[1] Continuously variable from 0 to 330 MΩ.
[2] Applies for COMP OFF (to the 5500A Calibrator front panel NORMAL terminals) and 2-wire and 4-wire
compensation.
[3] The floor adder is improved to 0.006 Ω (0 to 10.99 Ω range) and 0.010 Ω (11 to 329.999 Ω) if the 5500A
Calibrator is zeroed (ohms zero or instrument zero) within 8 hours and temperature is +1°C of zeroing
ambient temperature.
[4] Do not exceed the largest current for each range. For currents lower than shown, the floor adder increases

. For example, a 100 µA stimulus measuring 100 Ω has a floor uncertainty
of 0.01 Ω x 1 mA/100 µA = 0.1 Ω.

[1] This is for the largest resistance for each range. The maximum voltage for other values is Imax (highest
value of Allowable Current above) multiplied by Rout.
[2] Maximum lead resistance for no additional error in 2-wire COMP.
