Turning ON/OFF Correction Functions

Turning on LOAD correction

Use one of the following two ways to set the LOAD correction to ON.
Measuring LOAD correction data
Execute measurement of the data for the LOAD correction. When the
measurement finishes successfully, the LOAD correction is automatically set to
ON. For information about the measurement procedure for the data used in the
LOAD correction, refer to
page
Setting up ON/OFF directly
Use the following procedure to set the LOAD correction to ON/OFF.
Step 1. Press [Meas Setup].
Step 2. Press the CORRECTION softkey.
Step 3. Use the cursor keys to select the LOAD field.
Step 4. Press the ON softkey to turn ON the LOAD correction function.
If you change the setup of the cable length or frequency shift (1 MHz) with
the LOAD correction ON, the warning message "Need corr meas" appears
and the LOAD correction is automatically set to OFF. Along with LOAD
correction, OPEN and SHORT correction is set to OFF as well.
If you set up the LOAD 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 LOAD correction, the warning message "Need
load meas" appears. Even if this warning message appears, the LOAD
correction is set to ON. However, you must again measure the data for the
LOAD correction to ensure accurate measurement.
When the measurement result becomes overload, "Measurement failed"
error is displayed and LOAD correction data is not updated.
