DC VOLTAGE AUTOZERO OFF ERROR:
For ±1°C and ≤10 minutes, add ±(8ppm of reading + 15µV).
10. Specifications are for 4-wire resistance, offset compensation on for ≤10kΩ measurements, and
offset compensation off for ≥10kΩ measurements. 1Ω range is 4-wire only. For 2-wire, with
Rel, add 50mΩ to ppm of range uncertainty. Without Rel and with Model 1756 test leads, add
100mΩ to ppm of range uncertainty.

15. Specifications are for external cable and load capacitance <1nF.
16. For offset compensation on, add 10ppm uncertainty to ppm of reading.
17. For 4-wire 1MΩ, open lead detector on, add 10 ppm uncertainty to ppm of reading.
18. Specified for <10% lead resistance mismatch in HI and LO.
19. Specifications are for 4-wire resistance, offset compensation on for ≤10kΩ measurements, and
offset compensation off for ≥10kΩ measurements. 1Ω range is 4-wire only. For 2-wire, with
