Customer Questions & Answers
-
Question:
What features does the Extech EX655 Clamp Meter offer?
Answer: The Extech EX655 Clamp Meter features True RMS measurement for accurate readings in varying waveforms, a 600A AC/DC current range, non-contact voltage (NCV) detection, and temperature measurements from -40 to 752°F (-40 to 400°C). This combination makes it suitable for various electrical tasks, such as troubleshooting circuits or performing maintenance checks on HVAC systems. Its portability with an easy-to-read display allows professionals and DIY enthusiasts alike to efficiently assess electrical systems. -
Question:
How does the True RMS functionality work on the EX655?
Answer: True RMS functionality calculates the effective value of varying waveforms, offering accurate measurements even in non-sinusoidal conditions. Unlike averaging meters that can give misleading readings, the EX655 ensures that readings reflect actual performance, making it reliable for diagnosing complex electrical issues. For electricians and technicians, this reliability is essential when working with modern electronic devices that often produce distorted waveforms. -
Question:
Can the Extech EX655 measure both AC and DC currents?
Answer: Yes, the EX655 can measure both AC and DC currents up to 600A. This versatility allows users to work on various electrical systems, from residential to industrial applications. Whether you're testing the current draw of appliances or troubleshooting circuits, having the ability to measure both types of current expands usability and ensures effective diagnostics across different environments. -
Question:
What safety features are included with the EX655 Clamp Meter?
Answer: The EX655 is designed with safety in mind, featuring Category IV 600V safety ratings that protect users when working with high-voltage lines. Other features include a protective rubber holster and overload protection, ensuring that the device absorbs shocks and prevents electrical damage. For technicians working in environments with high voltage or fluctuating currents, these features help maintain safety and provide peace of mind. -
Question:
How does the non-contact voltage (NCV) feature work?
Answer: The NCV feature on the EX655 lets users detect voltage without making physical contact with electrical conductors. When the clamp meter is close to an energized wire, it will alert users with audible beeping and a visual indicator. This is particularly useful for safely identifying live wires in crowded electrical panels or troubleshooting circuits, as it minimizes risk during electrical diagnostics. -
Question:
What types of temperature measurements can the EX655 perform?
Answer: The EX655 can measure temperatures ranging from -40°F to 752°F (-40°C to 400°C) using an external thermocouple. This capability makes it ideal for troubleshooting HVAC systems, monitoring motor temperatures, or assessing electrical device heating. Using the clamp meter’s temperature measurement feature enhances a technician's ability to conduct thorough and effective diagnostics without needing separate tools. -
Question:
Is the EX655 suitable for beginners in electrical diagnostics?
Answer: Yes, the EX655 is user-friendly and features an intuitive interface, making it suitable for beginners while still providing advanced functionalities for professionals. It includes a large backlit display for easy reading in different lighting conditions and a simple button layout. Whether you’re a DIY enthusiast or a novice technician, this tool can help you safely measure electrical parameters without an extensive learning curve. -
Question:
What is the display size and type of the EX655?
Answer: The EX655 features a large LCD display that is easy to read, even from a distance or in dim lighting conditions. The backlighting enhances visibility, ensuring that readings can be viewed clearly during use. This is especially useful for technicians working in less-than-ideal environments, where frequent movement in and out of light can make reading smaller displays difficult. -
Question:
What is the maximum jaw size of the EX655 Clamp Meter?
Answer: The maximum jaw opening of the EX655 is 1.5 inches (38 mm), allowing it to clamp around substantial conductors. This is beneficial for both residential and industrial applications, where large cables may be present. It helps users easily measure current in thick wires without needing to make any modifications, thus preserving the integrity of the circuit being tested. -
Question:
Where can I buy Extech EX655 True RMS 600A Clamp Meter with NCV and Temperature Measurements in UK?
Answer: You can purchase the Extech EX655 True RMS 600A Clamp Meter with NCV and Temperature Measurements on Ubuy. Ubuy offers a seamless shopping experience with an extensive collection of tools and electronic devices, ensuring a reliable source for advanced testing equipment like the EX655.
Extech Multi Testers Editorial Review
The Extech EX655 True RMS 600A Clamp Meter is a versatile tool designed for indoor applications. While it claims to measure motor starting amperage, the accuracy is questionable and the disclaimer regarding accuracy is a key point to note. The display is difficult to read and the instrument response rate is slow. Additionally, there is a design flaw in the autoranging function that locks the max current reading at OL on a 60A range before switching to the 600A range. Overall, this meter may not be the most reliable option and it might be worth considering other brands like Fluke.
