Firstly, we should adjust if the temp controller mode is p801. Generally speaking, p801 will be selected as factory setting. If you need to manually adjust water temp, Caution: If there are 10℃ difference between setting temperature and ambient temperature, it is easy to generate condensate water and danger the laser.
Therefore, to extend the laser life, please use p801 intelligent temperature controller which does not need to adjust the controlling parameters under normal circumstance. It will self-adjust controlling parameters according to room temperature for meeting laser cooling requirement.
