Assembling Check
Short Plate Check
Measuring the fixture’s impedance with the short plate in place should check the condition
of the short plate.
CAUTION
“Short Plate Check” should be performed after the “Electrode Check” has been completed.
Required Tools
•
1.5-mm hex wrench (provided accessory)
•
Impedance measuring instrument (with 7-mm connector and calibrated)
NOTE
To make the same settings as given in the above table, refer to the Operation Manual for
the measuring instrument.
Procedure
Step 1.
Clean the short plate as described in “Cleaning” on page 41.
Step 2.
Remove the cap and place the short plate with the protruding surface down on the insulator
assembly.
Step 3.
Place the cap on the fixture body and fasten it.
Step 4.
Measure Rs and Ls at 100 MHz and 1 GHz in this condition.
Step 5.
Confirm that the Rs and Ls values are within the representative values given in the table
below. If the results are outside the limit range, please replace the short plate.
