2.0 Transport and Storage
Please keep the original packaging for later transport, e.g. for calibration. Any transport
damage due to faulty packaging will be excluded from warranty claims.
In order to avoid instrument damage, it is advised to remove batteries when not using the
instrument over a certain time period. However, should the instrument be contaminated
by leaking battery cells, you are kindly requested to return it to the factory for cleaning
and inspection.
Instruments must be stored in dry and closed areas. In the case of an instrument being
transported in extreme temperatures, a recovery time of at least 2 hours is required prior
to instrument operation.
3.0 Operator´s
Safety
The respective accident prevention regulations established by the professional
associations for electrical systems and equipment must be strictly met at all times.
In order to avoid electrical shock, the relevant safety and VDE regulations concerning
excessive contact voltages must be strictly observed, especially when working with
voltages exceeding 120V (60V) DC or 50V (25V)rms AC. The values in brackets are
valid for limited ranges (for example in medicine and agriculture).
