Measurement Averaging; Introduction; Moving Average - MICRO-EPSILON capaNCDT 6200 Operating Instructions Manual

Operation
5.5
5.5.1
Measurement averaging is performed before the output of measuring values via the Ethernet interfaces.
Measurement averaging improves the resolution, allows masking individual interference points or "smoothes"
the reading.
i
The controller is delivered ex factory without measurement averaging.
5.5.2
The definable number N for successive measurements (window width) is used to calculate the arithmetic
average M
M
Fig. 22 Formula for the moving average
Method
Each new measured value is added, and the first (oldest) value is removed from the averaging.
Example with N = 7:
.... 0 1 2 3 4 5 6 7 8
.... 1 2 3 4 5 6 7 8 9

Measurement Averaging

Introduction

Linearity is not affected by averaging. Averaging has no effect on measuring frequency and output rate.

Moving Average

according to the following formula:

MV = Measuring value
N = Number
k = Continuous index
M = Average value
