PERFORMANCE
Thus, in operation under the specified conditions (Pr at
70°C) the total drift (load life + T.C.) of a RCMS K3 does
not exceed ± 0.5%.
NOISE LEVEL
In a frequency decade, the average noise level increases
with ohmic value and can reach 0.3 µ V/V for the highest
values. It is non measurable for Rn < 2 kΩ.
