4. Setélan

4.1 Pamasangan batré

1. Ensure the multimeter is powered off.
2. Teang tempat panutup kompartemen batre dina tonggong alat.
3. Paké obeng pikeun muka kompartemen batré.
4. Insert two 1.5V AAA batteries, observing the correct polarity (+/-).
5. Ganti panutup kompartemen batré jeung amankeun ku screw nu.

4.2 Nyambungkeun Test Leads

1. Insert the black test lead into the 'COM' (Common) input jack.
2. Insert the red test lead into the 'INPUT' jack for most measurements (voltage, resistance, frequency, continuity).
3. Ensure the test leads are securely connected before taking any measurements.

5. Parentah Operasi

The FY128C Multimeter offers two primary measurement modes: Auto Identification and Manual Switching.

Figure 5.1: Two Measurement Modes

5.1 Daya Hurung/Pareuman

Pencét tombol kakuatan (U) to turn the multimeter on or off. The device features an auto-shutdown function to conserve battery power after a period of inactivity.

5.2 Auto Identification Mode

In this mode, the multimeter automatically identifies and measures AC/DC voltage, frequency, resistance, and continuity. Simply connect the test leads to the circuit or component, and the device will display the appropriate measurement.

5.3 Manual Switching Mode

For specific measurements or when auto-identification is not desired, you can manually switch between functions. Press the 'MODE' button (often indicated by a symbol like a wave or function icon) to cycle through AC/DC voltage, frequency, resistance, continuity, and NCV/LIVE functions.

5.4 AC/DC Voltage Pangukuran

1. Pilih vol anu cocogtage mode (AC V or DC V) if in manual mode, or rely on auto-identification.
2. Sambungkeun kabel tés sacara sajajar jeung sirkuit atawa komponén anu rék diukur.
3. Baca voltage nilai dina tampilan LCD.

5.5 Résistansi Ukur

1. Pastikeun sirkuit atanapi komponén parantos dipareuman énergina sateuacan ngukur résistansi.
2. Select the resistance mode (Ω) if in manual mode.
3. Sambungkeun kabel uji kana komponén.
4. Baca nilai lalawanan dina tampilan LCD.

5.6 Pangukuran Frékuénsi

1. Select the frequency mode (Hz) if in manual mode.
2. Connect the test leads to the circuit where you want to measure frequency.
3. Baca nilai frékuénsi dina tampilan LCD.

5.7 Tés Continuity

1. Pastikeun sirkuit atanapi komponén di-de-energized.
2. Select the continuity mode (often indicated by a buzzer icon).
3. Sambungkeun lead test kana komponén atawa kawat.
4. If there is continuity (a complete circuit), the multimeter will emit an audible beep.

5.8 Live Wire Checking

This function helps identify live wires without direct contact.

1. Select the 'LIVE' mode (often shared with NCV).
2. Bring the red test lead probe close to the wire or outlet.
3. The multimeter will indicate the presence of a live wire through visual (LED) and/or audible signals.

5.9 NCV (Vol. Non-Kontaktage) Tés

Fungsi NCV ngamungkinkeun deteksi voltase AC anu aman.tage without physical contact with the conductor.

1. Select the 'NCV' mode.
2. Bring the top part of the multimeter (NCV sensor area) close to the suspected voltage sumber.
3. The device will indicate the presence of AC voltage with an audible beep and/or visual indicator (e.g., LED lights). The intensity of the signal may vary with voltagkakuatan sareng jarak e.

5.10 Data Tahan Fungsi

Press the 'HOLD' button to freeze the current reading on the display. Press it again to release the hold and resume live measurements.

5.11 Flashlight and Backlight

Press the flashlight button (often indicated by a light bulb icon) to turn on the built-in flashlight. The LCD display also has a backlight for improved visibility in low-light conditions, which typically activates automatically or can be toggled with a dedicated button.

6. Pangropéa

6.1 beberesih

Lap multimeter casing jeung iklanamp cloth and mild detergent. Do not use abrasive cleaners or solvents. Ensure the device is completely dry before use.

6.2 Ngagantian batré

When the low battery indicator appears on the display, replace the batteries as described in Section 4.1. Always use fresh 1.5V AAA batteries.

6.3 Panyimpenan

If the multimeter will not be used for an extended period, remove the batteries to prevent leakage. Store the device in a cool, dry place, away from direct sunlight and extreme temperatures.
