4.6 Flow calibration
The purpose of calibration is to improve the accuracy of equipment operation; In the setting interface, click "flow rate calibration" to enter the flow
calibration interface. Calibration requires the use of a measuring cylinder. The device is equipped with a 10ML measuring cylinder at the factory.
Considering the different concentration of the titration solution of the equipment tube and the degree of aging of the equipment tube, calibration is
required for the first use. When the titration is inaccurate, it should be calibrated in time.
a. Flow Calibration：：click flow rate calibration on the setting interface to call up the flow rate calibration channel selection interface;
b. Rotation：： set the calibrated speed;；
c. Start emptying：：The purpose of evacuation is to let the air out of the equipment tube, so that the accuracy will not be affected during the
