2. PREPARATION FOR USE
2.1. Initial checks
Before shipping, the instrument has been checked
from an electric as well as mechanical point of view.
All possible precautions have been taken so that it is
delivered undamaged.
However, we recommend generally checking the
instrument in order to detect possible damage suffered
during transport. In case anomalies are found,
immediately contact the forwarding agent.
We also recommend checking that the packaging
contains all components indicated in § 9. In case of
discrepancy, please contact the Dealer.
In case the instrument should be returned, please
follow the instructions given in § 10.1
2.2. Instrument power supply
The instrument is supplied with two 1.5V AAA LR03
batteries, included in the package. Battery life equals
about 5000 measurements. The “
“ symbol
flashes on the display when the battery is flat. Replace
the battery by following the instructions given in § 6
2.3. Storage
In order to guarantee precise measurement, after a
long storage time under extreme environmental
conditions, wait for the instrument to come back to
normal condition (see § 8.1). Given its simplicity, the
instrument does not need any periodic calibration.
