3. PREPARING THE INSTRUMENT
3.1. INITIAL CHECK
This instrument has been checked before shipment from an electrical and mechanical
point of view. All possible precautions have been taken in order to deliver it in perfect
condition. Notwithstanding, on receipt of the instrument we suggest that you check it
summarily to make sure that no damage has occurred in transit. Should you find
irregularities please contact the carrier immediately. Furthermore, please make sure that
the parcel contains all the accessories and parts listed in paragraph 13.3. In case of
discrepancies please contact your dealer. Should it be necessary to return the instrument
to the supplier please keep to the instructions given at paragraph 17.
3.2.
INSTRUMENT POWER SUPPLY
The instrument can be powered by:
 6 batteries 1.5V AA - LR6 series located in the compartment on the back of the
instrument
 an external power supply code DMT-EXTPS supplied with the instrument (standard
accessory).
CAUTION
For recordings ALWAYS use the external power supply (even though the
instrument allows the operator to perform a recording using internal
batteries).
The instrument uses sophisticated algorithms to prolong the battery life. Particularly:
 The instrument switches OFF the backlight Automatically after 5 seconds.
 If the instrument is displaying in real time (and the external power supply is not
connected), after about 5 minutes from the last key pressure or switch rotation the
instrument turns off automatically ("AUTOPOWER OFF" procedure).
 If the instrument is recording or is measuring energy (and the external power supply is
not connected), after about 5 minutes from the last key pressure or switch rotation the
instrument starts a special procedure to save the batteries ("ECONOMY MODE"): the
instrument keeps recording but the display is turned off.
3.3. CALIBRATION
The instrument complies with the standards mentioned in this manual. Its performance is
guaranteed for one year from the purchase date.
3.4.
STORAGE
To guarantee accurate measurements, after a long storage period in severe environmental
conditions wait until the instrument resumes its normal conditions (see environmental
conditions listed in paragraph 13.2).
