4. Instruccions de funcionament
4.1 Funcionament bàsic
- Encès/apagat: Rotate the central dial from the 'OFF' position to any desired function to turn the meter on. Rotate back to 'OFF' to power off.
- Selecció de la funció: Use the rotary dial to select the desired measurement function (e.g., V~ for AC Voltage, V- per a volúmenes de corrent continutage, Ω for Resistance).
- Terminals d'entrada: Connect the red test lead to the appropriate input jack (e.g., VΩHz for voltage/resistance, mAμA for small current, 20A for large current). Connect the black test lead to the 'COM' (common) jack.
4.2 Funcions de mesura
The ZT219 offers a wide range of measurement capabilities:
- DC/AC Voltage (V-, V~): Mesures voltage up to 1000V. Connect test leads in parallel with the circuit.
- DC/AC Current (A-, A~, mAμA): Measures current up to 20A. Connect test leads in series with the circuit. Ensure correct input jack selection (mAμA or 20A).
- Resistència (Ω): Measures resistance. Ensure the circuit is de-energized before measuring.
- Capacitance (CF): Measures capacitance up to 9.999mF. Ensure capacitors are discharged before testing.
- Freqüència (Hz) / Cicle de treball (%): Measures frequency up to 9.999MHz and duty cycle (1%-99%).
- Temperature (℃/℉): Measures temperature using the included K-type thermocouple probe (-20°C to 1000°C).
- Prova de díode: Comprova el volum de reenviamenttagcaiguda e d'un díode.
- Prova de continuïtat: Indicates continuity with an audible buzzer if resistance is below a certain threshold.
- Vol. Sense contactetage (NCV): Detecta la presència d'AC voltage without physical contact. Hold the NCV sensor near the conductor. The meter will indicate voltage with an audible beep and visual alert.
4.3 Característiques especials
- RMS veritable: Provides accurate measurements for non-sinusoidal AC waveforms.
- Classificació automàtica: Selecciona automàticament el rang de mesura adequat, simplificant el funcionament.
- Retenció de dades (HOLD): Freezes the current reading on the display. Press the 'HOLD' button to activate/deactivate.
- MAX/MIN Recording: Records the maximum and minimum values during a measurement session. Press 'MAXMIN' to cycle through MAX, MIN, and current readings.
- Il·luminació de fons: Illuminates the display for improved visibility in low-light conditions. Activated by pressing the 'HOLD/*' button.
- Apagat automàtic (APO): El mesurador s'apaga automàticament després d'un període d'inactivitat per estalviar bateria.
5. Manteniment
Proper maintenance ensures the longevity and accuracy of your ZOYI ZT219 Multimeter.
- Neteja: Netegeu el comptador amb anuncisamp drap i detergent suau. No utilitzeu abrasius ni dissolvents.
