System accuracy specifi cations
The U2802A system accuracy specifications are shown in Table 1, Table 2, and Table 3. These measurements are derived
from the U2802A and DAQ input accuracy specifications without including the thermocouple error. Refer to “Calculating
System Accuracy” section in the Agilent U2802A 31-Channel Thermocouple Input Device User’s Guide for calculation
methodology.
