Setting up data for OFFSET correction

You can define a certain value and set it up as the data for OFFSET correction.
When the OFFSET correction is ON, taking the measured value before
correction as
measured value is corrected as
measurement result to your desired value, set up the difference between the
desired value and the measurement result as the data for the OFFSET
correction. For example, to correct the current measured value of the primary
parameter of 1.012 nF to the measured value of 1.000 nF, set up the data for
the OFFSET correction for the primary parameter to 12 pF.
The data for the OFFSET correction consists of 120 Hz, 1 kHz, and 1 MHz data
for both the primary and secondary parameters, as shown in
