4 control system

The control system of this machine consists of an industrial computer, a highly integrated microcontroller, and a servo system. This control system is accurate, efficient, and highly integrated, using only oneRS232The serial port cable can complete the communication between the upper computer and the lower computer, achieving the purpose of precise detection. The operation is simple and convenient, and the micro ohm measurement module has been integrated into it, saving unnecessary expenses of purchasing a separate micro ohm testing machine.

9 Precautions

1Due to the load sensor（Load Cell）The axial force (including both pushing and pulling directions) exceeds the maximum load120%It will be damaged at times,

Please be particularly careful when operating. In addition, lateral and impact loads should also be avoided.

2This machine has a complete protection mechanism for the load sensor, but the prerequisite is that the load sensor connection wire must be securely connected. Besides,

Please use this machine under normal procedures, even if it moves at high speed and causes a hard collision, the load sensor can still be affected*

The protection.

3Due to the fact that this machine is usedWindowsSystem control, in order to avoid multitasking operationsCPUTemporary occupation of resources resulting in experimental closure

If there is any inaccuracy or misoperation, it is recommended to end other software programs when using this machine for testing. And screen saver program and power supply tube

Please also remove the logical part.

4It is recommended to assign a dedicated person to use this machine and the computer control part, especially to pay attention to the protection of computer viruses to avoid software damage

Functional errors and damage to experimental data.
