ORDERING INFORMATION
• Code number: JDL-A[1][2]-[3][4]
Specify a code from below for each of [1] through [4].
(e.g. JDL-A1A-B/Q)
• Special output range (For codes Z & 0)
Default setting (following table) will be used if not otherwise
specified.
No linearization data will be programmed if you don't
specify type of linearization and required data.
• Linearization data
Code 1 segment data: Use Ordering Information Sheet (No.
ESU-1669) to specify linearization data.
Code 3 T/C, Code 4 RTD: Specify input sensor type and
temperature range.
