Statistical Calculation
1. Function
1. This function calculates the maximum value, minimum value, average value,
standard deviation, and range of the measurement data that is stored in the mea-
surement memory.
2. The following calculations are performed at the same time in the statistical cal-
culation.
• Number of samples
S
CNT
=(Number of data) - (Number of overload),
in the specified range
• Maximum value

MAX
=Maximum value of the data to be calculated
• Minimum value

3. All measurement data except for overload (OL) and calculation error data can be
used for the calculation.
2. Performing the calculation
1. Select STAT in
