Features Overview
Let’s dive into the key features of the Uni T UT139C:
| Feature | Description |
|---|---|
| AC/DC Voltage Measurement | Measure both alternating and direct current voltages with precision. |
| AC/DC Current Measurement | Accurately measure both types of currents, up to 10A. |
| Resistance Measurement | Measure resistance values with a resolution of 0.1惟. |
| Continuity Test | Quickly identify open circuits and short circuits. |
| Diode Test | Test diode forward voltage and check diode functionality. |
| Capacitance Measurement | Measure capacitance values up to 200nF with a resolution of 1nF. |
Usage and Operation
Operating the Uni T UT139C is straightforward. Here’s a step-by-step guide to get you started:
- Power on the multimeter by pressing the power button located on the top right corner of the device.
- Use the selector switch to choose the desired measurement function. The switch is located on the left side of the display.
- Connect the test leads to the appropriate sockets. The red lead goes into the socket marked with a V (voltage) or mA (current), and the black lead goes into the COM (common) socket.
- For voltage and current measurements, connect the test leads across the circuit or component you want to measure.
- For resistance, continuity, diode, and capacitance measurements, touch the test leads to the component or circuit under test.
- Read the measurement value on the display.
