For example,

1. User can measure the voltage between working and reference electrode and, by using 2 additional analog inputs (auxiliary voltage input), user can also measure the voltage between reference and counter electrode and working and counter electrode as well.
2. With analog output, the system can control rotating speed of the rotator, MFC flow rate etc. by ±10V full scale.
3. User can control on/off of max. 3 devices by DO etc.

Safety and Maintenance:

1. Even though the communication failure occurs between PC and ZIVE SP2, the system continues its experiment on channel and saves the data into ZIVE memory up to 295,000 data point set. After the communication is restored, ZIVE will transfer saved data to PC automatically or user can transfer data when he / she wants. This function will be highly efficient for long time experiment.
2. User can define a safety condition setting by inputting his/her own safety levels for voltage, current, temperature etc. If the measurement value exceeds this setting value, the system will automatically stop to protect the system and cell.
3. If the control value of voltage or current is different from measured value, the experiment will stop automatically to protect the cell.
4. Automatic calibration function is available for user calibration.
The system is controlled from a PC via USB.
