During the testing period, a 3S interruption of output current will not trigger an alarm, and there should be no current shock phenomenon when transitioning from off to on. 1.3 Data Transmission Requirements ??The instrument must achieve remote measurement and control, with the potentiostat providing a remote data transmission port for output current (I_out), output voltage (V_out), and pipe/ground potential (V_prot). ??The analog input/output interfaces are standard industrial signals of 4-20mA. Switching input/output interfaces are level signals, pulse signals, contact voltage, etc. The voltage value of a high-level signal should be between 20V-24V, and the voltage value of a low-level signal should be between 0-4V. 1.4 Safety Performance ??Insulation Resistance: The insulation resistance between input and case should be >50MΩ. ??Dielectric Strength: The instrument can withstand a dielectric strength test voltage of 2000V between input and case for 1 minute without puncturing or arcing. ??Noise ≤45db 1.5 Protection Performance ??Temperature Protection: When the temperature inside the potentiostat case reaches 65°C, the fan operates at full speed; when the temperature reaches 85°C, the potentiostat automatically shuts down to cool down. The equipment automatically returns to normal operating status when the protection conditions are restored to normal. ??Power Grid Protection: When the power grid voltage exceeds 30% of the rated value, the potentiostat stops operating, and automatically returns to normal operating status when the protection conditions are restored to normal.
