Open/Short/Load Correction
Accesses the dialog for activating the correction functions, see Chapter 8.6.2, "Open/
short/load correction settings" , on page 78.
Auto Function
Opens the dialog for configuring the auto function parameters.
During the measurement, the auto function refers to the purity angle that is set in the
instrument, and the measured value. Concerning the separation point, the function
determines the equivalent circuit based on the estimated absolute value of Z.

Purity Angle ← Auto Function
Sets the switching point of the phase angle.
Based on the set purity angle referred to as A, and the measured angle M, the auto
function assumes the following components:

Serial/Paralell Separation Point ← Auto Function
Sets the threshold for the function to switch from serial to parallel impedance measure-
ment, according to the equivalent circuit.
Based on the set separation point S, and the measured impedance Z, the auto function
assumes the following equivalent circuits:
