The utility model discloses a theodolite testboard, including body (1), support (5), base (6), elevating gear (7), testboard (8) and nine collimator (4), elevating gear fixes in one side of base, and the opposite side in base (6) is fixed through support (5) in testboard (8), the top at elevating gear is placed to the theodolite, five horizontal symmetries of collimator are fixed on the testboard, and the body is fixed at the middle part of testboard, sets up a collimator on the base under the testboard center, along vertically being equipped with three collimator and with the collimator at testboard center and set up collimator on the base in the coplanar on the body. The utility model discloses can through reforming transform, can satisfy the requirement of existing national metrological verification rules on the basis of not damaging original optics theodolite testboard infrastructure, have the effect that the transformation technique is simple, can practice thrift the measurement cost.
