description The utility model belongs to the field of detection devices, particularly a railway signal detecting table device. The utility model is characterized in that a table head (2) is arranged at the upper part of the casing of the table and an indication disk (3) for measuring gear is arranged at the lower part; the upper center of the indication disk (3) for measuring gear is wound with a fault-detecting gear (5), a direct current voltage gear (7), an alternating current voltage gear (8), an electric current gear (6), an ohm gear (4), a resistor-trimming button (9), an electric current jack (10), a positive electrode jack (11) and a negative electrode jack (12). The utility model has the advantages of simple structure, low cost, high speed, accuracy, high safety, convenient operation, flexibility and convenient carrying.
