Summary: Swapped HMP60 for a HMP45, replaced plywood in upper boardwalk, uploaded new CR1000 program, changed CR1000 Pakbus address

East End

Joe and I arrived at 14:20. It was clear, sunny, and mild.

Joe replaced the wood of the upper boardwalk with a new piece of 1/2" plywood. Two bolts were rusted and broke off; the middle brace under the plywood is still holding weight and shouldn't move around, but needs L-brackets to secure its position. We borrowed Tyler's battery-powered skilsaw to cut the plywood.

I checked the Air T and RH data. The RH had been 0 since 2019-01-10, and a power-cycled fixed it. The Air T seemed low, so I decided to swap the sensor. It was 13C when all the other temperatures were ~17C (7500, NR01 PRT, Panel T, and AM25T RefT. HMP60 sn G4540023 came off and HMP45 sn U3030046 went on. After the swap, AirT = 14.5 and RH = 13.2. RH seemed low so we should check it next time.

I wired the HMP45 as a differential sensor and uploaded a new CR1000 program.

I also power-cycled the barometer, after which AtmP match the 7500 air pressure (~102.5-102.6).

I added a sn 47110 label for the CR1000 and changed its Pakbus address from 1 to 10.

We had to leave the extra plywood here because we didn't have straps to bring it home, so we can bring straps next time.

We left at 15:55.
