Draft: ramp down LV and wait for temperature to stabilise

  • This MR addresses concern of thermal shock after discussion with Hide.
  • Sensor IV characteristics are very sensitive to temperature. We switch off LV for IV in order to make the temperature on the sensor uniform and more accurately measured by the module NTC without the chips heating from below.
  • To avoid thermal shock when doing cold testing, this MR ramps down the LV and waits for the temperature to stabilise for up to 5 minutes.
  • Also ramps up the LV at the end.
