CP TD1
CP TD1 - 4
CP TD1
By connecting a reference capacitor (e.g., optional device
CP CAL1
) with known values of
capacity Cref and dissipation factor DFref, in mode UST-A the values Cx and DFx can be
measured and then compared to the known reference values.
If you experience substantial deviations, re-calibrate the
CP TD1
:
•
Cx = Cref / Cmeas and
•
DF / PF + = DFref - DFmeas
as described on page CP TD1-6.
A re-calibration of the
CP TD1
is also shown in the test report (
.xml
file).
Note:
If you change the factory-made calibration, the responsibility for the accuracy of the
CP TD1
will be in your hands.
Calibration tips:
►
For calibration, set the averaging factor to maximum and the filter bandwidth to ± 5 Hz (refer
to page CP TD1-5).
►
To reset to the factory settings, select "DF/PF+" to 0.0 ppm and "Cx" to 1.000 (refer to page
CP TD1-6).
Use the optional device
TH 3631
to measure ambient temperature, the test object temperature
and humidity. Once these values were measured, enter them into the respective entry fields of
the
TanDelta
test card’s
Settings
page at “Compensations” (see page CP TD1-6).
For detailed information on the
CP TD1
applications, refer to the CP TD1 Reference Manual
delivered with the
CP TD1
or available in pdf format on the
CPC 100 Start Page
.
