3. PREPARATION FOR USE

3.1. 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 the instrument is delivered
undamaged. However, we recommend rapidly checking it to detect any damage possibly
suffered during transport. In case anomalies are found, immediately contact the dealer We
also recommend checking that the packaging contains all components indicated in § 7.4 In
case of discrepancy, please contact the dealer. In case the instrument should be returned,
please follow the instructions given in § 7.

3.2.

INSTRUMENT POWER SUPPLY

The instrument is supplied by alkaline batteries (see § 7.2.2). When batteries are flat, the
flat battery symbol “

” appears on the display. Replace/insert the batteries by following

the instructions given in § 6.2.

3.3. 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 conditions (see §
7.3).
