*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.

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