Electrical Specifications
DC Voltage 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.

When using the analog filter, specifications are relative
to within one hour of using the ZERO function for that
range and NPLC setting
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)
Measurement settling times are affected by source
impedance, cable dielectric characteristics, and input
