An external PC used to control a hardness testing machine refers to a standard commercially available PC that meets all the technical requirements (interfaces, memory, processing power, etc.) for the hardness tester. The standard PC is loaded with a standard operating system (e.g. WIN 7, WIN 8), potentially other software packages as well as the operating software for the hardness testing machine.

External PCs are operated using standard input devices, such as a mouse and keyboard, and equipped with a standard monitor for display purposes.

External PCs are primarily used in conjunction with fully automatic hardness testing machines. This is due to the fact that a large number of very complex and laborious hardness testing functions need to be implemented, which require a high storage capacity and plenty of processing power.
