3. PREPARATION FOR USE
3.1. INITIAL CHECKS
Before shipment, the instrument’s electronics and mechanics have been carefully checked.
All possible precautions have been taken in order for the instrument to be delivered in
optimum conditions. However, we recommend rapidly checking the instrument in order to
detect possible damage occurred during transport. Should you detect anomalies, please
immediately contact the dealer.
It is also recommended to check that the package contains all parts indicated in § 12.5. In
case of discrepancies, please contact the dealer. Should it be necessary to return the
instrument, please follow the instructions given in § 13.
3.2. INSTRUMENT POWER SUPPLY
The instrument is battery supplied. For battery type and life, see § 12.3.
The symbol "
" indicates the charge level. When there are five bars next to the
battery symbol, it means that batteries are fully charged; a decrease in the number of bars
to "
" indicates that the batteries are almost low. In this case, interrupt tests and
replace the batteries according to the indications given in § 11.2.
The instrument is able to keep data stored also with no batteries.
For the insertion of batteries, follow the indications given in § 11.2.
The instrument is provided with advanced algorithms to maximize the batteries’ life. In
particular:
 the instrument automatically turns off the display’s back lighting after ca. 5 seconds.
 in order to increase battery autonomy, should the voltage supplied by batteries be too
low, the instrument disables the display’s back-lighting function.
3.3. CALIBRATION
The instrument’s technical specifications are those described in this manual. Its
performance is warranted for one year from the date of purchase.
3.4. STORAGE
In order to guarantee precise measures, after the instrument has remained stored for a
