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.
Characteristic
Description
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
Multiramp A/D
A/D Linearity
0.0002% of measurement + 0.0001% of range
Input Bias Current
<30 pA at 25 °C
Auto-zero 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

Description

Measurement Method
Flexible counting technique. AC-coupled input using the AC voltage measurement function
Settling Considerations
When measuring frequency or period after a DC offset voltage change, errors may occur. For the most accurate measurement, wait up to 1 second for the input blocking capacitor to settle
Measurement Considerations
To minimize measurement errors, shield inputs from external noise when measuring low-voltage, low-frequency signals

13 Typical measurement rates with auto-zero off, delay = 0, display off, auto range off and math off.
14 Maximum measurement rates for 0.01% of AC step. When DC input varies, additional settling delay is required.
15 For remote operation or external trigger using default settling delay.
16 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
