3. SETTING UP
3.1 Packing list
The standard packing of the instrument includes the following elements:
1. Instrument with display unit and measuring
insert holder
2. Measuring insert
3. Setting gauge
4. Charging unit
5. User’s manual
6. Calibration certificate
While unpacking, carry the instrument by lifting if by its displacement handle (8) and body.In
NO case should the instrument be carried by the handle for carriage displacement (3).
Keep the original packaging for future transportation.
If the instrument has been stored at a temperature below 5°C, wait a few hours before
unpacking to prevent the instrument parts from condensation. Condensation can affect
sensitive parts of the instrument.
750 50 0045 036

V3 / V4
3.2 Setting-up
After unpacking, prepare the instrument as follows:
1. Clean the pads positioned underneath the base using a
clean cloth, slightly dampened with alcohol.
2. Position the instrument with care on a clean measuring
plate.
3. Slide the measuring insert into the holder and lock it,
using the knob. Take care to position the eccentric
probes correctly.
4. Release the transport safety screw (chromium-plated).
Note:
Do not try to remove the screw (screw stop)!
5. 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 charging units 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 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 :
V5/V6: This procedure is carried out automatically in
motorized mode.
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 (§ 8).
.

750 50 0045 038

V3 / V4
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 (§ 8).
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.
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.

the upper profile as near as possible to the reversal
point (3). Engage the measuring force until the
acoustic signal. Move the instrument (or the part)
laterally to determine the reversal point (4).
Diameter and centreline values are displayed on
the 1st and 2nd lines of the display respectively.
3b. External diameter
Set the measuring insert off center on the lower
shaft profile as near as possible to the reversal
point (1). Engage the measuring force until the
acoustic signal. Move the instrument (or the part)
laterally to determine the reversal point (2). It is
automatically stored. Remove the measuring insert
slowly to the side, off center (3).

as near as possible to the reversal point (4).
Engage the measuring force until acoustic signal.
Move the instrument (or the part) laterally to
determine the reversal point (5). Remove the
measuring insert slowly to the side, off center (6).
Diameter and centreline values are displayed on
the 1st and 2nd lines of the display respectively.

5.4 References
5.4.1 Selection of references
The use of references allows a parallel measurement starting
from different points of origin (=references).
The current reference is mentioned at the top left hand side
of the display. For reference change, press reference key
and enter the reference number.
Note :
It is possible to choose the number of references (from 1 to
9). To configure the number of references, see § 8.
5.4.2 Assignment of a preset value to a reference
By pressing the Preset key, the previously entered preset
value for each selected reference will be taken into
consideration for height measurements, centerline distances
or Min / Max values.
In direct mode (see § 6.4), the preset is executed at the
current position of the probe.
A preset value can be assigned to each reference.
Select the required reference and press the
Preset
key
longer than 2 seconds. Enter the value and confirm by
pressing the
Validation key

5.6 Setting / memorizing of the probe constant
To check and memorize the probe constant, press the
following key and follow the same sequence as for "Setting
into operation" (§ 4.1, points 4 to 8).
Note 1:
The current constant value is shown on the second line of
the display by pressing this key once. A second pressure
interrupts the acquisition of constant and brings the
instrument back into height measuring mode.

5.7 Selection of the measuring unit
Measurements can be performed either in mm or in inch. To
change the unit, press the
mm/in
key. The active unit is
displayed below the probing indicator.
Note:
It is possible to lock in the required measuring unit (§ 8).
5.8 Measuring in Min / Max / Delta mode
Max = Measurement of maximum value ( )
Min = Measurement of minimum value ( )
Delta = Difference between Max and Min ( )
The measurements in mode Min, Max Delta have always to
be done with the probe being in contact with the surface.
It allows to determine the following values :
Min
: Minimum value of the measured surface
Max
: Maximum value of the measured surface
Delta
: Difference between the maximum and minimum
value
To select the Min, Max or Delta mode, press the key on the
keyboard. By pressing the same key several times, the
required mode will be displayed. To quit this mode, press

6. SECONDARY FUNCTIONS
6.1 Inversion of the measuring direction
It is possible to invert the measuring direction to obtain
positive measuring values in both directions (upwards and
downwards starting at zero). This function is mainly used
when the part to be measured is higher than the measuring
range of the instrument.
Press
+/-
key during 2 seconds to revert the direction of
measurement. The inversion indicator of the measurement
direction is mentioned as long as this mode remains active.
> 2 s
Preset
Immediately after having inverted the measuring direction,
the preset value of the active reference will be replaced by
the last measured value (height or centerline) before the
inversion.

Afterwards, the Preset value will be the initially entered one.
Procedure:
1. Perform measurements in a normal way
2. Turn the part when having reached the limit of the
instrument range
3. Invert the measuring direction
