Fluke 373 Pros/Cons and My Thought

The Fluke 373 is a digital multimeter (DMM) that is popular among electricians and other professionals who need to measure electrical current, voltage, and resistance. It has a number of features that make it a versatile and reliable tool, including:

• True RMS measurement: This means that the 373 can accurately measure AC signals of any waveform, including those that are distorted or noisy.
• High input impedance: This helps to prevent the 373 from loading down the circuit being measured, which can lead to inaccurate readings.
• Backlit display: This makes it easy to read the display in low-light conditions.
• Data hold: This allows you to freeze the display of a measurement so that you can take a closer look at it.
• Auto ranging: This eliminates the need to manually select the measurement range, which can save time.

The 373 also has a number of features that make it a safe and easy-to-use tool, including:

• CAT III 1000 V safety rating: This means that the 373 can be used safely to measure voltages up to 1000 V.
• Non-contact voltage detection: This allows you to quickly and safely identify the presence of voltage without having to touch the wires.
• Ground fault protection: This helps to protect you from electrical shock.
