[1] The key specification here is the maximum source impedance. As long as your source impedance is not over this value, there will be no substantial errors due to impedance problems. For source impedance greater than this value, more settling time might be needed.
[2] 11V range characterized from -10 to +10 V.
[3] Tested using the 9.6V range.
[4] Tested using the 9.6V range running at 100 Hz.
[5] Calculated by connecting a 10 kΩ resistor between the positive and negative terminals then measuring the voltage across that resistor. Ohms law was then used to find the current through the resistor.
