(3) Averaging processing
Averaging processing requires at least 2 times of conversion processing excluding the
maximum and the minimum values.
After the first averaging processing is completed, the corresponding bit for a channel
where processing has been completed of the Conversion completion flag (Un\G10)
turns ON (changes to "1").
(a) Time average
Conversion is executed for a period of set time, and the total value, which
excludes the maximum and the minimum values, is averaged and stored in the
buffer memory.
The number of processing times within the set time is below.
Number of processing times (times) = set time sampling period (320ms)
Setting range of time average is 1280 to 5000ms.
If a value outside the setting range is set, an error (error code: 20 ) occurs.
[Example]
When six channels, channels 1, 2, 3, 4, 5, 6, are enabled for conversion and the
set time is 2000ms, measurement is executed for six times and the average value
is output.
2000 320 =6.25 (times)...... Drop the fractional part
(b) Count average
Conversion is executed for a preset number of times, and the total value
excluding the maximum and the minimum values is averaged and stored in the
buffer memory.
The processing time is below.
Processing time = set count
320(ms)
Setting range of count average is 4 to 500 times.
If a value outside the setting range is set, an error (error code: 30 ) occurs.
[Example]
When six channels, channels 1, 2, 3, 4, 5, 6, are enabled for conversion and the
count averaging is set to 5 times, the average value is output for every 1600(ms).
