To maintain accuracy, it is recommended to calibrate the 9240si annually. Use a certified mV/mA source to verify that the controller's displayed value matches the injected signal. Clean the front face with a dry cloth; avoid harsh chemicals that could damage the display overlay.

Terminals for TC/RTD are usually located at the bottom row. Ensure polarity for thermocouples is correct (Red is typically negative in US standards).

Modifies values, changes setpoints, or toggles configuration choices. Access Levels

Displays the target setpoint value in green LEDs.

It is recommended to calibrate the input every 12 months to maintain precision. The may have specific I/O: S for serial
