Product Description

Style: LH41A: AC/DC 1MA Res. Leakage Clamp Meter

The Amprobe LH41A digital clamp ammeter is an average-sensing, auto-ranging meter for measuring current in electrical testing applications. It has a transformer clamp that measures alternating current (AC) or direct current (DC) to 40 amp. The Hall effect clamp has two jaws that can close around an electrical conductor up to 0.78" (20 mm) in diameter to measure current without touching or interrupting the circuit. The zero adjust function compensates for changes in output voltage due to environmental conditions. The hold function keeps the reading on the display, even after the meter is disconnected. The unit automatically turns off after 8 minutes of non-use to conserve battery life. A finger guard on the body of the meter helps protect fingers from shock.

This average-sensing, or average-responding, meter provides accurate readings when measuring linear loads, such as standard induction motors and incandescent lights, where the current or voltage has a sinusoidal waveform. This auto-ranging meter automatically selects the correct operating range for the property being measured. The meter has a 4,000-count resolution, meaning that it can display up to 3,999 units (3-3/4 digits) before the operating range needs to be changed. The meter meets International Electrotechnical Commission (IEC) safety standard 61010 and is certified for category III installations up to 300V, which covers items used with enclosed building circuit installations (service panel parts, branch circuits, and fixed installations that are connected directly to a building's AC power supply). The unit comes with a soft vinyl carrying case.

Specifications

Maximum alternating current (AC) input40 amp
Maximum direct current (DC) input40 amp
Power supply 9V PP3, NEDA 1604 or IEC6LR6 battery (one, installed)
Standards met and certificationsInternational Electrotechnical Commission (IEC) and European Normal (EN) safety standard 61010-1; European Conformity (CE)
Weight0.5 lb./235 g
Dimensions7.2 x 2.8 x 1.6 inches/184 x 71 x 31 mm (H x W x D)

H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Clamp meters (also called clamp-on meters) measure electrical current without cutting through wires or touching or interrupting the electrical circuit. Available in handheld or benchtop models, clamp meters diagnose problems in electrical equipment, wiring, and power supplies. The meter's current clamp has two jaws that fit around a conductor to take measurements. All clamp meters test for current. Some come with test leads and inputs for measuring voltage, capacitance, and resistance. They display information either in analog or digital form. Factors that influence meter choice include the electrical properties to be measured, the anticipated range of results, and the desired level of protection against transient voltages determine meter choice. Safety ratings are based on the International Electrotechnical Commission's (IEC) standards for low-voltage test equipment. IEC 61010 delineates four overvoltage installation categories. In general, a meter with a category IV rating will provide more protection against transient voltages than a meter with a lower category rating.

Amprobe manufactures electrical testing equipment for commercial, industrial, and home use. The company was founded in 1948 and is headquartered in Everett, WA.

Style Name: LH41A: AC/DC 1MA Res. Leakage Clamp Meter Verified Purchase
The LH41A is a tool that is recommended by Honda and Acura to diagnose causes of parasitic draw on the vehicle battery, I was extremely pleased to find one here on Amazon for a reasonable price compared to other websites and tool distributors. It has performed flawlessly and has saved me time and hassle when having to work with sub par shop tools.
