İlk Güç Açık
Rotate the function selection knob from OFF to any measurement function to power on the meter. The LCD display will illuminate.
Kullanım Talimatları
Fonksiyon Seçimi
Rotate the central knob to select the desired measurement function. The meter features an automatic range for most measurements, simplifying operation.

Resim: Üzerindeview of the OWON CM2100's multiple measurement functions, including Resistance (Ω), NCV, VFC, HOLD, ON/OFF (continuity), LCD, Capacitance, Diode, Overload Protection, Low Battery Alert, Buzzing Prompt, and True RMS. It also highlights the 20000 counts, auto range, AC/DC voltage, and AC/DC current measurement capabilities.
Ölçüm Modları
- AC/DC Current Measurement (A~ / A=):
Rotate the knob to the 'A~' or 'A=' position. Press the trigger to open the clamp jaws and enclose a single conductor. Ensure the conductor is centered within the jaws for accurate readings. The display will show the current value. For DC current, press the DCA Reset button to zero the reading before measurement.
- AC/DC Hacmitage Measurement (V~ / V=):
Insert the red test lead into the VΩHz input jack and the black test lead into the COM jack. Rotate the knob to 'V~' for AC voltagDC voltaj için e veya 'V='tage. Connect the test leads in parallel to the circuit or component to be measured. The display will show the voltage değeri.
- Direnç Ölçümü (Ω):
Insert test leads as for voltage. Rotate the knob to the 'Ω' position. Connect the test leads across the component. The display will show the resistance value in Ohms (Ω).
- Kapasitans Ölçümü:
Insert test leads as for voltage. Rotate the knob to the 'Ω' position and use the Function Selector button to cycle to capacitance mode (usually indicated by 'nF', 'µF'). Connect the test leads across the capacitor. The display will show the capacitance value.
- Diyot Testi:
Insert test leads as for voltage. Rotate the knob to the 'Ω' position and use the Function Selector button to cycle to diode test mode (indicated by a diode symbol). Connect the red lead to the anode and the black lead to the cathode of the diode. The display will show the forward voltage damla.
- Süreklilik Testi:
Insert test leads as for voltage. Rotate the knob to the 'Ω' position and use the Function Selector button to cycle to continuity mode (indicated by a buzzer symbol). If the resistance is below a certain threshold, the buzzer will sound, indicating continuity.
- Temassız Hacimtage (NCV) Tespiti:
Rotate the knob to the 'NCV' position. Bring the NCV sensor (top part of the clamp meter) close to an AC voltage source. The NCV light will illuminate, and an audible beep will sound, with increasing frequency as the meter gets closer to the voltage kaynak.
- VFC (Variable Frequency Drive) Measurement:
Rotate the knob to the 'VFC' position. This mode is designed for measuring AC voltage and frequency of variable frequency drives, providing more stable readings in such environments.
- Frequency (Hz%) Measurement:
Rotate the knob to the 'Hz%' position. This mode measures the frequency of AC signals. Connect test leads as for voltage measurement. The display will show the frequency in Hertz (Hz).
Ek Fonksiyonlar
- HOLD Fonksiyonu: Press the HOLD button (often combined with backlight) to freeze the current reading on the display. Press again to release.
- Arka aydınlatma: Press and hold the HOLD/Backlight button to activate the display backlight for better visibility in low-light conditions. Press and hold again to turn off.
- Gerçek RMS: The CM2100 is a True RMS meter, meaning it accurately measures AC voltage and current for both sinusoidal and non-sinusoidal waveforms.
- Bluetooth Communication (CM2100B model only): If you have the CM2100B model, activate Bluetooth by pressing the BLE button. This allows remote data viewing and instrument control via a compatible smartphone application.
