- Manuel tilstand: Press the 'SEL' button to cycle through different measurement functions (e.g., AC Voltage, DC Voltage, Resistance, Continuity, Capacitance, Frequency) when in a specific measurement category.

6.3. Specifikke målinger
6.3.1. bindtage-måling (AC/DC)
- Connect the red lead to 'VΩHz' and the black lead to 'COM'.
- Vælg AC eller DC voltage mode if not automatically recognized.
- Connect the test leads in parallel across the component or circuit to measure voltage.

6.3.2. Strømmåling (AC/DC)
- Connect the red lead to 'A' and the black lead to 'COM'.
- Vælg AC- eller DC-strømtilstand.
- Connect the multimeter in series with the circuit to measure current. Ensure the circuit is de-energized before connecting.

6.3.3. Modstandsmåling
- Connect the red lead to 'VΩHz' and the black lead to 'COM'.
- Vælg modstandstilstand.
- Connect the test leads across the component to measure its resistance. Ensure the component is isolated from the circuit and de-energized.
- The multimeter can also perform short-circuit detection, useful for appliance repair and checking motor coils or electrical appliances for leakage.

10. Brugertips
- Start High: Ved måling af en ukendt voltage or current, always start with the highest range setting to prevent overloading the meter. The FY106B's auto-ranging feature helps mitigate this, but manual mode users should be aware.
- Korrekt placering af ledning: Double-check that your test leads are in the correct input jacks for the measurement you intend to make (e.g., 'A' for current, 'VΩHz' for voltage/resistance).
- Batterikontrol: Regularly check the battery indicator. Low batteries can lead to inaccurate readings or unexpected shutdowns.
- Renhed: Keep the test leads and meter clean. Dirt or moisture can affect conductivity and safety.
