Accuracy specifications are valid for 6½ digit resolution mode after at least a 1 hour warm-up with Auto Zero enabled.
24-hour specifications are relative to calibration standards and assume a controlled electromagnetic environment per EN 61326-1:2000-11.

Common Mode Rejection140dB at 50 or 60Hz ±0.1% (1kΩ unbalance)
Normal Mode Rejection60dB for NPLC of 1 or greater with analog filter off and power line frequency ±0.1%
100dB for NPLC of 1 or greater with analog filter on and power line frequency ±0.1%
Measurement MethodMultiramp A/D
A/D Linearity0.0002% of measurement + 0.0001% of range
Input Bias Current
Auto-zero Off OperationFollowing instrument warm-up at calibration temperature ±1℃ and less than 10 minutes, add error: 0.0002% range additional error +5μV.
Analog FilterWhen using the analog filter, specifications are relative to within one hour of using the ZERO function for that range and NPLC setting.
DC RatioAccuracy is ±(Input accuracy + Reference accuracy), where Input accuracy = DC Voltage accuracy for the HI to LO Input (in ppm of the Input voltage), and Reference accuracy = DC Voltage accuracy for the HI to LO (Sense) Reference (in ppm of the Reference voltage).
Settling ConsiderationsMeasurement settling times are affected by source impedance, cable dielectric characteristics, and input signal changes

*15 Typical measurement rates with auto-zero off, delay = 0, display off, auto range off and math off.
*16 Maximum measurement rates for 0.01% of AC step. When DC input varies, additional settling delay is required.
*17 For remote operation or external trigger using default settling delay.
*18 Speeds available in OutG SW 1.0.700.18 or higher. Note that the measurement rates for RS232 can vary depending on the baud rate chosen. If the baud rate selected is 115,200, the maximum measurement rate is 711 measurements. The LAN bus has a maximum measurement rate of 963 measurements.
