Preparation for Accurate Measurement (Executing Correction)
Obtaining Correction Data
5-
Measurement procedure
Step 1. Connect the standard for the LOAD correction to the test fixture.
Step 2. Press [Meas Setup].
Step 3. Press the CORRECTION softkey to display the correction page.
Step 4. Use the cursor keys to select the LOAD field.
Step 5. Press the MEAS LOAD softkey. The data for the LOAD correction is then
measured.
• During the measurement, an “LOAD measurement in progress” message is
shown on the display.
• When the measurement has finished, the “LOAD measurement in progress”
message disappears.
• During the measurement, the ABORT softkey is shown. Use this key when
you want to abort load correction.
Step 6. When measurement of the data for LOAD correction is successfully completed,
the LOAD correction turns to ON.
If the difference between the measured value and definition value of the
standard for the LOAD correction exceeds 10% (not suitable for the data for
LOAD correction), the warning message “Out of limit” appears.
If a measurement failure occurs while measuring the data for correction, the
error message “Correction Meas Aborted” appears.
Step 7. Use the cursor keys to select the LOAD RNG field.
Step 8. Use the following softkeys:
Even if this warning message appears, data for the LOAD correction is still
used. However, it is recommended to confirm that the connection between
the test fixture and the UNKNOWN terminal as well as the measurement
procedure are correct.
If this error occurs, the data used for correction before the measurement
remains without change.
Softkey Function
AUTO Turns ON the auto-ranging function when load correction is executed.
FIX Turns OFF the auto-ranging function.
When the load range is set at FIX, the selected measurement range is used
at the LOAD measurement.
