ground clamp meter

Ground clamp meters commonly measure AC current and AC/DC voltage. Many models also include resistance, capacitance, continuity, diode testing, and frequency. Additional features found on some units include live/zero‑wire detection, true‑RMS capability, and temperature measurement via a probe.

Current ranges vary by model. Examples from the listings include 40–400 A, units rated to 600 A, and digital true‑RMS meters rated up to 1000 A. Always confirm the maximum clamp rating for the specific model you plan to use.

Most ground clamp meters are battery powered, commonly using AAA cells. Listings show some models specified as requiring 2 × AAA (not included) while others ship with the two AAA batteries provided — check the product details for each model.

Typical accessories include test leads, alligator clips, batteries, and a carrying or storage case. Some listings also include connector kits and a storage bag; check the product packing list for model‑specific extras.

Jaw openings in the listings range from about 36 mm (≈1.42 in) up to about 1.5 in. One model notes a double‑open 36 mm jaw. Verify the jaw diameter on the model you choose to ensure it fits the conductors you’ll measure.

Several models include an integrated NCV detector for sensing AC voltage without direct contact. At least one listing highlights a dedicated NCV button for quick AC presence checks.

Display features commonly include LCD or backlit LCD screens, data‑hold and min/max functions, automatic power‑off, and, on some models, a 4000‑count display for more granular readings.

The meters are described as compact and travel‑friendly, with listed weights around 0.82–1.19 lb and compact dimensions. Several models ship with a carrying case and batteries, and at least one listing explicitly describes the unit as durable for travel use.

Function sets vary by model. Examples include an analog meter listing 4 functions with 8 ranges and a digital true‑RMS unit listing 10 functions with 27 ranges. Common functions across listings are AC current, AC/DC voltage, resistance, capacitance, continuity, diode testing, frequency, and, on some models, temperature or true‑RMS measurements.
