Basic capability
– 0 = Alarm and critical trips turned OFF.
– 1 = Alarm and critical trips turned ON.
Accuracy
– 0 = Accuracy ±2 °C over the active range and ±3 °C over the monitoring range
– 1 = High accuracy ±1 °C over the active range and ±2 °C over the monitoring range
Range width
– 0 = Values lower than 0 °C will be clamped and represented as binary value '0'.
– 1 = Temperatures below 0 °C can be read and the Sign bit will be set accordingly.
Temperature resolution
– 01 = This 10-bit value is fixed for STTS424E02, providing temperatures at 0.25 °C
