    100mm GRAPHICS RECORDER TECHNICAL MANUAL STATIC ELECTRICITY High voltages (tens of kilo-volts) can be generated on the human skin through a number of mechanisms, such as fric- tion between different materials (e.g. nylon and skin), and separation of similar materials (e.g. masking tape, nylon sheet).
  • Page 8 100mm GRAPHICS RECORDER TECHNICAL MANUAL Safety Notes 1. Whenever it is likely that protection has been impaired, the unit shall be made inoperative and secured against unintended operation. The nearest manufacturer’s service centre should be consulted for advice. 2. Any adjustment, maintenance and repair of the opened apparatus under voltage, should be avoided as far as possi- ble and, if inevitable, shall be carried out only by a skilled person who is aware of the hazard involved.
