The Autool DM300 is a digital multimeter designed to perform a wide range of electrical measurements. The device features a True RMS measurement method for accurate results with both sinusoidal and non-sinusoidal AC signals. The multimeter has a display with 6000 counts and supports both automatic and manual range selection. Functions include measuring AC/DC voltage and current, resistance, capacitance, frequency, and temperature.
In addition to the standard measurement functions, the DM300 is equipped with various extra functionalities. The NCV (Non-Contact Voltage) function allows detection of alternating voltage without physical contact. Other functions include a Live Wire test, a continuity test with acoustic signal, a diode test, and a Data Hold function to retain measurement values. For safety, the multimeter is equipped with dual ceramic fuses and a robust silicone protective cover. A built-in LED flashlight illuminates the workspace in dark environments.
Application and functionality:
The Autool DM300 is suitable for diagnosis and maintenance of electrical systems in vehicles, industrial installations, and household applications. The main functionalities are:
- True RMS measurement: Provides accurate measurements for both sinusoidal and non-sinusoidal AC waveforms.
- NCV (non-contact voltage detection): Detects the presence of alternating voltage without physical contact, with visual and acoustic signals.
- Live wire test: Identifies the live wire in an AC circuit.
- Data hold function: Freezes the measured value on the display for easy reading.
- Automatic shutdown: Automatically turns off the device after a period of inactivity to save battery.
- Built-in LED flashlight: Illuminates the workspace for better visibility.
- Overload protection: Equipped with dual ceramic fuses to protect the device.
Measurement ranges and functions:
The instrument offers a wide range of measurement functions with the following ranges:
- AC/DC voltage: Measuring both direct and alternating voltage up to 1000V and 750V respectively.
- AC/DC current: Measuring direct and alternating current in the range of microamperes (μA) to 10A.
- Resistance: Resistance measurements from 600Ω to 60MΩ.
- Capacitance: Measuring capacitance from 6nF to 60mF.
- Frequency and duty cycle: Measuring frequency from 10Hz to 10MHz and the duty cycle.
- Temperature: Temperature measurements with the included thermocouple.
- Continuity and diode test: Testing the conductivity of circuits and the functionality of diodes.
