At each 10°C temperature increment, the Autonomous SmartCal™ board calibrates in less than 300 ms its analog section before digitizing a known voltage input. Each point on the graph shows how the measured value differs from the known value in Least Significant Bits (LSB). Accuracy is within ±½ LSB.

RTD’s operating system independent unique Autonomous SmartCal™ sets a new industry standard for data acquisition precision and accuracy over a wide temperature range
