4-WIRE OHMS (≤ 10 kΩ) OFFSET COMPENSATION ON
RMS NOISE (ADDITIONAL PEAK NOISE UNCERTAINTY)
29
 Applies to ± ppm of range
 Peak noise uncertainty is included in DC specifications for ≥ 1 PLC
 Add peak noise uncertainty to measurements for < 1 PLC
Examples
 1 kΩ at 0.006 PLC: 3 (from Accuracy table) + 26 (additional peak noise uncertainty) = 29 ppm of range

1 k
Ω
at 1 PLC: 3 + 0 = 3 ppm of range

Noise values are based on 1000 readings with autozero on and using low thermal 4-wire short. RMS noise is typical. Additional peak noise is
guaranteed.
