Dear Peter,
1. Time between the temperature points is about 2 minutes.
(temperature rate is 1 degree per 2 minutes)
2. We measure 4-20 mA sensor signal with 301 Ohm resistor,
followed by a unity gain amplifier and 16-bit ADC with the
range of [+ - 10V]. This gives about 0.3mV resolution.
Total ADC error is about +- 2 LSB [+- 0.6 mV].
Best regards,
Peter-the-second.
