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

3.3. General description of the instrument
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
Distance measurement with dimensions
Setting of measuring reference
Setting of timer for measurements
Connection to Bluetooth devices, iPhone, iPad,
iPod touch, Android via Meterbox APP
Activation of the laser pointer for measurement
Integrated air bubble level
Partial operations with use of internal memory (max
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.

4.2. Setting of measuring reference
In order to perform correct measurements, it is
important to define beforehand the measuring
reference on the instrument by pressing the key.
Possible options are:
Top measurement is carried out by the upper
part of the instrument.
Bottom measurement is carried out by the lower
part of the instrument and therefore also the whole
instrument length is considered (default condition)
“Bottom” reference “Top” reference
