If the counting pool is damaged, or if there are too many stains or scratches in its channels that cannot be cleaned, and this affects identification, please immediately replace it with a new spare counting pool. The counting pool should be replaced with the instrument's power turned off.
The counting pool replacement procedure is as follows:
1. Take out the new counting pool, verify that the serial number on the new counting pool matches the serial number on the label in the counting pool packaging box, and then remove the plastic tubes connecting both ends of the counting pool.
2. Open the instrument's front cover.

3. Manually move the microscope objective lens, gently lift the counting pool bracket pressure plate slightly with your fingers, remove the counting pool and bracket, remove the counting pool connection tubes at both ends of the counting pool, and remove the counting pool and bracket as a whole.

5. Install the new counting pool, and connect the six connectors at both ends of the three channels of the counting pool to the counting pool connection tubes according to their colors.
Installation Notes: The installation direction of the counting pool (the side with the protrusion is the front, and the side with the serial number faces inward); the tubes should be inserted to about 2/3 of the connector, as shown in the figure below;

6. Install the counting pool into the bracket, then tighten the counting pool pressure plate screws to secure the counting pool to the bracket.
Installation Notes: When installing the counting pool into the bracket, it should be against the upper right corner of the bracket; the counting pool pressure plate should press against the edge of the counting pool by 1-2 mm.

7. Push the counting pool bracket under the counting pool bracket pressure plate; the positioning steel ball on the pressure plate should fall into the positioning hole of the bracket.
8. After completion, close the instrument's front cover.
9. Enter the counting pool parameters.
After replacing the counting pool, the coefficient of the counting pool needs to be modified in the system software. On the main interface of the system software, click System Management-Instrument Debugging. On the Instrument Debugging interface, click Replace Counting Pool, enter the counting pool coefficient written on the certificate of conformity in the new counting pool packaging box into the corresponding position in the pop-up window, then click the Save button, and then exit.
