[ 1 ] Resolution is defined as the typical 10 VDC range RMS noise.
[ 2 ] Normal mode rejection for power–line frequency ± 0.1%.
[ 3 ] Maximum rate for DCV, DCI, and 2–Wire resistance functions
[ 4 ] Autozero on for => 1 NPLC.
[ 5 ] For power–line frequency ± 1% 75 dB and for ± 3% 55 dB.
[ 6 ] Only for 34411A /L4411A.
Transfer Accuracy (Typical)
All DC volts, <0.12 A DC Current, < 1.2 M : (24 hour % of range error) / 2)
All other DC current and resistance: (24 hour % of range error + % of reading)/2

(using zero settling delay, autozero off, etc.).
Basic dc accuracy specifications (previous page) include RMS noise at 100 NPLC.
For <100 NPLC, add appropriate "RMS Noise Adder" to basic accuracy specification.
- Within 10 minutes and ±0.5 °C
- Within ±10% of initial value.
- Following a 2–hour warm–up.
- Fixed range.
- Using 10 NPLC.
- Measurements are made using accepted metrology practices.
