• V- (DC Voltage): Ikejjel il-volum tal-kurrent diretttage.
• Hz/% (Frequency/Duty Cycle): Measures frequency and duty cycle.
• Ω (Resistance): Ikejjel ir-reżistenza elettrika.
• Kontinwità/Dajowd: Checks for circuit continuity and tests diodes.
• NCV/Live: Mhux Kuntatt Voltage detection and Live Wire recognition.
• °C/°F (Temperature): Measures temperature using the included probe.
• hFE (Transistor Test): Measures transistor gain (requires optional socket).
• μA~ / μA- (AC/DC Microamperes): Measures microampere kurrenti.
• mA~ / mA- (AC/DC Milliamperes): Measures milliampere kurrenti.
• A~ / A- (AC/DC Amperes): Miżuri ampere current (up to 10A).

5.3 Funzjonijiet tal-buttuni

• SEL (Agħżel): Toggles between different functions within a single rotary switch position (e.g., AC/DC voltage, continuity/diode, °C/°F).
