Description
Description
The Testkey TK2691 insulation resistance testers measure insulation resistance and leakage current with programmable DC test settings.
Choose the model whose resistance range and DC test-voltage limit match the test. Charging time and measurement delay can each be programmed from 0 to 999 seconds.
