Tripping of a protective circuit
After a protective circuit (fuse) has been tripped, attempt to eliminate
the cause of malfunctioning (e.g. replace a defective valve) before
reactivating the protective circuit. Frequent tripping is usually due to
power overload which, in certain circumstances, may also damage
the instrument.
Malfunctioning/Repairing a defective instrument
The repair of a defective instrument – irrespective of the warranty
period – is only possible when the instrument is dismantled and
returned to us with a description of the error. Furthermore, please
inform us of the indicator type being used and the measured medium.
Before you return the instrument for repair work, remove the bottle
and ensure that the measuring chamber has been flushed out and is
empty.
