Switching on the instrument

After transporting, wait at least 4 hours before turning the instrument on. This waiting
period is necessary to allow the compressor oil, which may have been displaced during
transport, to return to its original position. Failure to comply with this may cause damage
to the instrument.
• Switch the instrument on at the circuit breaker. The instrument is now initialized.
• The instrument is factory-configured as follows:
• Program the desired values as described under 6.2.1 to 6.2.3.
In normal operation, a pressure compensation shortly before the compressor starts up
might lead to a hissing sound.
