Preparation for Accurate Measurement (Executing Correction)
Executing OPEN/SHORT/LOAD Correction
NOTE
When you write correction data, note the following:
• Before writing, recall the settings of the measurement frequency, cable length, and
frequency shift (for 1 MHz) specified when the data was read.
• For the LOAD correction data, in addition to the above, you also need to recall the
settings of the LOAD correction standard (definition value and parameter type)
specified when the data was read.
• Turn ON the correction function. (Unlike when measuring the correction data, writing
the correction data does not automatically turn this function ON.)

Avoiding work-related mistakes in measuring correction data
To avoid simple mistakes related to work when measuring correction data (for example,
setting up the OPEN state and SHORT state inversely), it is important to confirm that the
measured data has a proper value.
If a measured value is not proper during measurement of the correction data, a warning
message appears on the display. However, the occurrence of a warning message cannot be
detected through GPIB/LAN/USB. Therefore, to detect erroneous correction data through
GPIB/LAN/USB, you need to read out the correction data after each measurement and then
confirm that the value is appropriate.
