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.

Advanced

tions...

Opens

the “Advanced Options for CMU Calibration (page 4-39)” dialog box used to

set the frequencies for the correction data measurement and the referenc

e values of

the working standard.

Phase

mpensati

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

• the low potential (Lp) terminal and the low current (Lc) terminal
