The Amprobe AD40B mini-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) to 400 amp. The clamp has two jaws that can close around an electrical conductor up to 1" (25 mm) in diameter to measure current without touching or interrupting the circuit. The hold function keeps the reading on the display, even after the meter is disconnected. It has a liquid crystal display (LCD) that shows readings both in digits and on a bar graph. The unit automatically turns off after 30 minutes of non-use to conserve battery life, and a low-battery indicator signals when the meter's batteries need to be replaced. 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 600V, 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.SpecificationsMaximum alternating current (AC) input400 ampPower supply 1.5V UM-2 AAA batteries (two, installed)Standards met and certificationsEuropean Normal (EN); International Electrotechnical Commission (IEC) and EN safety standard 61010-1; European Conformity (CE)Weight0.5 lb./250 g Meter dimensions7.4 x 2.5 x 1.4 inches/190 x 64 x 36 mm (H x W x D)H is height, the ver...
