4.1 Fifi sori batiri

The MAS830L multimeter is powered by one 9V 6F22 battery. To install or replace the battery:

1. Rí i dájú pé a ti pa multimeter náà, kí o sì yọ gbogbo àwọn ìtọ́wò ìdánwò kúrò.
2. Wa awọn yara batiri lori pada ti awọn kuro.
3. Unscrew the retaining screw(s) and remove the battery cover.
4. Insert the 9V battery, observing the correct polarity (+ and -).
5. Rọpo ideri batiri naa ki o si fi skru(s) so o mọ.

Àmì batiri tí kò tó nǹkan yóò hàn lórí ìbòjú nígbà tí batiri náà bá nílò àyípadà.

4.2 Nsopọ Awọn itọsọna Igbeyewo

Connect the red test lead to the "VΩmA" input jack and the black test lead to the "COM" input jack for most measurements. For high current measurements (up to 10A), connect the red test lead to the "10A" input jack.

5. Awọn ilana Iṣiṣẹ

Before taking any measurement, ensure the rotary switch is set to the correct function and range.

5.1 DC Voltage Measurement (V—)

1. Ṣeto iyipada iyipo si DC Vol ti o fẹtagibi tí a lè fi pamọ́ sí (fún àpẹẹrẹ, 200mV, 2V, 20V, 200V, 600V).
2. So okun idanwo pupa naa pọ mọ apa rere (+) ti iyipo naa ati okun idanwo dudu naa pọ mọ apa odi (-).
3. Ka voltage iye lori ifihan.

5.2 AC VoltagÌwọ̀n e (V∼)

1. Ṣeto iyipada iyipo si AC Vol ti o fẹtagibi tí a lè lo agbára iná (fún àpẹẹrẹ, 200V, 600V).
2. So awọn itọsọna idanwo kọja AC voltage orisun.
3. Ka voltage iye lori ifihan.

5.3 DC Current Measurement (A—)

1. Set the rotary switch to the desired DC Current range (e.g., 2mA, 20mA, 200mA, 10A).
2. For measurements up to 200mA, connect the red lead to "VΩmA". For 10A, connect the red lead to "10A".
3. Fọ́ àyíká náà kí o sì so multimeter pọ̀ ní ìtẹ̀léra pẹ̀lú ẹrù náà.
4. Ka iye lọwọlọwọ lori ifihan naa.

5.4 Ìwọ̀n Àìfaradà (Ω)

1. Rii daju pe iyika naa ti ni agbara ṣaaju idiwọn resistance.
2. Set the rotary switch to the desired Resistance range (e.g., 200Ω, 2kΩ, 20kΩ, 200kΩ, 2MΩ).
3. So awọn itọsọna idanwo kọja paati lati ṣe iwọn.
4. Ka iye resistance lori ifihan.

5.5 Diode Test (→|→)

1. Ṣeto iyipada iyipo si ipo Idanwo Diode.
2. So asiwaju igbeyewo pupa pọ si anode ati asiwaju idanwo dudu si cathode ti diode.
3. Awọn àpapọ yoo fi awọn siwaju voltage drop. Yi awọn itọsọna pada lati ṣayẹwo fun awọn iyipo ṣiṣi (OL).

5.6 Continuity Test (♥)

1. Ṣeto iyipada iyipo si ipo Idanwo Itẹsiwaju.
2. So awọn itọsọna idanwo kọja Circuit tabi paati.
3. If the resistance is less than 70 ±30Ω, the built-in buzzer will sound, indicating continuity.

5.7 Data Hold Function (HOLD)

Tẹ bọtini "DÍDÁ" lati di kika lọwọlọwọ lori ifihan naa. Tẹ ẹ lẹẹkansi lati tu idaduro naa silẹ ki o si tun bẹrẹ awọn kika laaye.

6.2 Batiri Rirọpo

Refer to Section 4.1 for battery installation and replacement instructions. Replace the battery promptly when the low battery indicator appears to ensure accurate readings.

6.3 Fiusi Rirọpo

The multimeter is protected by internal fuses. If the current measurement function stops working, the fuse may need replacement. This procedure should only be performed by qualified personnel. Use only fuses of the specified type and rating (e.g., MAX 200mA/250V FUSED, MAX 10A/250V FUSED).
