Analog settling & integration timing

[patricktokeeffe]

Non-default values are being used in several locations for Settling Time and Analog Integration Time. It's unclear if these represent arbitrary choices, or are optimal selections based on lab experiment, or are hold-overs from converting between logger types.

Group A (CR1000X)

• fine wire thermocouples
  • settling time: 450 vs 500 (def)
  • fN1: 250 vs 15000 or _60Hz
• panel temp
  • fN1: 250 vs 15000 or _60Hz
• component (4 channel) radiometer, incl. self-temp
  • fN1: 15000 (= fast integration, 0.0667 millisecond) ✓
• PAR sensor
  • fN1: 15000 ✓
• T/RH probes (x4), via mux
  • fN1: 15000 ✓

Group B (CR1000X)

• fine wire thermocouples
  • settling time: 450 vs 500 (def)
  • fN1: 250 vs 15000 or _60Hz
