An embodiment of the utility model discloses an impedance tap, impedance adjustment device, wherein, the impedance tap, dead ring and conducting ring including coaxial setting, be provided with first contact and at least one tie point on the dead ring, first contact with the conducting ring contact, be provided with the second contact on the conducting ring, control the conducting ring for the dead ring rotates, in order to incite somebody to action the 2nd contact connection extremely target tie point in the tie point. This adjusts the impedance tap, through the effective tie point of control with the 2nd male contact to preset the resistance value of electric wire netting and resistance value that short to ground is ordered is controlled to the access. From this, can be directly realize the control to inserting resistance value in the concrete circuit through the control to the impedance tap, and need not carry out artificial control to specific circuit that not only evaded the risk for operating personnel,
