4. Impostazione

4.1 Battery Installation (Both Devices)

Both the Multimeter HT118A and Brake Fluid Tester KVBF01 require 2x1.5V AAA batteries.

1. Individuare il coperchio del vano batteria sul retro del dispositivo.
2. Utilizzare un cacciavite (se necessario) per aprire il coperchio.
3. Inserire 2 batterie AAA, rispettando la polarità corretta (+/-).
4. Riposizionare il coperchio del vano batteria e fissarlo.

Note: Ensure batteries are installed correctly to prevent damage to the device.

5. Istruzioni per l'uso

5.1 Funzionamento del multimetro digitale KAIWEETS HT118A

The HT118A features auto-ranging for most functions, simplifying operation. Connect the test leads to the appropriate input jacks (COM and VΩmA for most measurements, 10A for high current).

Funzioni di misurazione:

• Volume AC/DCtage(V): Turn the dial to V~ (AC) or V- (DC). The multimeter will auto-range.
• AC/DC Current (A, mA): Turn the dial to A~ (AC) or A- (DC) for high current, or mA~ (AC) or mA- (DC) for low current. Ensure test leads are connected to the correct current input jack (10A or mA).
• Resistenza (Ω): Turn the dial to Ω.
• Continuity (•))): Turn the dial to •))). A buzzer will sound for low resistance.
• Diode (→|): Turn the dial to →|.
• Capacitance (∔): Turn the dial to ∔.
• Frequenza (Hz): Can be measured in conjunction with voltage or current functions, or as a standalone function.
• Temperatura (°C/°F): Turn the dial to °C/°F. Connect the K-type thermocouple to the VΩmA and COM jacks.

• NCV (Volume senza contattotage): Turn the dial to NCV. Bring the top of the multimeter near an AC voltage fonte per rilevarne la presenza senza contatto diretto.
• Rilevamento di cavi sotto tensione: Turn the dial to Live. Insert the red test lead into the VΩmA jack and touch the probe to the wire. The display will indicate if it's a live wire.

Funzioni dei pulsanti:

• FUNZIONE: Toggles between different sub-functions within a dial setting (e.g., AC/DC, Diode/Continuity).
• TENERE: Blocca la lettura corrente sul display. Premere di nuovo per rilasciare.
• MASSIMO/MIN: Displays the maximum or minimum reading recorded during a measurement session.
• Retroilluminazione/Torcia: Activates the display backlight and/or the built-in flashlight.
