1. Chromatic LCD display: Friendly human-computer interface, large-screen LCD display every technical parameter in real time. 2. Input function of the injector inner diameter: Can choose the injector from the list or input the injector inner diameter directly. 3. Inject fluid measure and rate can be set up according with the demand. 4. Fluid measure calibration function: Through the calibration procedure can get more accurate flow. 5. Display the inject fluid measure in real time, after finish the set value, it will stop work automatically. 6. Can check and adjust the parameter during injecting. 7. Working mode: 5 different working model—Infusion, withdrawal, infusion/withdrawal, withdrawal/infusion, continuous. Every working mode technical data save separately, do not influence each other. 8. Memory Function: The parameters are saved in EEPROM. The parameters don’t need to be reset when power returns after an interruption. In flow rate mode, the pump remains or stop according to the setting parameters when power returns. 9. Block Protection Function: The pump will stall and give an alarm when the drive structure of the pump is blocked. 10. External Control Function: Input/Output control. 11. Communication Function: Realize computer control through RS485, control the working status from the backstage. 12. Syringe Protection Function: syringe rest to prevent syringe from damaging.
