Details:
VLF Advantages:
1. Easiest to use Fully automatic microcontroller
2. Built-in printer
3. True sine wave output
4. Real-time display of actual output waveform
5. Ergonomic, menu guided, large backlit LCD
6. Storage of test results for later retrieval and print. True Sine Wave
7. Over voltage and current protected
8. Variable frequency 0.1Hz, 0.05Hz, 0.02 Hz, 0.01 Hz (4 position)
9. Data of current, voltage and waveform directly sampled at HV side.
10. AC testing does not degrade good cable insulation
11. Harmful space charges are not injected into the cable insulation
12. No traveling waves are generated during testing
13. Rugged and reliable design less prone to failure from transients
14. Invatation Patent

Safety Features
