5.4.3
Averaging timekount (addresses 2 to
5)
Addresses 2 to
5
are used to set the length of time or the number of times of
averaging.
(1) When the power is turned ON, the averaging time and averaging
count
are set to 0.
(2) The setting ranges are as indicated below:
Averaging processing in terms
of time
: 160 to 32000 msec
Averaging processing in terms of count
:
1
to 800 times
CAUTION
If a value outside the above range has been written, a setting error occurs
and the buffer memory is rewritten.
However, the A64RDC performs conversion processing at the averaging
time or count previously set.
5.4.4
Detected temperature value (addresses
6
to 17)
Addresses 6 to
17
are used to store detected temperature values which are
handled in 16-bit or 32-bit data.
(1)
16-bit data (addresses
6
to
9)
A detected temperature value is multiplied by 10 and represented in the
range from -1
800
to 6000 of 16-bit signed binary numbers.
If a detected temperature value is negative, it is represented
in 2's
complement.
Example 1:
If a detected temperature value
is 123.025"C (253.445"F), 1230 is
stored.
