1. Connect the black test lead to the "COM" jack and the red test lead to the "VΩmA" jack.
2. Set the function switch to the Continuity test position.
3. So àwọn ìwádìí ìdánwò pọ̀ mọ́ ara wọn ní gbogbo àyíká tàbí ẹ̀yà ara wọn.
4. If the resistance is less than approximately 70 ±30Ω, the built-in buzzer will sound, indicating continuity. The display will also show the resistance value.

5.7 Data Hold:

Press the "HOLD" button to freeze the current reading on the LCD display. Press it again to release the hold function and resume live readings.

6. Itọju

6.1 Iyipada Batiri:

When the low battery indicator appears on the display, replace the two LR44 batteries as described in Section 4.1. Using the meter with a low battery may result in inaccurate readings.

6.2 Fuse Replacement (10A Input):

The 10A input jack is protected by a fuse. If the meter does not read current on the 10A range, the fuse may be blown. To replace the fuse:

1. Rí i dájú pé a ti pa multimeter náà, kí o sì yọ gbogbo àwọn ìtọ́wò ìdánwò kúrò.
2. Ṣí ideri yàrá batiri náà gẹ́gẹ́ bí a ti ṣàlàyé rẹ̀ ní Apá 4.1.
3. Locate the fuse holder. Carefully remove the old fuse and replace it with a new fuse of the same type and rating (e.g., 10A/250V FUSED, as indicated on the meter).
4. Rọpo ideri batiri ki o ni aabo pẹlu dabaru.

6.3 Ninu:

Pa ọran naa pẹlu ipolowoamp cloth and mild detergent. Do not use abrasives or solvents. Periodically clean the input terminals with a cotton swab and alcohol to prevent poor contact from dirt or moisture.
