 Global LOAD correction procedure (When the value of the standard is not known)
To execute the correction in the range between the specified lower and upper limit frequencies,
perform the following steps to execute the LOAD correction.
 Disables the spot correction. Also, disables the LOAD correction.
 Execute the OPEN correction and the SHORT correction with a smallest additional error, and
then measure the LOAD standard value with the standard.
 Disables the OPEN correction and the SHORT correction.
 Connect the standard at the end of the actual connection circuit network and measure the LOAD
correction value.
 The LOAD correction is automatically enabled.
 Execute the OPEN correction and the SHORT correction again at the end of the actual
connection circuit network.
