AI Absolute Accuracy

Absolute accuracy at full scale numbers is valid immediately following internal calibration and assumes the device is operating within 10 °C of the last external calibration. Accuracies listed are valid for up to one year from the device external calibration.

Absolute accuracy at full scale on the analog input channels is determined using the following assumptions:

•         TempChangeFromLastExternalCal = 10 °C

•         TempChangeFromLastInternalCal = 1 °C

•         number_of_readings = 10,000

•         CoverageFactor = 3 σ

Maximum Working Voltage

Maximum working voltage refers to the signal voltage plus the common-mode voltage.

Measurement Category I is for measurements performed on circuits not directly connected to the electrical distribution system referred to as MAINS voltage. MAINS is a hazardous live electrical supply system that powers equipment. This category is for measurements of voltages from specially protected secondary circuits. Such voltage measurements include signal levels, special equipment, limited-energy parts of equipment, circuits powered by regulated lowvoltage sources, and electronics.

Caution Do not use the NI PXIe-7858R for connection to signals in Measurement Categories II, III, or IV.

Note Measurement Categories CAT I and CAT O (Other) are equivalent. These test and measurement circuits are not intended for direct connection to the MAINS building installations of Measurement Categories CAT II, CAT III, or CAT IV.

[1] The minimum measurement voltage range is the largest voltage the NI PXIe-7858R is guaranteed to accurately measure.

[2] The minimum measurement voltage range is the largest voltage the NI PXIe-7858R is guaranteed to accurately measure.

[3] NI recommends minimizing long-term over/under-voltage exposure to the Digital I/O. Prolonged DC voltage stresses that violate the maximum and minimum digital input voltage ratings may reduce device longevity. Over/under-voltage stresses are considered prolonged if the cumulative time in the abnormal condition exceeds 1 year.
