System Accuracy Specifications

The Agilent U2802A thermocouple input measurement accuracy with the
U2355A and U2356A is as shown in
N O T E
Table 4-1 U2802A measurement accuracy with U2355A or U2356A, at 23 °C ± 5 °C, with
Agilent U2802A 31-Channel Thermocouple Input User's Guide
• Assume a ±1 °C error in the CJ measurement due to sensor error and temperature
gradient error in the accuracy numbers in Table 4-1, Table 4-2, and Table 4-3 below.
• Table 4-1, Table 4-2, and Table 4-3 are derived from the U2802A and DAQ input accuracy
specifications without including the thermocouple error. Refer to
Accuracy" on page 46 for calculation methodology.
