AT683,100K ohm to 10T ohm insulation resistance tester
The AT688 High Resistance Meter is instrument that adopts high-performance ARM microprocessor. The voltage applied to the device under test (DUT) is programmable from 1 to 1000 volts. A pass/fail indicator provides a visual display of test results based on a preset limit.
The AT688 High Resistance Meter is designed for measuring very high resistance and related parameters of insulation materials, electronic components, and electro-mechanical components.
