DESCRIPTION

The meter UT-502A is a specialized device designed to measure insulation resistance in the range from 0MΩ to 20GΩ.

Attention! High voltage is required to correctly measure the insulation resistance value. During the measurement one should be particularly careful and strictly follow the recommendations included in the device manual.
