​​Other settings: 
  • ​​FUSE LINKING:
  • ​​REF DAQ → REF VBB
  • ​​REF VBB → REF DAQ
  • ​​FUSE LINKING:
  • ​​PMT 1 → PMT 2 
  • ​​PMT 2 → PMT 1
  • ​​FUSE DELAY for all channel 100ms (gives 100ms to settle before testing if it is above the limit)
  • ​​OVER VOLTAGE PROTECTION: 
  • ​​REF DAQ works at 5V, so we set to 5.5 V (make sure that it does not get exposed to over tension)
