[1] Specifications
indicate the maximum flatness deviation from DC, and include both measured AC-DC difference and the
uncertainty of measurement. They
are stated at k=2, approximately 95 % confidence
[2] Includes 1-year stability of the AC-DC difference
[3] Specifications
for the 1 mA Current Shunt are for TCal ±1 °C

[1] Longer than 5 seconds may cause permanent damage to the shunt. The output voltage may be considerably higher than 0.8
V.
[2] Exceeding maximum sustained current may cause a resistance value step change
[3] 1 mA shunt batteries should be fully charged to ensure performance at 2 mA
