Preventing Mistakes During Execution of Calibration and
Compensation
Setting limit values for the DC resistance (Rdc) measurement value when calibration and
compensation are executed makes it possible to detect an improperly attached standard
during calibration or any abnormality with the measurement terminals during
compensation.
1. Setting the limit for DC resistance (Rdc)
Step 1. Press the [Cal/Compen] key on the front panel to display the Cal/Compen softkey menu.
Step 2. Press the SETUP CAL WIZARD key in the softkey menu to display the
Calibration/Compensation Wizard Setting dialog box (
Figure 6-23).

Step 3. The following settings should be made in the Calibration/Compensation Wizard Setting
dialog box:
•In the Calibration area, select the calibration to be performed in addition to
Open/Short/Load calibration.
•In the Compensation area, select the compensation to be executed.
• For the measurement point table range for which calibration and compensation should
be performed, select either
Active table only or Calibrate all tables.
• Select the test fixture to be used from the Fixture area.
• To automatically store the setting conditions of the 4287A and the calibration and
compensation data in the “autorec.sta” file upon completion of the
calibration/compensation, click the
Auto Recall check box so that the check mark (√)
appears.
Step 4. Click the Rdc Limit Check check box in the Calibration/Compensation Wizard Setting
dialog box so that the check mark (
√) appears, thus turning on the DC resistance (Rdc)
limit check when calibration and compensation is performed (
Figure 6-24).
