6 calibration

Calibrate

Chapter overview
This section describes the initial setup of the machine and how to modify the factory parameters.
Before calibrating the machine, it is necessary to read the contents of [1.4 General Safety Instructions] and fully understand the safety risks of the equipment.
A single pump runs continuously or intermittently for a total of 9hours, and the pipeline needs to be calibrated once to ensure the accuracy of the product, and the actual operation time is about 3 months. If the output quantity is not accurate during the operation of the store, the whole machine or individual channels can be calibrated at any time.
6.1 Factory calibration/defaults
Ø Calibration principle
The device writes default values before it leaves the factory.
The default value is inaccurate, because of the individual differences of each pump and pipeline, so that the water outlet speed of 1~16 channels is in the range of 2g/s~4g/s, and the values are not equal.
In the factory, after the equipment writes the default value, it will be calibrated with pure water to obtain the actual water speed of 1~16 channels, and automatically save it inside the equipment.
After long-distance transportation, severe bumps and jitter, the water outlet speed of 1~16 may change, and it is necessary to re-use pure water for calibration.
When discarding the calibration value of the device, the default value is restored.
Calibration steps (take calibration of No. 1~8 syrup pipeline as an example).
Before performing the calibration operation, the tubing needs to be cleaned and the tubing to be calibrated. For details, please refer to [5 Cleaning].
This section only describes the external operation, and the specific screen interaction method can be found in the Luckin Coffee APP operation manual.

1. Using the top clasp handle, open the left syrup drawer.

2. Place the cleaning box (4) with purified water inside the left drawer.
   a) 1000ml of purified water.
   b) Connect silicone stopper adapter (1),
   silicone stopper (2), syrup straw (3).
   c) Immerse the end of the syrup straw in purified water.
   d) Push back into the left syrup drawer.

3. Remove the coaster and place it on a side table.

4. Place the thin scale under the outlet.
   Place the paper cup on an electronic scale under the liquid outlet.
   Pay attention to the edge of the weighing cup and do not touch the machine, so as not to affect the weighing accuracy.

5. Click the scale’s “Tare Peel” button Select the tubing you want to calibrate on the screen and click the Calibrate button.
   The machine will use the selected line to discharge a certain amount of purified water into the paper cup.
   After the electronic scale indicator number is stable, read the electronic scale value.

6. Enter the scale value into the screen.
   Follow the on-screen prompts to determine whether you need to drain and weigh again, and enter the weighing value.
   When the calibration is complete, the screen will prompt “Calibration successful”.
   Select different pipes and cycle through 5~6 steps until the calibration of all pipes in the left syrup drawer is completed.

7. Remove the paper cup and scale.
   Dispose of the water in the paper cup.

8. Open the left syrup drawer.
   a) Separate the silicone plug adapter (1) and the silicone plug (2), and the silicone plug adapter is hung on the hook of the drawer beam.
   b) Remove the silicone stopper and syrup straw (3), clean and dry and insert back into the corresponding syrup bottle.
   c) Remove the washing box (4) from the drawer, drain the remaining water in it, rinse and dry it before preservation.

9. Using the top clasp handle, close the left syrup drawer.

10. Insert the coaster into the device with the center of the coaster aligned perpendicular to the outlet.

To calibrate the 9~16 syrup line, please use the right syrup drawer, and the rest of the operation is the same as the 1~8 syrup.
The entire line in the drawer can be calibrated at once or individual tubing.
After the calibration is completed, the syrup line filling is required before operation, please refer to [4.3 Replenishing the Syrup Drawer and Filling the Line].
