In an ideal world, all wires and connections are well insulated. In the real world, however, everything wears out and connections are not perfect. To prevent this from causing problems, it is important to regularly test electrical systems for insulation. Insulation resistance meters test whether the insulation of cables is sufficient. This prevents problems such as short circuits. This measurement is important to repeat regularly because of corrosion and wear and tear.

The UT511 is an insulation resistance tester. The meter is built from a microprocessor and equipped with good measurement and data processing software. The meters are essential to determine whether equipment and cabling are sufficiently insulated to cope with certain voltages.

The meter can measure up to one kV and can do both AC and DC measurements.
