Based on the set purity angle referred to as A, and the measured angle M, the auto
function assumes the following components:
Angle Component
-A ≤ M ≤ A pure resistance
90°-A ≤ M ≤ 90° pure inductance
A-90° ≤ M ≤ -90° pure capacitance
A < M < 90° resistance and inductance
-A < M < -90° resistance and capacitance
Serial/Parallel 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:
Impedance Equivalent circuit
0 ≤ Z ≤ S serial measurement
S < Z < range parallel measurement
8.6.2 Open/short/load correction settings
The correction dialog enables you to use the correction techniques provided by the
instrument.
Depending on the connected test fixture and the type of component sample to be mea-
sured, refer to the description on how to perform the corresponding corrections, see
Section 6.1, "About test fixtures", on page 53.
Access:
1. Press the [settings] key at the front panel.
2. Select the "Measurement" tab.

3. Select "Open/Short/Load Correction".
Figure 8-3: Open/Short/Load correction dialog
In this menu, you can enable the corresponding corrections directly, and access
the subdialogs to configure and start the corrections. You can save the correction
data of "Open/Short (FULL)" for later reuse.
The required remote commands are described in: Section 11.6, "CORRection sub-
system", on page 190
How to: see Section 8.6.3, "Performing open/short/load correction", on page 86.
If you need to perform the open and short correction frequently, you can assign these
functions to the [★ (User)] key and perform them with just one keystroke, see Sec-
tion 9.3, "User button", on page 127.

Figure 8-4: Start correction at one working point by the example of the short correction dialog
Performs the correction at a defined working point.
The function requires that you have enabled the state, see "Open/Short/Load Correc-
tion Enabled" on page 83, and set the test fixture to open, or short accordingly.

Figure 8-5: Start correction on all frequencies by the example of the open correction dialog
Performs the corresponding correction over the entire measurement range.
The function requires that you have enabled the state, see "Open/Short/Load Correc-
