Value in delta mode
DST Distance (when checking squareness)
INC Angle of inclination
MAX Value in Max mode
MIN Value in Min mode
PER Squareness value
POS Current position (no probing)
PRE Preset
REC Rectilinearity

ZERO Zero setting
10.3 Probing movement
The accuracy and repeatability of measurements depends on the contact quality of the measuring insert on
the part to be measured (
⇒probing on surface). The instrument embodies all necessary elements to
perform optimum measurement :
Probing indicator:
Located at the left side of the displayed measuring value, the
probing indicator controls the measuring insert position with
set measuring force. During a probing movement, the moving
line must stay between the 2 marks of the measuring zone
(green background). If the measuring zone will be exceeded,
the indicator background becomes red.
Acoustic signal
An acoustic signal confirms a correct measurement probing
movement (measuring force set) and that the value has been
stored in the buffer.
Measuring direction arrow
In addition to the acoustic signal, the measurement is
confirmed visually by a direction arrow (green LED)
Shock (motorized version)
If the measuring insert has been set with too high speed on a
profile or if the measuring zone has been passed (red
indication), a shock will be mentioned (text "Collision"). The
probe constant and the reference must be rechecked and the
measurement repeated.
10.4 Battery pack (operational lifetime, power capacity…)
Battery type: NiMH. They can be charged and discharged at least 500 times before their power capacity will
decrease. To optimise the operational lifetime of the battery pack and to allow them to obtain a maximum
power capacity, perform at least 5 complete charging cycles when using the instrument initially. Generally, it
is recommended to discharge the battery completely before charging again. Do not keep the instrument for
a too long period with an empty battery pack.
