26 Keysight 16452A Liquid Test Fixture

Operation

Checking the SHORT Residual

Before using the test fixture, you should check its electrical performance. You

can confirm its performance by checking the SHORT residual. The SHORT

residual must be measured with the compensation function OFF because the

compensation cancels the SHORT residual.

Procedure

1. Set the compensation function OFF (OPEN, SHORT and LOAD, depend on

your measurement instrument).

2. Select the measurement parameter "Ls-Rs"

3. Check the SHORT residual value at 1MHz is in the following range:

For the measurement setting, please refer to your measurement instrument.

If the SHORT Residual is Out of Range

1. Check the connection of the test fixture and the measurement cable. Also,

check the shorting plate connection.

• Is the spacer width in the 16452A 1.3mm?

• Does the shorting plate contact to both high and low electrodes?

• Are the electrodes clean and free from rust?

2. If the problem cannot be corrected, please contact the nearest Keysight

Technologies sales office.
