Furthermore, the general Etekcity Digital Clamp Meter & Multimeter user consensus was that the included instructions were relatively clear and detailed.One Etekcity Digital Clamp Meter & Multimeter user tested the voltage and amperage measurements against the Fluke T5-600. This user claims that the meter’s amperage measurements were virtually the same. The readings from the Etekcity meter were about 0.1 amps from the Fluke meter readings.The Etekcity Digital Clamp Meter & Multimeter has a well-performing auto-ranging feature, as well as good repeatability. The probe tips are also very nice.

While the meter is not ideal for professional use, it is great for DIY and simple home readings.A concern of one Etekcity Digital Clamp Meter & Multimeter was that he could not find a UL listing on the multimeter or in the instructions manual. Another user tested the continuity feature on the meter.

While the probe tips did indicate continuity upon contact, this user thought they were not as sensitive as similar meters. One more user concern is that the current reading clamp did not work properly on the meter.One Etekcity Digital Clamp Meter & Multimeter user advises that this meter is not a true RMS meter, but rather a clamp AC current meter. As an AC clamp meter, this is an excellent choice for the price.
