Saugos informacija
ĮSPĖJIMAS: Kad išvengtumėte elektros smūgio ar sužalojimų, prieš naudodami šį gaminį, perskaitykite ir supraskite visą saugos informaciją.
- Visada laikykitės vietinių ir nacionalinių saugos taisyklių.
- Nenaudokite matuoklio, jei jis atrodo pažeistas arba jei izoliacija yra pažeista.
- Netepkite daugiau nei vardinis tūristage, kaip pažymėta ant skaitiklio, tarp gnybtų arba tarp bet kurio gnybto ir įžeminimo.
- Būkite atsargūs dirbdami su voltagesant didesnei nei 30 V AC RMS, 42 V pikinei vertei arba 60 V DC įtampai. Šie įtampų lygiaitagtai kelia šoko pavojų.
- Prieš atidarydami baterijų dangtelį, atjunkite bandymo laidus nuo matuoklio.
- Įsitikinkite, kad funkcijų jungiklis yra teisingoje padėtyje, kad būtų atliekamas matavimas.
- Nenaudokite matuoklio šalia sprogių dujų, garų ar dulkių.
- Always use appropriate personal protective equipment (PPE).

Pradinis įjungimas
Rotate the function selection knob from OFF to any measurement function to power on the meter. The LCD display will illuminate.
Naudojimo instrukcijos
Funkcijos pasirinkimas
Rotate the central knob to select the desired measurement function. The meter features an automatic range for most measurements, simplifying operation.

Vaizdas: Baigėsiview 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.
Matavimo režimai
- 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 ttage 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 voltage arba „V=“, jei tai nuolatinės srovės tūristage. Connect the test leads in parallel to the circuit or component to be measured. The display will show the voltage vertė.
- Varžos matavimas (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).
- Talpos matavimas:
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.
- Diodo testas:
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 lašas.
- Tęstinumo testas:
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.
- Nekontaktinis ttage (NCV) aptikimas:
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 šaltinis.
- 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).
Papildomos funkcijos
- LAIKYMO funkcija: Press the HOLD button (often combined with backlight) to freeze the current reading on the display. Press again to release.
- Foninis apšvietimas: 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.
- Tikrasis 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.
