Familiarize yourself with the function dial and input terminals before proceeding with measurements.
6.1 Titan / Pa a
- To power on, rotate the central sliding switch from "OFF" to the desired measurement function (e.g., A~, V~, V=, Ω))).
- To power off, rotate the sliding switch back to the "OFF" position.
- The device features an automatic shut-off function to conserve battery life if left idle for a period.
6.2 Measuring AC Current (A~)
Lo clamp jaws to measure AC current without breaking the circuit.
- Rotate the sliding switch to the "A~" position.
- Ṣii clamp jaws by pressing the lever on the side.
- Fi adarí kan ṣoṣo ti Circuit naa sinu cl naaamp Ẹsẹ̀. Rí i dájú pé àwọn ẹ̀sẹ̀ náà ti sé pátápátá.
- Read the AC current value displayed on the LC screen.

- Insert the red test lead into the "V-Ω" input terminal.
- Rotate the sliding switch to the "V~" for AC voltage tàbí "V=" fún DC voltage.
- Connect the test leads in parallel across the circuit or component to be measured.
- Ka voltage value displayed on the LC screen.
6.4 Measuring Resistance (Ω) and Continuity Test ()))
Use the test leads for resistance and continuity measurements.
- Ensure the circuit or component is de-energized before measuring resistance or continuity.
- Fi okun idanwo dudu sinu ebute titẹ sii "COM".
- Insert the red test lead into the "V-Ω" input terminal.
- Rotate the sliding switch to the "Ω)))" position.
- For resistance: Connect the test leads across the component. Read the resistance value.
- For continuity: Connect the test leads across the circuit path. A continuous beep indicates continuity (low resistance).
6.5 Dimu Išė
The HOLD function allows you to freeze the current reading on the display.
- While a measurement is being taken, press the "HOLD" button. The displayed value will be frozen.
- Press the "HOLD" button again to release the reading and return to live measurement.
