4. Nastavitev
4.1 Namestitev baterije
- Prepričajte se, da je merilnik IZKLOPLJEN.
- Poiščite pokrov predalčka za baterije na zadnji strani merilnika.
- Use a screwdriver to loosen the screw(s) and remove the cover.
- Vstavite novo 9V baterijo in pri tem upoštevajte pravilno polarnost (+ in -).
- Namestite pokrov predalčka za baterije in ga pritrdite z vijakom(-i).
4.2 Priključitev merilnih vodnikov
- Za voltage, resistance, and frequency measurements, insert the black test lead into the COM terminal.
- Rdeči testni kabel vstavite v VΩHz terminal.
- For specific 2-channel measurements or other functions requiring a second input, refer to the operating instructions for connecting to the CH2 terminal.
- Ensure connections are secure before proceeding with measurements.
5. Navodila za uporabo
5.1 Splošni postopek merjenja
- Turn the rotary dial to the desired measurement function.
- Priključite merilne kable ali clamp the jaws to the circuit under test as appropriate for the selected function.
- Read the measurement value(s) on the dual LCD display.
- If the reading is unstable or out of range, adjust the function or range if manual ranging is available.
5.2 Merjenje izmeničnega/enosmernega toka (Clamp)
Ta funkcija meri tok brez prekinitve tokokroga.
- Obrnite vrtljivi gumb na A~ (AC tok) ali A- (enosmerni tok).
- Odprite clamp čeljusti s pritiskom na sprožilec.
- Enclose only one conductor of the circuit within the jaws. Ensure the jaws are fully closed.
- Odčitajte trenutno vrednost na zaslonu. Pri enosmernem toku upoštevajte polarnost.
5.3 AC/DC Voltage Merjenje
- Priključite črni preskusni kabel na COM priključek in rdeči preskusni kabel do VΩHz terminal.
- Obrnite vrtljivi gumb na V~ (AC Voltage) ali V- (DC Voltage) položaj.
- Touch the test probes to the desired test points in the circuit.
- Preberite zvtage vrednost na zaslonu.
5.4 Resistance Measurement and Continuity Test
- Prepričajte se, da je preizkušani tokokrog brez napetosti.
- Priključite črni preskusni kabel na COM priključek in rdeči preskusni kabel do VΩHz terminal.
- Obrnite vrtljivi gumb na Ω (Odporni) položaj.
- Touch the test probes across the component or circuit section to be measured.
- For continuity, if the resistance is below a certain threshold (typically <50Ω), the meter will emit an audible beep.
