    • The invention relates to a test device, by means of which power poles are tested for hardness or rot depth. The device comprises a frame portion and a test needle or corresponding member located therein or thereto. The test needle is to be exposed to an actuation force so as to penetrate into the pole material. The degree of penetration for a definite actuation force is a measure of the hardness or rot depth. The test device further comprises means to be exposed to actuations, for example manual ones, by which means the actuation force to the penetration portion can be produced. The frame portion is provided with a part, which entirely or partially can be driven into the ground base adjacent the pole. The exposed means extend with upper portions above the ground surface in order to permit actuations to produce the actuation force. At the upper portions of the exposed means indicating means are located which indicate the degree of penetration for a definite size of the actuation force.
    • 本发明涉及一种测试装置,通过该测试装置测试电源极的硬度或腐蚀深度。 该装置包括框架部分和位于其中或其上的测试针或对应的构件。 测试针被暴露于致动力以便穿透到极材料中。 确定的致动力的穿透度是硬度或腐蚀深度的度量。 测试装置还包括暴露于例如手动的致动装置,通过该装置可以产生对穿透部分的致动力。 框架部分设置有一部分,其完全或部分地可以驱动到邻近极的接地基座中。 暴露的装置在地面上方的上部延伸,以允许致动产生致动力。 在暴露的装置指示装置的上部定位有指示致动力的确定尺寸的穿透程度。
