Characteristics
☆ Multiple output\adjustment methods
"Direct output" mode: the value output can be set directly by physical key or touch screen.
Calibration of the analog pointer meter usually needs to test scale by scale, especially "differences between rising and falling" (the change caused by the rise and fall of the calibration point).
Remote box can realize the coarse and fine adjustment of current or voltage.
