5.6.REINITIALISING THE INSTRUMENT

To reinitialise all the test parameters, please follow the procedure below:
1. Switch off the instrument by setting the ON/OFF key to the OFF position.
2. Press the SET UP key and keep it pressed while switching on the instrument.
Machine Tester followed by Hard Reset are displayed for a few moments, then the main menu opens.
NOTES : The reinitialised values of the adjustable parameters correspond to the requirements of standard EN 60204.
