[1] Stated accuracy is attained when Zero function is used.

Temperature (8846A only)

Test Current........................................................... 1 mA
Accuracy is stated as ± °C and is based on a Platinum RT100 (DIN IEC 751, 385 type) RTD with less than 10 ohms lead
resistance. The accuracy listed in the table below are valid only when using the 4-wire RTD measurement function.
Specifications do not include probe accuracy, which must be added.
