Statistical Calculation
1. Function
1. This function calculates the maximum value, minimum value, average value,
standard deviation, and dispersion of the measured data that is stored in the mea-
surement memory.
2. For a statistical calculation, the following calculations are performed at the same
time:
• Number of samples
S
CNT
= (Amount of data) - (Amount of overload), in the
specified range
• Maximum value
S
MAX
= Maximum value of data to be calculated
• Minimum value
S
MIN
= Minimum value of data to be calculated
• Average value
S
AVE
=
• Dispersion
S
PTP
= | S

3. All measured data except for overload (OL) and calculation error data can be
used for the calculation.
2. Performing the calculation
1. Select STAT in
.
2. Select STAT and press
to perform the calculation.
If data does not exist in the measurement data memory, ‘LAST’ is displayed.
3. How to call the calculation result
1. The calculation result is displayed by selecting STAT in
.
2. After performing the statistical calculation, select an item to be displayed by
pressing
