MAX31855EASA+ Frequently Asked Questions (FAQs)

• What is the maximum temperature range that the MAX31855EASA+ can measure?
  The MAX31855EASA+ can measure temperatures from -200°C to 1350°C, with an accuracy of ±1°C from -20°C to 420°C.
• How does the MAX31855EASA+ handle cold junction compensation?
  The MAX31855EASA+ has an internal cold junction compensation circuit that uses an internal thermistor to measure the temperature of the cold junction, and then compensates for it in the thermocouple measurement.
• What is the conversion time for the MAX31855EASA+?
  The conversion time for the MAX31855EASA+ is approximately 10ms, which allows for fast temperature measurements.
• Can the MAX31855EASA+ be used with multiple thermocouple types?
  Yes, the MAX31855EASA+ can be used with multiple thermocouple types, including K, J, T, N, E, and B types, by selecting the appropriate thermocouple type through the device's registers.
• How does the MAX31855EASA+ handle noise and interference?
  The MAX31855EASA+ has built-in noise filtering and interference rejection capabilities, including a 50Hz/60Hz notch filter and a high-pass filter to reject DC offsets.
