Factory calibration uncertainty represents traceability to
NIST. This uncertainty is added to relative accuracy
specifications to obtain absolute accuracies.
The 20
Ω
- 2M
Ω
range uncertainties are equal to the uncertainty
of the respective calibration sources.
The 20M
Ω
, 200M
Ω
, and 1G
Ω
range uncertainties are equal to
the uncertainty of the 2M
Ω
calibration source.
