UNI-T UT33B User Manual

The Model UT33B: the current measurement has 3 measurement positions
on the rotary switch: 200µA, 200mA and 10A.
The Model UT33C/UT33D: the current measurement has 4 measurement positions
on the rotary switch: 2000µA, 20mA, 200mA and 10A
To measure current, do the following:
1. Turn off power to the circuit. Discharge all high-voltage capacitors.
2. Insert the red test lead into the VΩmA or 10A terminal and the black test lead
into the COM terminal.
3. Set the rotary switch to an appropriate measurement position in A range.
4. Break the current path to be tested. Connect the red test lead to the more
positive side of the break and the black test lead to the more negative side
of the break.
5. Turn on power to the circuit.
The measured value shows on the display.
