Fan screens on pump box are clogged with debris. Little or no air flow.

Remove CR10X program SI_19 and install SI_20

CR23X battery is lead calcium chemistry.

Theta probes are causing problem in AM416 mux whenever probes are powered up. Leave powered off. No Theta probe data being collected. Noticed PRT reading showed
–263 degree C. This explains the drop outs we are seeing in the data.

Check pressure resolution and logger P02 command is on 2500 mV scale. Pressure xducer is 2200 mV so resolution is correct.

Sonic anemometer crashed no xmit led flashing. Power down and then up twice and sonic begins to function.
