Safety instructions
Please read first
This device has been developed for use in LD Didactic
experiments. If the device is used for other measure­
ments, the user is responsible for determining any haz­
ards and taking the necessary safety measures.
All users should be instructed about the dangers of elec­
tric current.
The user of the Databus detector must ensure compli­
ance with the guidelines of the employers' liability insur­
ance association or other insurance carriers, country-
specific specifications and specifications for schools and
universities.
Duty of this device is only permitted under expert super­
vision in a controlled electromagnetic environment of re­
search, teaching and training centres (schools, universi­
ties, institutes and laboratories).
Electrostatics or similar electromagnetic phenomena
(HF, burst, indirect lightning discharges, etc.) can per­
manently affect the device so that it no longer operates
within the specified Data (functional failure). After the in­
terference has subsided and the device has been
switched off and on again, the defined basic status is re­
stored.
