[1] Continuously variable from 0 Ω to 1.1 GΩ.
[2] Applies for 4-WIRE compensation only. For 2-WIRE and 2-WIRE COMP, add 5 μV per amp of stimulus current to the floor
specification. For example, in 2-WIRE mode, at 1 kΩ the 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 = (0.002 + 0.005) Ω = 0.007 Ω.

. For example, a 50 μA stimulus 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.
