92 Keysight E4981A 120 Hz/1 kHz/1 MHz Capacitance Meter
Preparation for Accurate Measurement (Executing Correction)
Overview of Correction Function
5-
As shown in the data processing flow of Figure 5-1, the OPEN/SHORT/LOAD
correction is first performed for the measured impedance result (complex
number), and the result is converted to the primary/secondary parameters.
Then, for the primary/secondary parameter values (real number), the OFFSET
correction is performed.
Figure 5-1 Data processing flow
OFFSET correction
Corrects errors between the actual measured value and the ideal
value that the user desires. This is done by subtracting any value
that the user enters from the measured result (for example,
difference between a known standard value and its measured
value, or instrument-by-instrument differences in the measured
values of the same DUT).
Type of correction Description
In Option 002, there is no correction for 1 MHz frequency.
The measurement value displayed for correction or LOAD REF uses the
internal data for calculation. The value is set depending upon the state of
MULTI CORRECTION, LOAD REF, or CHANNEL.
