Agilent Technologies U2802A System accuracy without thermocouple sensor error, =0.95 C, =4.6 C

4 Product Specifications

Therefore,

ETHERMOCOUPLE = 0.75% × 600 °C = 4.5 °C

Using the above individual component errors, the total measurement system accuracy is calculated as below.

System accuracy without thermocouple sensor error:

ETOTAL

=SQRT(EDAQ2 + ESIG_COND2 + EZEROING2 + ECJC2)

=0.95 °C

System accuracy with thermocouple sensor error:

ETOTAL

=SQRT(EDAQ2 + ESIG_COND2 + EZEROING2 + ECJC2 + ETHERMOCOUPLE2)

=4.6 °C
