Make sure to prepare before installation of the material tester

Material testing machineAs a precision instrument, there are many things to pay attention to during installation. If you are not careful, it will affect the measurement accuracy of the test machine. The following is an introduction to the steps before using and installing the material test machine:

(1) Water concrete with a strength level of not less than C20 in the pit, and leave holes for anchoring anchor screws and pipelines for installing circuits and sensors when pouring the concrete. Leveling of planes of concrete foundations is applied.

(2) Dig a hole downward to the installation position of the test machine, the size is greater than 50cm longer and wider than the base of the test machine, and the depth is not less than 30cm.

(3)Testing machineIt should be installed in a room that is clean, dry, without vibration and can be controlled at (10-35)℃. In addition, there should be enough space in the room to ensure that there is more than 70cm space around the test machine for testing and daily maintenance.

(4) The test machine is connected to a three-phase and four-wire power supply, and the power supply should be equipped with an air switch and a leakage protection device. The wires should be greater than 150 cm away from the ground, and a manual switch should be installed on the wires to control the power supply of the test machine.
