Getting Started
Learning Basic Measurement Procedure
Step 6. When measurement of the data for OPEN correction is successfully completed,
the OPEN correction turns to ON (as shown in Figure 3-9).

Description of softkeys
To enable/disable or otherwise control the behavior of open correction, use the
following softkeys:
If open admittance |Yo| (= ) is greater than 20 µS (an unsuitable level for the
data used in OPEN correction), the warning message “Out of limit” appears on the
System message area on the screen.
If a measurement failure occurs while measuring the data for correction, the
error message “OPEN Measurement incomplete” occurs.
Softkey Description
ON Enables open correction.
OFF Disables open correction.
MEAS OPEN Starts open correction.

Even if this warning message appears, the data for OPEN correction is still
used. However, you should recheck the connection between the test fixture
and the UNKNOWN terminal and confirm that the OPEN correction
procedure was done correctly.
If this error occurs, the data for correction before the measurement remains
without change.
