Description:
The MF-47E is a portable analog multimeter that uses a pointer display for measurements. Often used in school labs, electronics repair, and general home use, it can measure various electrical properties through a rotary knob. The “E” and “N” models often denote slight variations in function or scale, but they share the same fundamental purpose.
Functions and features:
The MF-47E is a multi-purpose tool for basic electrical work.
- Measurements: It can measure AC and DC voltage, DC current, and resistance. Some variants also include capacitance and battery testing.
- Continuity testing: Many models are equipped with a buzzer for easy continuity checks.
- Display: It features a classic pointer display with a clear, multiple-scale layout for reading measurements.
- Protection: It has built-in overload protection to prevent damage to the device.
- Design: The meter has a sturdy, desktop-style body and is powered by internal batteries.
