When you activate the tricorder your bar in the bottom right goes down, when it empties, you cant use your special abilites. You have to charge them back again at those charge stations. Here's my save if it helps:
LinkBTW looking at the settings part of your save, it lists all unlocked thigns, like collectables, and missions unlocked. If anyone has finished the game, and picked up all collectables cane you ulpload the save and link it, or even just paste the code, e.g /ST/Types/Game/ResearchDataGameplayObjects/HeliosStation01ResearchData,
that would be nice, speciallfy if you cant be arsed to ferrit around finding that last bloody tribble
