Table 1. Possible Empirical Accuracy with System Calibration

Table 2. NI PCI-6052E Analog Input Accuracy Specifications

Note: Accuracies are valid for measurements following an

internal (self) E Series calibration. Averaged numbers assume

averaging of 100 single-channel readings. Measurement accuracies

are listed for operational temperatures within ±1 °C of internal

calibration temperature and ±10 °C of external or factory-calibration

temperature. One-year calibration interval recommended. The

absolute accuracy at full scale calculations were performed for a

maximum range input voltage (for example, 10 V for the ±10 V

range) after one year, assuming 100 point averaging of data.
