3.2.2 Conversion setting for disconnection detection function
(1) For values to be stored in the CH measured temperature value (buffer memory
addresses 11 to 14, 54 to 61: Un\G11 to 14, Un\G54 to 61) in the case of
disconnection detection, any of "Value immediately before disconnection", "Up
scale (maximum value of measured temperature range + 5% of measured
temperature range)", "Down scale (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 can be utilized only for channels where temperature conversion is
enabled.
(3) When Up scale (1
H
) or Down scale (2
H
) is set, an Up scale value (maximum value
of measured temperature range + 5% of measured temperature range) or a Down
scale value (minimum value of measured temperature range – 5% of measured
temperature range) of the individual range is stored respectively.

(4) When Given value (3
H
) is selected, specify a value to CH conversion setting
value for disconnection detection (buffer memory addresses 150 to 157: Un\G150
to 157). When Given value(3H) is selected, set a value for the CH conversion
setting for disconnection detection (buffer memory addresses 150 to 153:
Un\G150 to 157) in units of 0.1 .
The value set in the area is stored in CH measured temperature value when
disconnection is detected.
