Setting spot LOAD correction
To execute the correction with only the current frequency, enable the spot correction.
The spot LOAD correction is set as follows.
_SHIFT_
+ [LOAD] >> LOAD correction menu
When the spot correction is enabled, "SPOT" is displayed.

OFF Disables the spot correction.
At the correction value measurement, global correction values are measured.
At the standard value measurement, global standard values are measured.
At the DUT measurement, the global correction value and the global standard value
are used.
ON Enables the spot correction.
At the correction value measurement, the spot correction value at the current
measurement frequency is measured.
At the standard value measurement, the spot standard value at the current
measurement frequency is measured.
At the DUT measurement, the spot correction value and the spot standard value are
used only when the measurement frequency is same as the spot LOAD correction
frequency. Otherwise the global correction value and the global standard value are
used.
Format Displays the format setting menu for LOAD correction.
STD Displays the spot LOAD standard value input menu.
Entry Displays the spot LOAD correction value input menu.
If a setting is made or the EXIT operation is performed, one-previous menu comes back.
Whether the spot correction is enabled or disabled is common to the OPEN, SHORT, and LOAD
corrections.
If the measurement frequency is changed when the spot correction is enabled, the OPEN, SHORT,
and LOAD corrections are all disabled automatically. When you want to execute the spot correction
with a new frequency, measure the correction value again. When recalling from the setting memory,
the OPEN, SHORT, and LOAD corrections are not disabled even if the frequency is changed due to
the operation, and the saved settings are restored. Even if the frequency is automatically changed by
