Amprobe Telaris ISO-PRO Insulation Tester
The Amprobe Telaris ISO-PRO 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 2,000 megaohms using 100, 250, 500, or 1,000V DC test voltages. The unit has a low-resistance range of 0.03 to 20 ohms. The internal memory holds up to 500 test results for later download to a PC using RS232 data interfaces. The tester is safety rated to European Standard (EN) 61010-1, Category III, 600V. The unit has a selectable timer with 0, 10, 30, and 180 second settings. The tester is powered by six AA batteries (included). The Telaris ISO-PRO 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.
