5 Initial start-up
5.1 Preparing the instrument for use
Before switching on the instrument, proceed as follows:
1. Check whether the power supply of the instrument supplies the correct input
voltage.(198 - 253 VAC, 50/60 Hz).
2. Check if the mains voltage selector switch of the PC is set to the proper input
voltage (230V/115V).
3. Check the filling level of the gas-washing bottle. Fill with water if required, see
page 45.
4. Set the argon pressure to 4.8 - 5.0 bar (69.6 - 72.5 psi).
If the argon pressure is not properly set, turbulences result in the spark
stand insert. Thus, correct measuring results cannot be obtained.
The instrument is ready for use.
