The operation panel includes LCD monitor, rotary encoder and five function buttons.
Main off-line operation:
Parameters are set by rotary encoder. The items can be switched by rotary encoder. Under a
certain item, press the encoder, then rotate it. It can increase or decrease the values or switch into
other items. Integrated with the soft keyboard, some special setting functions can also be set. After
setting, press the encoder again, it restores into the original status. The rotary encoder and five
function buttons can be used with combination in which it can switch the unit, set the parameters
and output.
