RMS NOISE (ADDITIONAL PEAK NOISE UNCERTAINTY)
7
 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
 Input impedance set to auto
Examples:
 10 V at 0.006 PLC: 1.2 (from Accuracy table) + 11 (additional peak noise uncertainty) = 12.2 ppm of range

10 V at 1 PLC: 1.2 + 0 = 1.2 ppm of range
