[1] Add to uncertainty when more than 5 ° C from calibration temperature.
[2] Input capacitance approximately 100 pF.
Note: DC specification valid only when dc input signal is averaged with an equal and opposite dc input signal to eliminate dc offset
errors. The use of Input 1 for dc inputs is not recommended due to the inherent thermal EMFs in a “N” connector. See Operators
Manual for details.
