It is ideal for measuring the current flowing through conductors without disconnecting or cutting the wire. The current measuring range typically covers from a few milliamps (mA) up to several hundred amps (A). 3-3/4 Digit Display: The meter features a 3-3/4 digit LCD display, providing clear readings with a maximum display of 3999 counts. The display is designed for easy visibility and accurate reading, even in dimly lit environments. Voltage Measurement: It can measure both AC and DC voltage. This allows you to test the voltage in electrical systems, outlets, and batteries. The voltage range typically spans from low voltages (mV) up to several hundred volts (V). Resistance Measurement: The MT-3202 can measure resistance in the circuit, helping you diagnose issues like open circuits, shorts, or faulty components. It has a wide resistance range, usually from a few ohms up to megaohms (MΩ). Continuity Test: The continuity test function is available, which helps in checking if a circuit or wire is complete or if there’s a breakage in the line. The meter emits an audible beep if continuity is present, allowing for a quick assessment. Clamp Function: The clamp function allows you to measure current without the need to disconnect the circuit. Simply clamp around the conductor, and the meter will measure the current flowing through it. The clamp jaw size is designed to fit around most standard-sized cables, providing accurate readings in tight or difficult-to-reach places. True RMS Measurement: The meter is equipped with True RMS (Root Mean Square) measurement capability, which ensures accurate readings for non-sinusoidal or distorted waveforms, commonly found in modern electronic devices and industrial applications. Data Hold Function: The Data Hold feature allows you to freeze the current reading on the display for easy reference. This is particularly useful when measurements need to be recorded or examined in more detail. Backlight Display: The meter includes a backlit LCD display, which ensures visibility in low-light conditions, such as when working in dimly lit panels or control boxes. Auto Range: The device features auto-ranging, which automatically selects the appropriate range for the measurement being taken, eliminating the need for manual adjustments. Safety Features: The Proskit MT-3202 is designed with safety in mind, adhering to international safety standards such as CAT III 600V. This ensures that the meter can handle high voltages safely during operation. Built-In Data Storage: Some versions of the meter may include a data storage function for recording readings, which is beneficial for long-term monitoring or documentation purposes. Battery-Powered: Powered by a standard battery, the MT-3202 is portable and does not require external power sources, making it suitable for fieldwork and remote locations. Applications: Electrical Maintenance: Ideal for electricians and maintenance personnel to measure and troubleshoot electrical systems in both residential and industrial settings.
