4.2 Connexió dels cables de prova
Connecteu sempre els cables de prova correctament per a la mesura desitjada:
- Introduïu el cable de prova negre al COM Jack (comú).
- Per a la majoria de volumstage, resistance, continuity, diode, capacitance, and frequency measurements, insert the red test lead into the VΩHz jack.
- For current measurements up to 400mA, insert the red test lead into the mAµA jack.
- For high current measurements up to 10A, insert the red test lead into the 10A jack.
5. Instruccions de funcionament
5.1 Encès/Apagat
Rotate the function switch from the OFF position to any desired measurement function to turn the multimeter ON. To turn the multimeter OFF, rotate the function switch back to the OFF position.
5.2 Funcions de mesura
Select the desired measurement function by rotating the central rotary switch. Use the 'SELECT' button to toggle between AC/DC modes or different sub-functions within a range (e.g., Resistance, Diode, Continuity).
- Voltage Measurement (V~ / V-): Connect leads in parallel with the circuit.
- Current Measurement (A~ / A-): Connect leads in series with the circuit. Ensure correct jack (mAµA or 10A) is used.
- Resistance Measurement (Ω): Ensure circuit is de-energized before measuring.
- Capacitance Measurement (F): Ensure capacitor is discharged before measuring.
- Diode Test (→|): Used to check diode functionality and forward voltage gota.
- Continuity Test (•))): Emits an audible tone if resistance is below a certain threshold.
- Freqüència (Hz) / Cicle de treball (%): Measures the frequency and duty cycle of AC signals.
- Temperature Measurement (°C/°F): Use the included temperature probe.

5.3 Funcions especials
- GAMMA: Press to manually select a range instead of auto-ranging.
- RELΔ (Relative Measurement): Press to store the current reading as a reference for subsequent measurements.
- MÀXIM / MÍN: Press to display the maximum or minimum reading recorded during a measurement session.
- HOLD/* (Data Hold/Backlight): Press briefly to hold the current reading. Press and hold to toggle the backlight.
- NCV (vol sense contacte).tage): Detecta AC voltagi sense contacte directe.
6. Manteniment
6.1 Neteja
Netegeu el cas amb l'anunciamp cloth and mild detergent. Do not use abrasives or solvents. Keep the terminals free of dirt and moisture.
6.2 Substitució de la bateria
Refer to Section 4.1 for battery replacement instructions when the low battery indicator appears on the display.
6.3 Canvi de fusibles
If the current measurement function fails, the fuse may need replacement. This should only be performed by qualified personnel. Refer to the specifications for fuse type and rating.
6.4 Emmagatzematge
If the multimeter is not used for a long period, remove the batteries to prevent leakage and damage. Store the device in a cool, dry place, away from direct sunlight and extreme temperatures.
7. Solució De Problemes
If you encounter issues with your ANENG AN870 Multimeter, refer to the following common problems and solutions:
