Specifications are for 4-wire resistance, offset compensation on for ≤10 kΩ measurements, and offset compensation off for ≥10 kΩ
measurements. 1 Ω range is 4-wire only. For 2-wire, with Rel, add 50 mΩ to ppm of range uncertainty. Without Rel and with Model 1756 test
leads, add 100 mΩ to ppm of range uncertainty.

Specifications are for external cable and load capacitance < 1 nF.
25
For offset compensation on, add 10 ppm of uncertainty to ppm of reading.
26
For 4-wire, 1 MΩ, open lead detection on, add 10 ppm uncertainty to ppm of reading.
27
Specified for < 10 % lead resistance mismatch in HI and LO.
28
Open circuit voltage is typical, measured from input HI to LO, SHI and SLO open. For 1 Ω to 1 MΩ ranges using an external digital multimeter
(DMM) set to 10 MΩ input impedance; for 10 MΩ to 1 GΩ ranges, set external DMM to >10 GΩ input impedance.
