This ATRCT101 is an accurate press-button switch resistance and capacitance box. The features listed above make it a very useful and convenient tool for tuning analog circuits where changing capacitance and resistance is needed. In electronic circuit experiments, ATRCT101 can be used to provide accurate resistance and capacitance values, reducing the time to replace resistors or capacitors, thus greatly improving the time efficiency of tuning circuits. Its small size not only saves lab space, but also can be easily transported to another site. The anti-interference ability of this ATRCT101 is also better than other resistance and capacitance boxes in the market.
