Product Description

The Amprobe AMC-3 hand cranked insulation tester is an analog meter to measure insulation resistance on wires, cables, transformers, and electrical motors. The unit measures insulation resistance from 0 to 1,000 Megaohms using a 1,000V direct current (DC) test voltage. It also has a low-resistance range that measures from 0 to 200 ohms with a 300mV DC test voltage. The test voltage is produced by a hand-cranked constant voltage generator, so the unit never needs batteries. A guard terminal prevents surface leakage from affecting the instrument's readings. The AMC-3 is designed for use by electricians and electrical contractors.


Power supply Hand-cranked constant voltage generator
Insulation resistance range 0 to 100 Megaohms, 0 to 200 ohms
DC test voltage 300mV or 1,000V
Weight (including batteries) 2.5 lb./1.13kg
Dimensions 7 x 4 x 3.6 inches/177.8 x 101.6 x 92.1mm (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.

Electrical test meters report electrical circuit properties, such as voltage, resistance, capacitance, and continuity. Available in handheld or benchtop form, they detect electrical problems in equipment, wiring, and power supplies. A variety of probes, clamps, and leads can be used to connect the meter to a circuit or device. Single-function meters, such as battery testers and voltage testers, measure one property of a circuit, and multimeters measure multiple properties. Electrical test meters display information either in analog form using a needle that moves on a calibrated scale, or in digital form using digits or a graphic representation on an LED screen. Meters have electrical properties that are to be measured and the anticipated range of results, and should have a rating that is higher than the maximum value of the anticipated range. An electrical test meter has multiple settings corresponding to potential ranges of values for the properties it can measure. A manual ranging meter requires the operator to flip through different settings until the correct range is reached. An autoranging meter cycles through range settings automatically until it reaches the correct range.

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