(c) The rate alarm upper limit/lower limit values are set in units of 0.1 for the
measured temperature range.
Setting range is -32768 to 32767 (-3276.8 to 3276.7 ).
The default value is set to "0".
(d) The rate alarm warning detection period is set based on the number of conversion
periods.
Setting range is 1 to 6000 (times).
Calculation method of the rate alarm warning detection period is below.
(Rate alarm warning detection period)
= (Setting value of the Rate alarm warning detection period) (Conversion
period) (320ms)
[Example 1: When setting the rate alarm warning detection period to 150 times with
sampling processing]
Rate alarm warning detection period = 150 times 320ms = 48000ms = 48s
[Example 2: When setting the rate alarm warning detection period to 150 times with
averaging processing (count average: 10 times)]
Rate alarm warning detection period = 150 times 10 times 320ms = 480000ms =
480s
(e) Rate alarm is effective to monitor a change of measured temperature values
within a limited range.
