Applies for 4-WIRE compensation only. For 2-WIRE and 2-WIRE COMP, add 5 μV per Amp of stimulus current to the floor
[2]
specification. For example, in 2-WIRE mode, at 1 kΩ   t he floor specification within 12 hours of an ohms zero cal for a measurement
current of 1 mA is:
0.002 Ω  5 μV / 1 mA = (0.022 + 0.005) Ω =  0 .007 Ω.
For currents lower than shown, the floor adder increases by Floor(new) = Floor(old) x Imin/Iactual. For example, a 50 μA stimulus
[3]
measuring 100 Ω has a floor specification of: 0.0014 Ω x 1 mA/50 μA = 0.028 Ω assuming an ohms zero calibration within
12 hours.
