6. Auto-tune.
Auto-tune is only needed if you want to use the PID mode in this meter. For
first-time users, or if the current control result is not good enough, users may
need to use auto-tune function to let the controller determine the parameters
automatically. If the auto tuning results are not satisfactory, you can manually
fine-tune the PID constants for improved performance. Or you can try to modify
the initial PID values and perform auto tune again. Sometimes the controller
will get the better parameters.
To start auto-tune, users need to set the At parameter for that specific channel
to 1. Please set the set point (SP) and hysteresis band (Hy) properly before the
auto-tune. During this process, the instrument executes the on-off control. After
2-3 times on-off action, the microprocessor in the instrument will analyze the
period, amplitude, waveform of the oscillation generated by the on-off control,
and calculate the optimal control parameter value. The instrument begins to
perform accurate artificial intelligence control after auto tuning is finished.
Generally, you will need to perform auto tuning once. After the auto tuning is
finished, the instrument will set parameter "At" to 0 automatically. This will
prevent an accidental repeat of the auto-tuning process.
Note:
1. If there is a power outage during the auto-tune, once power is resumed, the
auto-tune process will be resumed as well.
2. To exit the auto-tune, please change parameter At back to 0.
3. Auto-tune is only for one channel only. For optimize results, it is
recommended to run auto-tune for each channel separately.
