Page 7: Calibration System
The TFT32 has a simple 2-key calibration system. Operating and calibration modes are shown on the 4 digit display. The keys are used to calibrate the TFT32, and to view operating mode and functions. If the keys are not used for 10 minutes, the TFT32 will automatically go to NORMAL MODE. Except in OUTPUT SIMULATION mode, the Relay and RS485 serial output are not affected by use of the keys until your calibration is stored. -
