5. Slide the measuring insert into the holder and lock
it, using the knob. Take care to position the
eccentric probes correctly.
6. Release the transport safety screw.
7. Check / adjust the floating probe suspension
balancing (§ 10.3).
8. If the instrument does not switch on or in
case of low battery level, proceed to a full
loading of the batteries (plug in the charging
unit to the instrument). Empty batteries are
fully loaded in about 3 hours.
Only use the charging unit supplied with the instrument to load the batteries.
It is not necessary to wait until the battery pack is fully charged. The instrument
becomes operational immediately after having connected the charging unit.
It is not dangerous to leave the charging unit connected. Permanently plugged-in
instruments automatically switch to trickle charge mode.
The batteries are of Lithium-ion type. An excessive room temperature can affect
the battery capacity and therefore the instrument autonomy. It is not
recommended to load the battery in case of room temperature superior to 40C°.
Incorrect loading of the battery can result in a decrease of capacity, overheating,
or even an explosion and cause important damages.
The battery can be loaded and unloaded 300 times before a significant reduction
of their capacity. The number of loading cycles and the autonomy can vary
according to use and operating conditions.

4. GETTING STARTED
4.1 Displacement Modes : Manual/Motorized
4.1.1 Manual Displacement Mode
V3, V4 & V8
The manual displacement of the carriage is carried out with
the help of the handle. This is the only possible
displacement mode for V3 & V4. The V8 has a fine
adjustment.
V5 & V6
Push the handle inwards in order to pass into manual
mode. In manual mode, V5 & V6 are used in the same way
as V3 & V4.
4.1.2 Motorized Displacement Mode (V5 & V6)
Pull the handle outwards to work in motorized mode. In this
mode, the rotating handle can be tucked inside for
ergonomic reasons.
The motorized displacement is carried out with the 2
buttons situated behind the handle. For other motorized
displacement methods, see § 10.4.
Rapid Displacement
A prolonged pression on one of the buttons causes a rapid
movement in the chosen direction. The carriage will
continue its displacement as long as the pressure is
maintained.
Slow Displacement (Probing)
A short pressure causes a continuous displacement in
probing speed, i.e. speed used for measuring. As soon as
the probe gets in touch with a surface, a measurement is
made.
Release of Probe
When the probe is in contact with the part (after probing),
a short pressure on the button for the opposite direction
allows to release the probe (ca. 0.5 mm).
Movement Stop
While displacing in low speed mode, a short pressure on
the button for the same direction as that of the
displacement will stop the movement.

4.2 Setting into Operation
1. Switch on the instrument by pressing button
On/Off during 2 seconds. All segments of the
display will light up.
Switch off the instrument by pressing the same
button until the instrument turns off.
> 2 s
2. The display will ask for the reference position.
Move the measuring carriage slowly across the
mark indicating the reference position with the
help of the handle for carriage displacement (the
acquisition of reference is carried out by
displacing the carriage upwards). An acoustic
signal will confirm that the reference has been
detected and the display starts counting. If the
display does not start counting, repeat the
sequence.
Note :
This procedure is automatically carried out in
motorized mode (V5 & V6). The probe will
position itself at the same level as the reference
gauge (see below).
3. The instrument is now asking for the probe
constant. This function compensates the
dimension and the deflexion of the measuring
insert when probing downwards and upwards
(reversed surfaces, diameters). The last stored
probe constant value will be displayed.
Note 1 :
This procedure may be interrupted by pressing on
the probe constant key or on the
Validation key
.
The latest probe constant value measured is then
recorded.
Note 2 :
The start mode can differ, according to the
instrument configuration (§ 9).
or

4. Use the setting gauge supplied with the
instrument to carry out this operation.
Note:
A different setting gauge may be used. In this
case, its dimension must be configured in the set-
up menu (§ 9).
5. Move the measuring insert downwards (use the
handwheel for the displacement of the measuring
carriage) until it touches the surface and an
acoustic signal confirms the measurement
(=probing).
6. Without moving any part (instrument and gauge),
move the measuring insert towards the top and
perform the same sequence on the upper surface
of the setting gauge.
7. Repeat the sequences 5 and 6 one more time.
This allows establishing the probe constant more
precisely.
2x
8. The screen will display the setting gauge value
during the latest probing, as well as that of the
new probe constant. The instrument is then ready
to be used.
In motorized mode (V5 & V6) this procedure can be
automatically carried out by pressing the key opposite
The probe constant needs to be checked and stored again after each measuring
insert change, after change of its position in the holder, after each adjustment of
the measuring force or adjustment of the floating probe suspension.
