Setting of spot correction (common to OPEN correction and SHORT correction)
When the zero correction is made with current frequency only, set the spot correction to ON.
If the measurement is executed with specific frequency only, the measurement time of
correction value is short and an error of correction value, which occurs by interpolation in
other than direct correction value frequency, will not occur. The spot correction of DC
resistance is not supported.
First, press the
_ SHIFT _ + [OPEN]
keys to display the OPEN correction menu, and select
SPOT with the

The correction value is measured in a range from the specified lower limit
frequency to the maximum frequency.
The spot correction value is not used for correction.

Enables the spot correction.
The correction value is measured with current measurement frequency only.
The spot correction value is used for correction if the measurement
