1. Digital Multimeter: Features auto-ranging and high accuracy, suitable for professional electricians. 2. AC Voltage Test: Supports AC voltage testing, with household voltage typically between 220V+15%. 3. Diode Test: The meter's diode output voltage is 3V, capable of lighting up LEDs and testing optocouplers. 4. Temperature Test: Supports temperature measurement using a K-type probe for ease of use. 5. DC Voltage Test: Can test 9V batteries; batteries below 9V may have reduced discharge capacity. 6. Diode Forward Voltage Drop & Resistor Test: Supports diode forward voltage drop testing and 1K color ring resistance testing, ideal for home use. 7. Continuity Test: The buzzer sounds and displays measured resistance when the circuit resistance is below 50. 8. Capacitance Test: Test capacitors by touching both ends with the red and black test leads. Discharge large capacitors before testing to prevent meter damage.
