Notes
5. Specifications are for 2- and 4-wire resistance. For 2-wire, use relative offset and add 100 mΩ of additional uncertainty. For 4-wire, turn offset compensation on for ≤10 kΩ and off for
>10 k Ω. The 1 Ω range is for 4-wire only.
6. Requires a 10-reading digital filter at 1 PLC or 2-reading digital filter at 5 PLC.
7. Specified for < 10% lead-resistance mismatch at HI and LO.
8. Applies for 1 Ω through 1 MΩ ranges. For 100 Ω range, multiply the listed values by five. Noise values apply to terminals using a low-thermal short for 50 Hz and 60 Hz operation only.
Measurements through a card may introduce additional noise.
9. Open lead detection off.
10. Line sync on.
