I performed another continuity test on the RTD chassis wiring, and everything seems to be set up correctly. The chassis should be ready for installation.
Below is the current state of the RTD readout chassis wiring. Initial continuity tests seem good, will run through one more time to confirm.
The custom front and rear panels for the RTD readout chassis arrived last Friday. I installed them in the chassis frame to check their fit. They fit very well, so all that now remains is to complete the internal wiring and test the connections.
The chassis panel designs are archived to LIGO-D2300452 and LIGO-D2300453.
Below are a basic diagram of what the RTD measurement circuit logically looks like and an example schematic of the actual wiring. The schematic wiring will be placed internally into a chassis, connected to the RTDs via DB25 cable.
Below is the proposed schematic for FROSTI optical testing, chosen so enough space is allotted for prototype assembly.
Steps to be taken include:
Tentative plan is to begin setup early next week.
Group Meeting slides for Non-deterministic Heater Response.
