Please do not attempt to operate the equipment (e.g turn the knobs, push the buttons and etc.) if you do not understand how the equipment works.
4. Before connecting any circuit, please ensure suitable measuring/calibrating devices are connected to allow monitoring and adjustment from a safe distance.
