Your chlorine is a little high for such a low CYA , but it will come down quickly. When was the last time you added any CYA or used any stabilized form of chlorine meaning trichlor pucks or dichlor shock powder?
Your pH is ok at 7.6 but your TA is really high. You'll need to lower it. More info about how to do that can be found at this link:

You must have been using some cal-hypo since your calcium reading is at 270. I would just stick with bleach instead of cal0hypo. With high hardness and high TA, your pool may get cloudy. Lower alk and then use bleach to avoid that problem. If you tell us the volume of the pool, we can help with dosing amounts for bleach.
