Electrical Specifications
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 %
100 dB for NPLC of 1 or greater with analog filter on 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 minutes, add error: 0.0002 % range additional error
+5 μV.
Analog Filter............................................................ When using the analog filter, specifications are relative to within one
hour of using the ZERO function for that range and NPLC setting.
DC Ratio ................................................................. Accuracy 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 Considerations........................................... Measurement settling times are affected by source impedance, cable
dielectric characteristics, and input signal changes.
