Remote Interfaces
Warranty
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
DC Voltage Specifications
Maximum Input.............................................................1000 V on any range
Common Mode Rejection............................................140 dB at 50 or 60 Hz ±0.1 % (1 kΩ unbalance)
Normal Mode Rejection ..............................................60 dB for NPLC of 1 or greater with analog filter off and power line frequency ±0.1 %
Measurement Method..................................................Multi-ramp A/D
A/D Linearity .................................................................0.0002 % of measurement +0.0001 % of range
Input Bias Current ........................................................<30 pA at 25 °C
Autozero Off Operation ...............................................Following instrument warm-up at calibration temperature ±1 °C and less than 10
Analog Filter..................................................................When using the analog filter, specifications are relative to within one hour of using the
DC Ratio ..........................................................................Accuracy is +/- (Input accuracy + Reference accuracy), where Input accuracy = DC
Settling Considerations ..............................................Measurement settling times are affected by source impedance, cable dielectric
