4.8 Short Circuit Compensation
With short circuit compensation, it is possible to reduce the influence of the
residual impedance of the test cables and thereby to enhance the accuracy of
measurement. It is effective for test samples whose impedance is relatively low.
Short circuit compensation may be performed according to either of two methods:
ALL compensation
Compensation is performed at all the test frequencies.
SPOT compensation
Compensation is performed for one specified test frequency only.
 Before short circuit compensation, always set the cable length. For details,
refer to Section 4.14.
 The testing accuracy specified in the specification of the 3532-50 unit
assumes that open circuit compensation and short circuit compensation is
being performed, as appropriate.
 When you have changed the test cables, be sure to perform compensation
again. Correct test values will not be obtained if you go on testing using the
same old compensation values which were obtained before the cable change.
When performing compensation, make sure that there is no noise source
nearby. Noise may cause an error when performing compensation.
ex. Servo Motor, switching power source, high-voltage cable and etc.
Perform compensation in the state as close as possible to the actual one in
which the test sample will be measured.
The compensated value is preserved in the memory of the main unit even
when power is turned off.
Press the key.
Press the key.
Select the compensation method
(ALL compensation or SPOT compensation).
If setting has been completed normally, the short
circuit residual component and its phase angle are
displayed.
When compensation has been completed, press the
key to return to the Initial screen.
Short circuit compensation has been set.
