DMM7512 Dual Channel 7½-Digit Sampling Multimeter
RMS Noise (additional peak noise uncertainty)
33
Applies to ± ppm of range.
Peak noise uncertainty is included in DC specifications for ≥1 PLC.
Add peak noise uncertainty to measurements when <1 PLC.
Examples 1 mA at 0.006 PLC: 9 (from Accuracy table) + 20 (additional peak noise uncertainty) = 29 ppm of range.
1 mA at 1 PLC: 9 +0 = 9 ppm of range.

NOTES
33. Noise values are based on 1000 readings with autozero on and AMPS terminal open. RMS noise is typical. Additional peak noise is guaranteed.
34. With line sync on.
35. Values are typical and guaranteed by design.
36. Add per degree from T
CAL
±5 °C; specifications without autocalibration.
37. For 3-wire RTD, accuracy is for < 0.1 Ω lead resistance mismatch for input HI and LO. Add 0.25 °C/ 0.1 Ω of HI-LO lead resistance mismatch.
