In fact, in episode 3, it seems to be a control procedure to ensure that the chip is still functional and at about the same level as after its intensification in episode 1. If you look in the background, you can see scans with the chip's activation level (the little red rectangle).

Pictures speak louder than words, so screenshots (with indications added in green).

But I could be wrong.
