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

Closed gate and set up fence.
