Statistics
This Function can perform some basic statistical analysis
without the use of SPC data collection on a PC or other
device. The Statistics Function can provide the following information:
1. Measurement Count.
2. Minimum Measurement.
3. Maximum Measurement.
4. Average Measurement in two modes:
a. Standard average (Measurement Sum ÷ Count)
b.
Trimmed average ((Measurement Sum - Max - Min) ÷ (Count - 2))
=
4
to enable this function.
F3 & F4
