- Insulation resistance meter with built-in voltmeter to test insulation of wires, cables, transformers, surge arresters, generators, and electrical motors.
- Digital meter with automatic range selection.
- Internal memory stores up to 18 measurements for later download to PC using USB.
- Measures voltage from 30 to 600V AC or DC and insulation resistance from 0 to 1 teraohm with 500, 1,000, 2,500, and 5,000V DC test voltage.
- Safety rated to European Standard EN 61010-1 Category III 600V.
The Amprobe AMB-50 industrial high-voltage insulation resistance
tester is a digital meter that measures insulation resistance and
voltage to help reduce shock hazards and downtime on electrical
systems that include wires, cables, transformers, surge
arresters, generators, and electrical motors. The tester has
automatic range selection for increased safety. The unit measures
0 to 600V alternating current (AC) or direct current (DC) and
insulation resistance from 0 to 1 teraohms using 500, 1,000,
2,500, or 5,000V DC test voltage. A low-resistance range (0 to
4,000 ohms) is used to measure resistance in motor windings. The
internal memory holds up to 18 test results for later download to
a PC using the included USB cord. The tester is safety rated to
European Standard (EN) 61010-1, Category III, 600V. The unit has
a programmable timer to perform Dielectric Absorption Ratio
Tests, Polarization Index (PI) tests, and comparison tests. The
tester is powered by eight C batteries (included). The AMB-50 is
designed for use by electricians and electrical contractors.

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.
