34901A, 34902A, and 34908A Temperature Measurements Out of Specification
It was discovered that the module cards 34901A, 34902A and 34908A were incorrectly calibrated in production. Inaccurately calibrated temperature sensors on these cards will cause thermocouple measurement error only using the internal temperature reference to exceed published specifications.
The mis-calibration only affects thermocouple measurements that use the internal reference, but does not affect thermocouple measurements using external and fixed temperature references. Other measurements such as voltage, resistance and current are not affected by this issue.
Please refer to Service Note 34901A-04, 34902A-06, and 34908A-04 for more details.
