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 AA LR06
batteries, included in the package. Battery life equals
about 8000 measurements. The “
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

iDM70 has the following functions:
Direct measurement of distances expressed in
m/in/ft and ft+in
Measurement of area and volume
Indirect 2- and 3-point distance measurement
(Pitagora)
Distance measurement in continuous mode
Sum/difference of measured distance values
Measurement of tilt angle

20 locations)
Display backlight
Activation of buzzer upon key pressing
The model is provided with a wide display, a
comfortable membrane keyboard with 13 function keys
and a class II laser pointer for a precise definition of
the application point.
The measurement of distance between two points
(with a measuring range from 5cm to 70m) is carried
out by reflection of the laser light from the surface hit
to the receiving sensor located in the upper part of the
instrument.
Measurement can be influenced by the brightness of
the environment in which it is performed and by the
type of surface hit by the laser pointer.

5. MEASURING CONDITIONS
Measuring range
The instrument's measuring range is 70m. At night,
under poor visibility conditions or if the surface to be
measured is in shadow, the measuring range can be
reduced. To prevent this, carry out measurements
during the day or use luminous plates when the object
to be measured has poor reflecting properties.
Object surface
The instrument can give errors when measurements
are carried out on colourless liquids (e.g. water),
transparent glass, polystyrene, very polished or halfpermeable surfaces because of the deviation of the
laser beam. Non-reflecting surfaces may cause delays
when measuring.
Maintenance
Do not immerse the instrument in water. To clean the
instrument, use a soft cloth moist with neutral
detergent
6. REPLACING INTERNAL BATTERIES
The instrument is supplied by 2x1.5V AA LR06 alkaline
batteries. When the symbol “
display, it is necessary to replace the batteries.
Proceed as follows:
1. Slide the battery compartment cover to the right and
remove it (see Fig. 14)
2. Remove the batteries and insert the same number
of batteries of the same type, respecting the correct
polarity. Only use alkaline batteries
3. Restore the battery compartment cover into position
by sliding it to the left to fasten it again
