RMS NOISE (additional peak noise uncertainty)
42
• 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:
• 1mA at 0.006 PLC: 9 (from Accuracy table) + 20 (additional peak noise uncertainty) = 29 ppm of range.
• 1mA at 1 PLC: 9 +0 = 9 ppm of range.

42. Noise values are based on 1000 readings with autozero on and AMPS terminal open. RMS
noise is typical. Additional peak noise is guaranteed.
43. Rear input terminals only.
44. With line sync on.
45. Values are typical and guaranteed by design.

±5°C; specifications without autocalibration.
47. For 3-wire RTD, accuracy is for <0.1Ω lead resistance mismatch for input HI and LO. Add
0.25°C/0.1Ω of HI-LO lead resistance mismatch.
48. Exclusive of cold-junction errors.
