6.6.1.4
Place
the 0Ω (short) calibration standard on the test
head as prompted on the unit’s monitor and press Return on
the unit’s keyboard or ‘‘x1’’ on the unit.
6.6.1.5
Place
the 50Ω calibration standard on the test head
as prompted on the unit’s monitor and press Return on the
unit’s keyboard or ‘‘x1’’ on the unit.
6.6.1.6 Place
the HP 16453A test fixture or equivalent on
the test head as specified in accordance with the manufactur-
er’s instructions as prompted on the unit’s monitor.
6.6.1.7 Open
the fixture gap and lock it open as prompted
on the monitor and press Return on the unit’s keyboard or
‘‘x1’’ on the unit.
6.6.1.8
Short
the fixture gap as prompted on the monitor
and press Return on the unit’s keyboard or ‘‘x1’’ on the unit.
6.6.1.9
Place
the pure PTFE specimen in the fixture in close
contact with electrodes and with the PTFE specimen not
touching the back wall of the fixture, then press Return on the
unit’s keyboard or ‘‘x1’’ on the unit. Pull out the PTFE and
recheck. Permittivity should be within ± 0.01 or ± 0.02 units.
If not, recalibrate starting at ‘‘Fixture.’’ If it is still off, redo the
calibration from beginning.
6.6.1.10
Test
the sample in accordance with Section 5.
6.6.2
The
following calibration/test program is the latest ver-
sion of what was developed for the P H4291A. Using a text
editor (no embedded coding), enter this program on a DOS-
formatted disk and name it ‘‘AUTOST.’’ Place the disk in the
unit and turn it on (If you have any improvements PLEASE for-
ward them to the IPC): The program disk will calibrate and
configure the instrument’s screen. Two windows will appear.
The top window should be permittivity (E’r) and the bottom
window should be loss tangent (δ). Both windows should be
set to the frequency range entered in 6.3.1.2. If they are not,
return to 6.3.1 and repeat the process.
