Real-World Testing: Putting Extech Instruments Clamp Meter with DMM, Mini to the Test
First Use Experience
My first real-world test was troubleshooting some wiring in a cramped junction box on a commercial HVAC unit. The confined space made using a standard-sized clamp meter nearly impossible. The Extech Instruments Clamp Meter with DMM, Mini, however, slipped right in.
It was raining that day, adding another layer of difficulty. The meter’s grip was secure even with damp hands, a critical detail in those conditions. Using the clamp function to measure current was easy and intuitive, and the readings appeared accurate compared to what I expected based on the circuit design. There were no issues at all.
Extended Use & Reliability
After several weeks of use, the Extech Instruments Clamp Meter with DMM, Mini has become my go-to meter for most electrical troubleshooting tasks. The meter has been subjected to a variety of environments, including dusty workshops, damp basements, and hot attics, and has consistently performed flawlessly.
I’ve noticed only minimal signs of wear and tear, mainly minor scuffs on the plastic housing. Cleaning is straightforward; a quick wipe with a damp cloth is usually sufficient. Compared to my old, bulky Fluke meter, the Extech Instruments Clamp Meter with DMM, Mini is easier to handle, more portable, and just as reliable. It definitely outperforms my generic clamp meter in terms of accuracy and build quality.
