6.1productInstallation diagram

Please install the crack correctly according to the following diagramtransmitIncorrect installation of the device can lead to measurement errors and long-term damagetransmitEquipment;

6.2productinstallPrecautions

6.2.1transmitThe device is only suitable for indoor installation and not for outdoor use;

6.2.2 First, fix the stopper vertically to the wall, and thentransmitCompressor probe compression25mmFixed installation on both sides, so that the telescopic rod is in vertical contact with the blocking surface of the block grid；

6.2.3Installation requires ensuring that the limit surface of the installation bracket is perpendicular to the expansion rod of the crack gauge. Tilting can lead to inaccurate measurement data, reduced accuracy, and long-term damagetransmitInstruments, impacttransmitMeasurement accuracy of the instrument.

6.2.4transmitAfter the installation of the device is completedRead the initial data on the system platformvalueAnd set the zero point.
