 security

1. High voltage circuit has to start, stop buttons and dual foot switch insurance circuit, the safety and reliability of the instrument operation is higher.
2. High voltage output circuit with high voltage display digital table, can display high-voltage equipment at work, In the digital table shows changes to "0", reminding the operator to swap the motor (coil), Avoid high-pressure switch motor(coil), increase the safety of use. At the same time with a warning  when  the instrument is working, light serve as a warning.
3. Output high voltage wires with 30 kv line of silicone pressure. Fixture with large size, and good elastic clamp,Make better contact with the motor and fixtures.

 Reliability

Thyratron, filament, and trigger of the transformer with low voltage work mode, greatly reduces the voltage of high voltage auxiliary power supply circuit and operating voltage of trigger transformer, improves the safety and reliability.

Using high voltage loop isolated high frequency current sensor, and directly display through the thyratron and winding current waveform, to prevent the damage caused by a thyratron overload, at the same time, reduce the interference on the oscilloscope.
