(b) Warning clearance
After a warning occurrence, when the changed portion of the measured
temperature value falls lower than the rate alarm upper limit value or rises higher
than the rate alarm lower limit value, and returns to within the setting range, the
warning is cleared.
When the warning is cleared, "0" is stored in the bit position corresponding to the
channel of the warning output flag (rate alarm)(Un\G48).
The warning output signal (XD) turns OFF and the "ALM" LED turns off only when
the process alarm and rate alarm warings for all channels do not occur or are in
clearance state.

(c) Set the rate alarm upper limit/lower limit values in units of 0.1 for the measured
temperature range.
Setting range is -32768 to 32767 (-3276.8 to 3276.7 ).
Initial value is set to "0".
