vi. Check Water in tube:

  1. downloading data
  2. If Swapping Li-7500 Analyzer. (Remove SN# ; install SN# )
  3. Check the fans of air temp. and relative humidity sensors
  4. Check MD-9 system connections
  5. Check CR23X with two multiplexers and sensor values
  6. Check levels of Radiation sensors, clear up surfaces.

Closed gate and set up fence.
