto-ranging feature will automatically find the correct measurement scale for you.
