DM4070 Digital LCR Meter
The DM4070 Digital LCR Meter is a compact and reliable measuring instrument designed for testing passive electronic components such as resistors, capacitors, and inductors. It is an excellent choice for electronics technicians, engineers, students, and hobbyists who require accurate component measurements during repair, maintenance, or circuit development.
Equipped with a 3½-digit LCD display offering up to 1999 counts, the DM4070 measures resistance up to 20MΩ, inductance up to 20H, and capacitance up to 2000µF. Its manual ranging system provides precise measurements across multiple ranges, making it suitable for testing both small and large-value components.
One of its standout features is the built-in capacitor self-discharge function, which safely discharges stored voltage before measurement, helping protect both the instrument and the user. The meter also includes data hold, low battery indication, over-range indication, and automatic power-off to improve convenience and battery life.
Designed with a durable protective holster and an easy-to-read LCD screen, the DM4070 is well suited for electronics workshops, repair centers, educational laboratories, and field service applications. Whether you’re verifying component values before installation or diagnosing faulty circuits, this LCR meter delivers dependable and consistent results.
