The infusion set is not properly installed (infusion set's model not set) |
Re-install as required (according to manual) |
|
|
|
The drops detector is not installed or installed incorrectly |
Reinstall the drops detector |
|
|
|
No calibration for infusion set |
Calibrate the infusion sets as required |
|
| 2 |
Pipeline drops on case of power off |
The infusion set is not properly installed or does not meet the requirements |
Readjust the infusion set or replace one set |
|
|
|
The parts are damaged, deformed or the screws are loose. |
Re-adjust or replace parts (Adjusted by professionals) |
|
| 3 |
Battery low voltage alarm |
Too long not using the battery or battery insufficient |
Charge in time |
|
|
|
Built-in battery is not used properly, battery damaged or invalid. |
Replace battery |
|
| 4 |
No Display on boot |
Too low battery voltage |
Charge or replace the new battery |
|
|
|
System error |
Restart, if invalid, contact the manufacturer for repair. |
|
| 5 |
Often blocking alarm during infusion |
Infusion line knotted |
Re-check the infusion line |
|
|
|
Set the pressure gear too low |
Increase the pressure gear setting |
|
|
|
Error in pressure detection system |
Contact the manufacturer for repair |
|
| 6 |
Often bubble alarm during infusion |
After using the infusion tube for a period of time, the part of rolling deformation is set in the position of bubble sensor |
Move the position of the infusion tube to let the line part in good condition be set in the bubble sensor, avoiding the deformation part being set in bubble sensor |

Name of Button |
Description |
| 1 |
Increase |
When the cursor hovers over a parameter option to be set, this button can be pressed to adjust the parameter; the parameter value will increase rapidly if you long press this button. |
| 2 |
Stop |
You can press the “Stop” button to stop the on-going infusion operation; parameters can be set in the stop state. After an alarm is sent, you can press the “Stop” button to stop both the device and the alarm signal sent by the device. In the stop state, no other changes will be caused if this button is pressed repeatedly. |
| 3 |
Decrease |
When the cursor hovers over a parameter option to be set, this button can be pressed to adjust the parameter; the parameter value will decrease rapidly if you long press this button. |
| 4 |
Fast Forward |
Click this button in the non-operating state. If you click this button again within 2s and keep pressing it, the system will enter the fast forward state; after loosening, the fast forward action will be stopped, and the system will return to the parameter setting state. If you do not click this button again within 2s, the system will exit the fast forward state, and the fast forward prompt will disappear automatically; at this point, the operation of the “Fast Forward” button will not be included in the total volume. Click this button in the infusion state. If you click this button again within 2s and keep pressing it, the system will enter the “fast forward infusion” state; after loosening, it will return to the normal infusion state. At this point, the operation of the “Fast Forward” button will be included in the total volume. |
| 5 |
Start |
After all parameters are properly set, you can press the “Start” button to start infusion; the infusion pump will enter the infusion state at the same time. |
| 6 |
Enter |
This button is used to set the third-level menus on the LCD screen. |
| 7 |
Select |
This button is used to select and set the second-level menus on the LCD screen; when the “Set” button is used to switch to the corresponding menu, the system will enter the corresponding menu setting interface after the “Select” button is pressed. |
