Autool DM400 Multimeter
The Autool DM400 is a digital multimeter with automatic and manual range selection, designed for measuring electrical parameters such as voltage, current, resistance, capacitance, frequency, and temperature. The device features a large LCD screen with backlighting and a maximum display of 6000 counts, ensuring clear readings under various lighting conditions.
With True RMS technology, the DM400 provides accurate measurements even with non-sinusoidal signals. Additionally, the device is equipped with features such as data logging (MAX/MIN), automatic shutdown (with the option to disable this feature), and a low battery indicator. The robust housing and included accessories, including test leads and a TP01K thermocouple, make it a suitable choice for both professional use and DIY enthusiasts.
Functions:
- AC/DC voltage measurement: Measures AC voltage up to 750V and DC voltage up to 1000V.
- AC/DC current measurement: Measures AC and DC current up to 20A.
- Resistance measurement: Measures resistances up to 60MΩ.
- Capacitance measurement: Measures capacitances from 10pF to 6000μF.
- Frequency measurement: Measures frequencies from 1Hz to 10MHz.
- Duty cycle measurement: Measures duty cycles from 1% to 99%.
- Temperature measurement: Measures temperatures from -20°C to 1000°C with the included TP01K thermocouple.
- Diode and continuity test: Tests diodes and checks circuit continuity with an acoustic signal.
Special functions:
- True RMS measurements: For accurate results with complex signals.
- Automatic and manual range selection: For flexibility in various measurement conditions.
- Large LCD screen with backlight: For better readability under different lighting conditions.
- Data logging (MAX/MIN): For tracking measurement values.
- Automatic shutdown: To save battery, with the option to disable this function.
- Polarization indication and low battery indicator: For extra ease of use and safety.
- Protection up to 550V: In the resistance, capacitance, and frequency ranges.
