CH1 Adjustment sensitivity (dead band) setting
To prevent chattering of the transistor output in the two-position control, set the adjustment sensitivity (dead band) for the set
value (SV).

■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory area name
CH Adjustment sensitivity (dead band) setting
CH Adjustment sensitivity (dead band) setting (in the Q compatible mode)
■Setting range
• In the R mode
0 to the full scale of the input range (())
• In the Q compatible mode
Set a value within the range of 1 to 100 (0.1 to 10.0%) to the full scale of the input range set in 'CH1 Input range' (Un\G501).
Ex.
When the following values have been set in the buffer memory areas:
• 'CH1 Input range' (Un\G501): 38 (Temperature measuring range: -200.0 to 400.0)
• 'CH1 Adjustment sensitivity (dead band) setting' (Un\G46): 10 (1.0%)
(Full scale)  (Adjustment sensitivity (dead band) setting) = (400.0 - (-200.0))  0.01 = 6.0
The dead band is the set value (SV) 3.0.
■Default value
• In the R mode
For the R60TCTRT2TT2 and the R60TCTRT2TT2BW, the default value is 5 (5).
For the R60TCRT4 and the R60TCRT4BW, the default value is 5 (0.5).
• In the Q compatible mode
The default value is 5 (0.5%).
