*1: When used with BARD Intrinsic Safety Barrier, minimum span is 30 _C. When it is used with Pt100, in addition, the maximum span is 650 _C.
*2: Total resistance must be from 100 Ω to 2 kΩ. Span must be at least 50 % of total resistance.
*3: The maximum 10 Ω or a span _0.4, whichever is lesser par wire. When used with BARD Intrinsic Safety Barrier, the BARD internal resistance is not included.
*4: It is possible to select up/down/off by a switch for burnout. Burnout detection time is within 60 seconds. *5: Burnout is set “off” when it is shipped. Connected to BRAIN Terminal, it is possible to change a setting for burnout after shipment. Burnout detection time is within 60 seconds.
*6: The accuracy is a value for primary output. Accuracy rating of secondary output: _0.2 % (deviation from No.1 output). *7: When CT5 or CR5 is used with BARD Intrinsic Safety Barrier, output signals may be out of specified accuracy. Adjust span and zero with BARD Intrinsic Safety Barrier.
*8: There is a range whose Linearizer error exceeds _0.2 %. Please see the section under STANDARD RANGE LIST. *9: For Type B, there is no reference junction compensation.
*10: Connected it to B and C terminals of signal conditioner.
