Description
This digital multimeter is designed for reliable and precise electrical measurements across multiple parameters, including DC and AC voltage, DC and AC current, resistance, frequency, capacitance, and inductance. It features high input impedance (up to 10MΩ) and built-in overload protection, allowing safe testing without damaging the instrument or circuits. Accuracy is specified as ±(…% of reading + …digits) at 23°C ±5°C and humidity below 80%, ensuring consistent performance in controlled environments.
The meter supports a wide variety of ranges, from millivolts to 1000 volts, microamps to 10 amps, ohms to tens of megaohms, Hz from 10Hz to 4000kHz, capacitance from 4nF to 40µF, and inductance from 4mH to 40H. Its versatile functionality and robust safety design make it suitable for engineering, laboratory testing, quality control, and field service applications, combining precision, reliability, and operational safety.
