7. Bakım
7.1. Temizlik
Multimetreyi temizlemek için kasayı bir bezle silin.amp Bez ve hafif deterjan kullanın. Aşındırıcı veya çözücü maddeler kullanmayın. Temizlemeden önce cihazın kapalı olduğundan ve herhangi bir elektrik devresinden bağlantısının kesildiğinden emin olun.
7.2. Pil Değişimi
When the low battery indicator appears on the display, replace the batteries as described in the 'Battery Installation' section (4.1). Always use new AAA batteries of the correct type.
8. Sorun Giderme
- Ekran/Güç sorunları yok: Pillerin doğru şekilde takılıp takılmadığını ve yeterli şarja sahip olup olmadığını kontrol edin. Gerekirse pilleri değiştirin.
- Yanlış okumalar: Ensure the correct measurement function is selected and test leads are properly connected. Verify that the component being tested is isolated from power if required.
- Devamlılık bip sesi yok: Check if the circuit is open or if the test leads are faulty.
- NCV şunları tespit etmiyor: Ensure the NCV probe is close enough to the AC voltage kaynak.
9. Kullanıcı İpuçları
- For capacitance measurements, especially with the FY106B model, ensure the capacitor is fully discharged before connecting the multimeter to avoid damage and ensure accurate readings. The FY106B is capable of measuring up to 40000μF.
- Utilize the 'HOLD' function when taking measurements in hard-to-reach areas to easily record the reading after removing the probes.
- The automatic mode is excellent for general checks, but for precise or specific tests, manually select the desired function.
