10. The overcurrent protection device has sufficient sensitivity to ensure that the power is cut off within 0.1 seconds when the sample breaks down;
11. Durability of instrument operation: The instrument can operate continuously without the need for periodic shutdowns to protect it.

Software operation interface:

Parameter settings:

Performance characteristics:

（1）Threshold protection: If the door is not closed, even if the power on point experiment starts, the device will not respond, and the software will prompt that the safety door is not closed.
(2) Voltage zeroing protection: If there is a sudden power outage during the experiment, it will automatically return to zero position after the next power on, ensuring that the initial voltage is at zero position
(3) Termination voltage protection: The termination voltage can be set through software to ensure that if there is an abnormal voltage rise during the boosting process, it will automatically terminate and return to zero
(4) High voltage mechanical limit: If the software system loses control and the voltage continues to rise, it will automatically return to zero after reaching the high voltage limit. If it does not stop after breakdown, data will be collected through an overcurrent protector to ensure that the voltage automatically returns to zero. There is a high voltage indicator light, and the status of the indicator light can be observed to determine whether the voltage is actually rising or at zero. If the experiment is conducted for a long time, in order to ensure the good operation of the equipment, the equipment has a transformer exhaust port to ensure the good operation of the transformer and increase the service life. If there is any odor or burning and smoking phenomenon in the sample during the experiment, it can be eliminated through the exhaust system.
