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.
