- Page 10 In Pulse mode, set the process values where the proportional pulse will start and where it will reach the maximum rate. Be sure to modify this setting if you change the Cond. Units. In Pulse mode, set the maximum rate for the proportional Pulse output. The CDTX-90 will accept any value from 0 to 400.

Page 16: Calibration Procedure
Calibration Procedure Requirements The CDTX-90 Transmitter is factory calibrated using simulated input signals. System calibration will reduce errors caused by sensor wire lengths longer than the standard 15 ft. length. Wire lengths of 100 feet are acceptable; cable shield must be maintained through cable splice. -
Page 17: Troubleshooting
If a Current Loop is locked at 3.6 mA, the problem is related to the temperature circuit: This occurs only if the CDTX-90 detects a resistance from the temperature sensor that is less than 250Ω or greater than 2800Ω. •... - Page 18 Notes page 18...
