Step 3. Use the cursor key to select [OPEN] field
Soft key Function
ON Enables open correction.
OFF Disables open correction.
MEAS OPEN Starts open correction.
Step 4. Press [MEAS OPEN] soft key, a dialog message display “Connect the UNKNOWN
terminal with no DUT”.
Step 5. Please Connect the UNKNOW terminal and test fixture with no DUT connected.
Step 6. Press [OK] soft key. The AT281x measures open admittances (capacitance and
conductance) at the all test frequency points.
During the measurement, an “OPEN measurement in progress” dialog message is shown
on the display.
When the measurement has finished, a message “ Correction finished” is displayed.
During the measurement, you can press [ABORT] soft key to abort open correction.
Step 7. Press the ON key to enable open correction in successive measurements.
5.2.2 ShortCorrection[SHORT]
The short correction feature of the AT281x compensates for any residual impedances
(R,X) that may exist within the interval from the calibration plane, which is determined
by the
selected cable length, to the DUT connecting points (see Figure 5-4)

Step 4. Press [MEAS SHORT] soft key, a dialog message display “Short-circuit the test
terminals”.
Step 5.
Connect the UNKNOWN terminal and the test fixture and short-circuit test terminals
Step 6. Press [OK] soft key. The AT281x measures short impedances (inductances and
resistance) at the all test frequency points.
During the measurement, an “SHORT measurement in progress” dialog message is
shown on the display.
