Configuració

1. Instal·lació de la bateria

1. Localitzeu el compartiment de la bateria a la part posterior del multímetre.
2. Obriu la tapa de la bateria.
3. Insert two (2) AAA batteries, ensuring correct polarity as indicated inside the compartment.
4. Tanqueu la tapa de la bateria amb seguretat.

2. Connexió dels cables de prova

Insert the red test lead into the "VΩmA" input jack and the black test lead into the "COM" (common) input jack for most measurements. For high current measurements (10A), insert the red test lead into the "10A" input jack.

Instruccions de funcionament

Encès/Apagat

Premeu el botó Botó d'encesa to turn the multimeter on. The meter will automatically enter auto-ranging mode. To turn off, press and hold the Power button, or wait for the automatic shutdown after 15 minutes of inactivity.

Figure 4: The multimeter features an automatic shutdown after 15 minutes of inactivity.

Selecció de la funció

The SZ01 is an auto-ranging multimeter, simplifying most measurements. Use the Botó SEL to cycle through different measurement modes within a category (e.g., AC Voltage, DC Voltage, Resistance, Continuity, Frequency).

• VoltagMesura (CA/CC): Connect test leads in parallel to the circuit. The meter will automatically detect AC or DC voltage.
• Mesura de corrent (CA/CC): Connect test leads in series with the circuit. Ensure correct input jack (mA or 10A) is used.
• Mesura de la resistència: Assegureu-vos que el circuit estigui desenergitzat abans de mesurar la resistència.
• Prova de continuïtat: Use to check for open or closed circuits. A buzzer will sound for continuity.
• Mesura de freqüència: Measure the frequency of AC signals.

Funcions especials

• NCV (vol sense contacte).tage) Detecció:

  Manteniu premut el botó Botó NCV. Place the top of the multimeter near the cable or outlet. The meter will indicate the presence of AC voltage with beeps and an analog bar display.

• Live/Fire Wire Detection:

  Insert a single test lead (typically the red one) into the socket. The display will show "LIVE" and beep rapidly if it detects the live wire. If it's the neutral wire, there will be no beep or a different indication.

• Conservació de dades:

  Premeu el botó botó HOLD to freeze the current reading on the display. Press it again to release the hold.

Manteniment

• Neteja: Netegeu el comptador casing amb anunciamp cloth and mild detergent. Do not use abrasives or solvents. Ensure the meter is off and disconnected from all circuits before cleaning.
• Substitució de la bateria: Replace batteries promptly when the low battery indicator appears on the display to ensure accurate readings and proper operation. Refer to the "Battery Installation" section for instructions.
• Emmagatzematge: If the meter is not used for a long period, remove the batteries to prevent leakage. Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures.
• Cables de prova: Regularly inspect test leads for any signs of damage, such as cracked insulation or exposed wires. Replace damaged leads immediately.
