frequency point and the standard reference value to eliminate other test errors. It can be seen that
open circuit, short circuit and load correction can be performed at the set frequency point. Before
setting the standard reference value, the reference value must be set in the reference value
corresponding field. When the cursor moves to Freq or Ref, the screen displays the soft key Load.
Press the Load key to perform a load correction test on the standard.
Load correction function switch option:
Invalidate the load calibration test data under the
current set frequency.
Make the load calibration test data valid at the
current set frequency.
3.8.4 Load type
When performing load correction, the reference value of the standard device must be input in
advance.
The test parameters of the reference value should be consistent with the set load correction test
function. The load correction function uses the transfer coefficient between the actual test value at
the set frequency point and the standard reference value to eliminate other test errors. The load
correction test function is only used to calculate the transfer coefficient.
This series categorizes the load types into 3 categories:
3.8.5 Cable
The cable length currently available is 0 m and 1 m.
The factory default is 0m calibration.
3.8.6 Point frequency operation
Follow the steps below to perform an open/short/load correction test on the set frequency point.
Move the cursor to the frequency setting area. The screen will display the following soft keys.
Invalidate the open/short/load calibration test data at the
current set frequency.
Make the open/short/load correction test data valid under
the current set frequency, and the frequency setting field
displays the originally set open/short/load correction
frequency.
Perform a open correction test on the current frequency
