Accuracy; System Throughput - Measurement Computing PCI-DAS6013 User Manual

PCI-DAS6013 and PCI-DAS6014 User's Guide

Accuracy

200 kS/s sampling rate, single channel operation and a 15-minute warm-up.
Accuracies listed are for measurements made following an internal calibration. They
are valid for operational temperatures within ±1°C of internal calibration temperature
and ±10°C of factory calibration temperature. Calibrator test source high side tied to
Channel 0 High and low side tied to Channel 0 Low. Low-level ground is tied to
Channel 0 Low at the user connector.

System Throughput

Condition
1. Single channel, single input range
2. Multiple channel, single input range
3. Single channel, multiple input ranges
Note: For conditions 1-2 above, specified accuracy is maintained at rated throughput.
Condition 3 applies a calibration coefficient which corresponds to the range value
