5. Take down

Before removing the TSI from the tripod the operator should set:

  • Vertical and horizontal slow motions to mid-run, and,
  • Leveling screws to mid-run.

Unless specifically stated in the instrument's manual, the horizontal and vertical motions should be left unlocked when the TSI is placed back in its case. If the TSI is brought in from a cold working environment, its case should be left open when stored to allow it to warm up faster and condensation to evaporate.

Tripod leg locks should be set to prevent the legs extending as the tripod is moved. If the tripods is put away cold, the leg locks should be closed just firmly enough to prevent leg extension. If they are fully locked, they could "freeze" if the tripod is next used in a warmer situation.
