Subject: new channels for in-vac sensors 

the new AD590 sensors are physically connected to

  • VME3123, C0 S3 (RCAV)
  • VME3123, C0 S4 (ACAV #2)
  • VME3123, C0 S5 (ACAV #1)

measured across 30kOhm (+/-1%, 100ppm) to gnd, so voltage is ~9V at 30C. Had no precision resistors but doesn't matter as the channels are used for monitoring purposes only

Software channels are not assigned yet.
