E1412A Datasheet, PDF (4/11 Pages) Agilent(Hewlett-Packard) – 6.5-Digit High-Accuracy Multimeter C-Size

DC Specifications (continued)
Specifications are for 1-hour warm-up at an integration time of 100 PLCs.
DC:DC Ratio:
Measurement method:
Input HI-LO/Reference HI-LO
Apply “Reference HI-LO” signal to Ohms 4-Wire Sense terminals.
Input HI to Input LO:
100 mV to 300 V
Reference HI to Input LO: <12 V on 100 mV to 10 V ranges (autoranged)
Reference LO to Input LO: <2 V
Additional Error with Autozero OFF:
Following instrument warm-up at calibration temperature ± 1°C and <10 minutes.
100 mV-100 V ranges:
300 V range:
add 0.0002% reading + 5 µV
add 0.0006% reading
DC Operating Characteristics: Readings speeds for 60 Hz and (50 Hz) operation, Autozero OFF.

*For 300 V range: use 0.003% of range for 5.5 digits and 0.030% of range for 4.5 digits.
For all ranges: add 20 µV for dc Volts, 4 µA for dc current, or 20 mΩ for resistance.

Considerations
Settling considerations:

Measurement considerations:


Reading settling times are affected by source impedance, cable
dielectric characteristics, and input signal changes.
Agilent recommends the use of PTFE (Polytetrafluoroethylene) or
other high impedance, low-dielectric absorption wire insulation for
these measurements.
