5.6 Operation example of load correction
5.6.1 Operation steps
Assume that the test conditions used by the user are as follows:
Frequency: 100kHz. Cp standard value: 11nF D standard value: 0.0005
Press [Cal], the instrument will display the <User Corr> page.
Move the cursor to Load, the following soft keys will be displayed in the soft key zone: ON and
OFF.
Press ON to turn on the load correction function.
Move the cursor to Load Type, Ls-Rs, Ls-Q, Cp-D, will be displayed in the soft key area on the
right side of the screen.
Press Cp-D to select the Cp-D function.
Move the cursor to Freq zone, the following soft keys will be displayed in the soft key zone: ON,
OFF, OPEN, SHORT and LOAD.
Press ON to turn on the point-frequency correction function of the corresponding FREQ in current
correction point.
Input the correction frequency (100k), reference A (11nF), reference B (0.0005)
Move the cursor to FREQ. The following soft keys will be displayed: ON, OFF, OPEN, SHORT
and LOAD.
Hold the test fixture be in open status and keep user’s hands or other interference source be far away
from the test fixture. Press the soft key OPEN to execute open correction.
Insert the short plate (TH26010) into the test fixture. Please ensure that the short plate and the reeds
of the test fixture have good contact.
Press the soft key SHORT to execute short correction.
Insert a standard capacitance into the test fixture. Please ensure that the pins of the standard
capacitance have good connection with the reeds of the test fixture.
Press the soft key LOAD to execute load correction.
5.6.2 Note
a) Because of the different software editions, the soft keys and status information may be
different form this book, but it may not affect users’ understanding.
b) The load correction is only valid for the components with the same specification. If the
specification is changed, it is required to redo load correction.
