KAGRA VIS Operations Manual - Thermometers
There are temperature sensors in many locations. They use LS26500 batteries, which should be changed if the LCD display stops displaying or the temperature signal in the digital system stops updating. Spare batteries are stocked in the tent. Remove the two screws in the back of the case with a small plus driver and pry open the case with a small minus driver. After changing a battery, update the list at KAGRA/Subgroups/DGS/Projects/Rem/History.
