Performing Fixture Compensation
In order to perform more accurate measurements, before beginning the measurement
procedure, it is necessary to compensate the fixture. For the 16196A/B/C/D, perform
measurements of the data for open compensation and of the data for short compensation.
NOTE The 16196A/B/C/D requires frequent wear checks to keep the best measurement accuracy.
When the equipment is used for the first time following purchase or part replacement,
“Wear Check” should be conducted. Refer to “Wear Check” on page 44 for details.
NOTE If there are temperature fluctuations which exceed a temperature range of
±
5
°
C after
fixture compensation has been carried out, then perform fixture compensation again.
Measuring Open Compensation Data
Set the fixture in the open state using the open plate supplied.
Step 1. Remove the cap.
CAUTION Make sure there is no dirt or other foreign matter in the DUT insertion hole.
Step 2. Using the Tweezers, place the open plate on top of the insulator assembly. Set the open
plate with the protruding surface down.
CAUTION Handle the open plate with Tweezers. If dirt, etc. gets on it, measuring precision and
repeatability may be adversely affected.
