3. Safety Information

The ECT300 is designed with multiple protection measures to ensure safe operation and prevent damage to the device and vehicle components.

Overcurrent Protection: Responds in milliseconds to prevent damage from short circuits or excessive current.
Overheat Protection: Activates if the test circuit temperature reaches a high level, requiring the device to cool down before further use.
Reverse Protection: A diode conducts in the forward direction and cuts off in reverse, protecting the circuit from incorrect power supply connections.
Short Circuit Protection: An internal circuit breaker system automatically trips for protection if the current is overloaded.
