Extech Ex350: Full Specifications, Comparisons, Manuals, Pros And Cons, Problems, And Where To Buy

Extech EX350 Information

The EX350 also features a built-in non-contact voltage detector (NCV), which allows you to safely check for the presence of AC voltage without making contact with the circuit. This is a useful safety feature, especially when working with high-voltage circuits.

In addition to its basic measurement functions, the EX350 also offers a number of advanced features, including:

Low Impedance (LoZ) mode: This mode eliminates false readings caused by ghost voltages, which are small AC voltages that can be picked up by the multimeter even when there is no real AC voltage present.
Low Pass Filter (LPF): This filter attenuates high frequencies, which can help to reduce noise and improve the accuracy of your measurements.
Variable Frequency voltage measurements: This feature allows you to measure the frequency of AC voltage signals.
Data Hold: This feature allows you to freeze the displayed measurement so that you can read it more easily.
Min-Max: This feature records the minimum and maximum values of a measurement, which can be useful for troubleshooting problems.
Relative mode: This mode allows you to measure the difference between two voltages or currents.
Capacitance zero: This feature allows you to measure the capacitance of a capacitor by setting the multimeter to zero before making the measurement.
Auto power off: This feature automatically turns off the multimeter after a period of inactivity, which helps to conserve battery life.

The Extech EX350 is a well-made and versatile multimeter that offers a wide range of features and functions. It is a good choice for professionals who need a reliable and accurate multimeter for a variety of applications.
