HV Isolog

Isolation measurement of 480 channels at 100-1000 V

HV Isolog

ATV developed the HV Isolog as an isolation data logger for reliability testing of printed circuit board structures. Resistors can be measured from 1 GΩ up to 1TΩ and long-term studies can be performed on up to 480 test structures with a maximum 1kV stress voltage on the isolator.

The system can log 6 temperature sensors and 6 humidity sensors in parallel.


Data Sheet


Measuring Principle


HV Isolog Measuring Principle


The test system can be equipped with up to 12 independent voltage sources. Each source supports up to 40 test structures, so that a maximum of 480 individual elements can be monitored. Up to 6 test groups with different environmental conditions such as temperature and humidity are supported.

The data recording of the individual channels takes place with individual amplifier modules, which measure the leakage currents of the component for the individual test structures. The individual measured data are processed in the connected computer and recorded for the evaluation.
