Devote a tremendous amount of time, hot line job also there is very high danger, cost is high.
Resistance box, as conventional electronic machine, can be divided into the manual resistance box of knob and digital two kinds of resistance box.Wherein
The manual resistance box of knob carries out resistance setting by rotary knob to corresponding position, and its workload is larger and to a certain degree
On reduce work efficiency；The proportionate relationship of resistance and electric current typically realized by digital resistance case by operational amplifier, using control
Circuital current processed belongs to active regulation, is readily incorporated unrelated interruptions and error to change branch resistance resistance, this kind of mediation practices,
Therefore degree of regulation is limited and range is less, it is not suitable for accurate resistance and sets.Meanwhile because current resistance box cannot meet
The resistance of batch sets and resistance timing is changed, therefore makes its should be subject in some occasions needing multigroup resistance value contrast experiment
