CMU Calibration
The CMU calibration tab screen is used to perform the measurement data correction
of the multi frequency capacitance measurement unit (MFCMU). For the easy way,
perform the phase compensation and the open correction at least.
See also “Error Correction” on page 7-24.
NOTE For a more accurate measurement, perform correction data measurement at the
measurement frequency before starting the capacitance measurement.
If the measurement frequency is not included in the list of default frequencies below,
click the Advanced Options... button and set the measurement frequency on the
Frequency area of the Advanced Options for CMU Calibration window.
Default frequencies:
1 k, 2 k, 5 k, 10 k, 20 k, 50 k, 100 k, 200 k, 500 k, 1 M, 1.2 M, 1.5 M, 2 M, 2.5 M,
2.7 M, 3 M, 3.2 M, 3.5 M, 3.7 M, 4 M, 4.2 M, 4.5 M, 5 MHz
Measure... Opens a dialog box used to perform correction/compensation data measurement. To
perform the measurement, follow the dialog box.
The correction/compensation measurement data is saved and managed by the
workspace. And
the last measured correction/compensation data will be loaded
when the workspace will be opened next time.

This check box is effective after the phase compensation data is measured, and is
used to enable or disable the phase compensation. Uncheck this box to disable the
phase compensation.
To measure the compensation data, open the measurement
terminals at the end of
the device side and click the Measure... button.
If you extend the measurement cables to the device end by using
the four terminal
pairs method, do not forget to connect following terminals together at the device
end.
• the high potential (Hp) terminal and the high current (Hc) termin
al
• the low potential (Lp) terminal and the low current (Lc) terminal
