Measuring data for SHORT correction
Execute measurement of the data for the SHORT correction. When the
measurement finishes successfully, the SHORT correction is automatically set

Setting up ON/OFF directly
Use the following procedure to set the SHORT correction to ON/OFF.
Step 1.
Press [Meas Setup].
Step 2.
Press the CORRECTION softkey.

If you change the setup of the cable length or frequency shift (1 MHz) with
the SHORT correction ON, the warning message "Need corr meas" appears
and the SHORT correction is automatically set to OFF. Along with SHORT
correction, OPEN and LOAD correction is set to OFF as well.
If you set the SHORT correction to ON using the above procedure when the
setup of the cable length or frequency shift differs from that during
measurement of the data for SHORT correction, the warning message
"Need short meas" appears. Even if this warning message appears, the
SHORT correction is set to ON. However, you must again measure the data
for SHORT correction to ensure accurate measurement.
When the measurement result becomes overload, "Measurement failed"
error is displayed and SHORT correction data is not updated.
