4.1 Pemasangan Bateri

The Mastech MS2015B is powered by a 9V battery. To install or replace the battery:

1. Pastikan meter dimatikan dan semua kabel ujian diputuskan sambungannya.
2. Cari penutup petak bateri di belakang meter.
3. Tanggalkan skru penahan dan tanggalkan penutup.
4. Connect a new 9V battery to the battery connector, observing correct polarity.
5. Letakkan bateri ke dalam petak dan gantikan penutup, selamatkannya dengan skru.

Note: The meter features a low battery alarm function. Replace the battery promptly when this indicator appears to ensure accurate measurements.

5. Arahan Operasi

Before taking any measurements, ensure the meter is in good working condition and the correct function is selected.

5.1 Pengukuran Arus AC (Clamp)

1. Turn the rotary switch to the "A~" position.
2. Tekan clamp jaw trigger to open the jaw.
3. Enclose a single conductor (not a cable containing multiple conductors) with the clamp Rahang.
4. Lepaskan picu untuk menutup rahang dengan selamat di sekeliling konduktor.
5. Read the AC current value on the display. The sub-LCD display may show the frequency.

5.2 AC/DC Jldtage Pengukuran

1. Insert the black test lead into the "COM" jack and the red test lead into the "INPUT" jack.
2. Turn the rotary switch to the "V~" position for AC voltage atau "V=" untuk DC voltage (use FUNC button to toggle if combined).
3. Sambungkan kuar ujian secara selari dengan litar atau komponen yang diuji.
4. Baca voltagnilai e pada paparan.

5.3 Pengukuran Rintangan

1. Insert the black test lead into "COM" and the red test lead into "INPUT".
2. Putar suis putar ke kedudukan "Ω".
3. Pastikan litar atau komponen dinyahtenagakan sebelum mengukur rintangan.
4. Sambungkan kuar ujian merentasi komponen.
5. Baca nilai rintangan pada paparan.

5.4 Pengukuran Kapasitansi

1. Insert the black test lead into "COM" and the red test lead into "INPUT".
2. Turn the rotary switch to the "Ω" position and press FUNC until the capacitance symbol (nF, µF) appears.
3. Ensure the capacitor is fully discharged before measurement to avoid damage to the meter.
4. Sambungkan kuar ujian merentasi terminal kapasitor.
5. Baca nilai kapasitans pada paparan.

5.5 Pengukuran Kekerapan

Frequency can be measured in conjunction with AC current or AC voltage.

• When measuring AC current (A~) or AC voltage (V~), the sub-LCD display will automatically show the frequency (Hz).

5.6 Bukan Kenalan Voltage (NCV) Pengesanan

1. Putar suis putar ke kedudukan "NCV".
2. Move the top of the clamp jaw near a live AC voltage sumber.
3. The meter will indicate the presence of AC voltage through an audible beep and/or visual indicator on the display.

5.7 Pengukuran Suhu

1. Insert the temperature probe into the "COM" and "INPUT" jacks, observing polarity.
2. Turn the rotary switch to the "Temp" position.
3. Letakkan hujung probe suhu pada atau berhampiran objek yang suhunya hendak diukur.
4. Baca nilai suhu pada paparan.

5.8 Menggunakan Butang Fungsi

• FUNGSI: Toggles between measurement modes (e.g., AC/DC, Resistance/Continuity/Diode, Capacitance).
• Lampu latar/lampu suluh: Press briefly for backlight, press and hold for flashlight.
• RANGE: Press to switch between auto-ranging and manual ranging. In manual range, press repeatedly to cycle through ranges.
• MAKS MIN: Press to enter MAX/MIN recording mode. The meter will display the maximum or minimum value measured since activation. Press again to cycle.
• REL: Press to store the current reading as a reference value. Subsequent measurements will be displayed as the difference from this reference.
• DIBERI: Tekan untuk membekukan bacaan semasa pada paparan. Tekan sekali lagi untuk melepaskan.
