The present invention relates to a power-on test tooling which belongs to the measurement electrical variable device field, limits a sliding distance of a meter holder on a tooling panel accurately, and simplifies a connection structure between the meter holder and the tooling panel. The power-on test tooling comprises the inclined tooling panel, the meter holder is arranged on the tooling panel, and the upper end of the meter holder is equipped with a contact pin parallel with the tooling panel. The tooling panel is equipped with a guide groove and a locking groove communicated with the guide groove, a stepped hole is arranged on the meter holder, and a limiting rod is arranged in the stepped hole. When one end of the limiting rod corresponds to the guide groove, the other end of the limiting rod extends out of the meter holder. The stepped hole comprises a large diameter segment, and an elastic element is arranged at the large diameter segment of the stepped hole transversely. One end of the elastic element abuts against the hole wall of the stepped hole, and the other end abuts against the limiting rod. When one end of the limiting rod corresponds to the locking groove, the elastic element pushes the limiting rod to slide transversely along the locking groove.
