Disconnection state conversion setting function

(1) For values to be stored in the CH
to Un\G18) when disconection state is confirmed (corresponding bit of
the disconnection state monitor flag (Un\G49) turns to "1"), any of "Up
scale (the maximum value of measured temperature range +5% of
measured temperature range)", "Down scale (the minimum value of
measured temperature range -5% of measured temperature range)", or
"Given value" can be selected.
Setting is available for each channel.
(2) This function is effective for only conversion-enabled channels.
(3) When up scale (0
maximum value of measured temperature range +5% of measured
temperature range) or down scale value (the minimum value of
measured temperature range -5% of measured temperature range) of the
individual range is stored.

(4) When Given value(2
setting for disconnection state value (Un\G166 to Un\G173) in units of
0.1 .
The value set in the area is stored in the CH
value (Un\G11 to Un\G18) when disconnection state is confirmed.
(5) Confirming a disconnection state takes up to 11s.
During the period, the measured temperature value keeps dropping, and
the value changes to the conversion setting for disconnection state
value when disconnection state is confirmed.
(6) Obtaining a normal mearued temperature value after the recovery of
disconnection takes up to 11 seconds.
Temperature conversion restarts 11 seconds after the recovery of
disconnection, and normal measured temperture value is stored into
buffer memory. Then the conversion completion flag (Un\G10) turns to "1".
