4.2. Uji Sambungan Utama

Connect the test leads to the appropriate input jacks before taking any measurements.

• Sambungkan hitam ujian membawa kepada COM bicu input (biasa).
• Untuk kebanyakan ukuran (voltage, resistance, frequency, duty cycle, continuity), connect the merah ujian membawa kepada VΩHz bicu input.
• For current measurements (mA), connect the merah ujian membawa kepada mA bicu input.
• For higher current measurements (A), connect the merah ujian membawa kepada A input jack (if available and distinct from mA). Note: The PM8213C typically uses a single current input for mA/A, check the dial for specific ranges.

5. Arahan Operasi

5.1. Hidupkan/Mati Kuasa

To turn the multimeter ON, rotate the function switch from the OFF position to any desired measurement function. To turn the multimeter OFF, rotate the function switch to the OFF position. The meter features an automatic power-off function after approximately 30 minutes of inactivity to conserve battery life.

5.2. Pemilihan Fungsi

Use the rotary switch to select the primary measurement function. For functions with multiple modes (e.g., AC/DC voltage, continuity/diode), press the SEL button to toggle between modes.

5.3. Mengukur DC Voltage (V-)

1. Connect the red test lead to the VΩHz jack and the black test lead to the COM jack.
2. Set the rotary switch to the V- position.
3. Connect the test leads in parallel to the DC voltage source or component you wish to measure.
4. Baca voltagnilai e pada paparan LCD.

5.4. Mengukur Vol ACtage (V~)

1. Connect the red test lead to the VΩHz jack and the black test lead to the COM jack.
2. Tetapkan suis putar kepada kedudukan V~.
3. Connect the test leads in parallel to the AC voltage sumber atau komponen.
4. Baca voltagnilai e pada paparan LCD.

5.5. Mengukur Rintangan (Ω)

1. Pastikan litar dinyahtenagakan sebelum mengukur rintangan.
2. Connect the red test lead to the VΩHz jack and the black test lead to the COM jack.
3. Set the rotary switch to the Ω position.
4. Sambungkan petunjuk ujian merentasi komponen yang rintangannya ingin anda ukur.
