TROUBLESHOOTING
(1) Sampling processing
Measured temperature values that are measured every 320ms of sampling period are
stored in the buffer memory.
(2) 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 performed for a set period of time. Then, the total value, excluding
the maximum and the minimum values, is averaged and the averaged value is
stored in the buffer memory.
The number of processing times within the set period of time is calculated in the
following formula.
Number of processing times = set period of time 320 (times)
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, and 6, are conversion-enabled and the
average time is set to 2000ms, temperature is measured six times and the averaged
value is output.
2000 320 = 6.25 (times)...... Drop the fractional part
(b) Count average
Conversion is performed for a preset number of times. Then, the total value,
excluding the maximum and the minimum values, is averaged and the averaged
value is stored in the buffer memory.
The processing time is calculated in the following formula.
Processing time = preset 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, and 6, are conversion-enabled and the
average count is set to 5 times, the averaged value is output every 1600ms.
5 320 = 1600 (ms)
