1. Access the Setup Mode.
2. Press the Page key until the display reads AutoTune. Press the key to enable
the AutoTune.
3. Press the Page key for three seconds to exit Setup Mode.
4. Cycle power to the instrument.
5. Set Manual Mode to run. The display will alternately display AutoTune and
Manual.
If the Manual Mode setpoint is less than 50 degrees higher than the actual process
temperature, the AutoTune function will create an error condition. This can be cleared
by either cooling off the process temperature or increasing the setpoint until there is
more than 50 degrees between them. Once the AutoTune function is allowed to
complete tuning, the AutoTune parameter will disable by itself.
If you wish to cancel the AutoTune function, press the STOP key, access the PID page
in Setup Mode, and set the AutoTune parameter to Disable.
