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

Current source has an absolute accuracy of ±5%.
30
Refers to source lead resistance. Sense lead resistance is limited only by noise considerations. For best results, it is suggested that it be limited to 1.5k.
31
Offset compensation voltage plus source current times measured resistance must be less than source current times resistance range selected.
32
For 2-wire mode.
33
Current source is paralleled with a 10M resistance.
34
Specifications are for 10 power line cycles, 10-reading repeat digital filter, synchronous autozero, autorange off, 4-wire mode, offset compensation on (for 20 to
20k ranges), except as noted.
