MODEL: JDL–A[1][2]–[3][4]

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.

• Specify the specification for option code /Q

(e.g. /C01/S01)
