Operation
optoNCDT 1700
6.6 Average Setting
The optoNCDT1700 is supplied ex factory with the default setting „moving averaging, number of averaging
N = 1“ (no averaging activated).
Averaging methods: The purpose of averaging is to:
- Moving average - Improve the resolution
- Recursive average - Eliminate signal spikes
- Median - „Smooth out“ the signal.
Averaging has no effect on linearity.
6.6.1 Averaging Number N
In every measurement cycle (at a measurement frequency of 2.5 kHz every 0.4 ms) the internal average is
calculated anew. The averaging number N indicates the number of consecutive measurement values to be
averaged in the sensor.
Averaging type Averaging number LED „avg“ In setup mode the averaging number can be set to
4 different, predefined fixed values. Further details
on these, see Chap. 6.5. The selected averaging
number is also indicated in measurement mode by
the “avg“ LED, see Fig. 21.
Averaging does not affect the measurement fre-
quency or data rates in digital measurement value
output.
More averaging counts can also be used if pro-
grammed via the digital interface, see Chap. 8.5.4.

The averaging is recommended for static measurements or slowly changing measuring values.
IMPORTANT!
The preset average
value and the number
of averaging are
saved after switching
off.
