4.1 Agbara Tan / Pa
Turn the rotary dial from the OFF position to any measurement function to power on the multimeter. To power off, turn the dial back to the OFF position. The multimeter also features an automatic power-off function to conserve battery life.
4.2 Aṣayan iṣẹ
Rotate the central dial to select the desired measurement function (e.g., V~ for AC Voltage, V- fún DC Voltage, Ω for Resistance, A~ for AC Current, A- for DC Current, Temp for Temperature, etc.).
4.3 bọtini Awọn iṣẹ
- RANGE: Switches between automatic and manual ranging. In manual range, press repeatedly to cycle through available ranges.
- HOLD/☀: Press once to hold the current reading on the display. Press again to release. Long press to activate/deactivate the backlight.
- REL△: Relative measurement mode. Displays the difference between the current reading and a stored reference value.
- O pọju/MIN: Records and displays the maximum and minimum values measured during a session.
- Hz%: For frequency and duty cycle measurements.
- SEL/NCV: Selects between different sub-functions within a dial position (e.g., AC/DC, Diode/Continuity). Long press to activate Non-Contact Voltage (NCV) erin.
4.4 Performing Measurements
Always ensure the test leads are connected to the correct jacks and the function dial is set to the appropriate measurement type before connecting to a circuit.
- VoltagÌwọ̀n e (AC/DC): Select V~ for AC or V- for DC. Connect test leads in parallel with the circuit or component.
- Ìwọ̀n Lọ́wọ́lọ́wọ́ (AC/DC): Select A~ for AC or A- for DC. Connect test leads in series with the circuit. Ensure the correct current jack (mAµA or 10A) is used.
- Wiwọn Atako (Ω): Select Ω. Connect test leads across the component when it is de-energized.
- Iwọn Agbara: Select the capacitance function. Connect test leads across the capacitor when it is de-energized.
- Idanwo Diode: Select the diode function. Connect test leads across the diode.
- Idanwo Ilọsiwaju: Select the continuity function. Connect test leads across the circuit. A beep indicates continuity.
- Igbohunsafẹfẹ (Hz) / Iṣẹ́ iyipo (%): Select the Hz% function. Connect test leads to the signal source.
- Iwọn iwọn otutu: Connect the temperature probe to the appropriate jacks (usually VΩHz and COM). Select the temperature function.
- Non-Olubasọrọ Voltage (NCV): Long press the SEL/NCV button. Bring the top of the multimeter near an AC voltagorísun e. Mita naa yoo fihan wiwa voltage lai taara olubasọrọ.

Refer to Section 3.2 for battery replacement instructions. Replace batteries promptly when the low battery indicator appears on the display.
5.3 Fiusi Rirọpo
If the current measurement functions stop working, the fuse may need replacement. Fuses are located inside the multimeter. Fuse specifications are typically printed near the current input jacks (e.g., FUSED 10A MAX, FUSED 600mA MAX). To replace a fuse:
- Rí i dájú pé a ti pa multimeter náà, kí o sì yọ gbogbo àwọn ìtọ́wò ìdánwò kúrò.
- Open the back case of the multimeter (this may require removing screws).
- Carefully locate and remove the blown fuse.
- Replace it with a fuse of the exact same type and rating. Using an incorrect fuse can damage the meter or pose a safety hazard.
- Reassemble the multimeter, ensuring all screws are securely fastened.
