In case an inclined rebar is displayed,
one has to find out the exact rebar di-
rection.
• For this purpose locate the rebar as
described below, but first remove the
probe from the cart.
• Once the MC
14
/
15
is above the re-
bar axis mark the position of the MC
on the surface at CL
16
at the upper
edge of the probe and on either side
of the MC.
• Position the CL point at the lower
edge of the probe precisely at the
marked center point.
• Turn the probe around this center
point until the maximum signal is
displayed. (Placing a set square with
one corner at the center point facili-
tates the turning of the probe).
The CL
16
runs parallel to and above
the rebar axis, when the signal strength
reaches the maximum and the MC
14
/
15
lights up.

Finding the rebar
direction
Whenever possible start with locating the rebars of the first layer, e. g. on
a column the horizontal stirrups.
• Holding the CL
16
horizontally, move vertically up or down until the
Arrow LED lights up and then move back until the MC LED lights up.
After having located the first layer rebars continue with locating the sec-
ond layer rebars.
• Position the MC
14
/
15
at the mid line of the first layer rebars, e. g.
on a column hold the probe with the CL running vertically and move
the probe cart vertically until both rectangles in the probe symbol are
green and of equal, minimum size.
• Now move the probe cart horizontally until one of the Arrow LEDs
17
lights up and then move back until MC LED
14
or
15
lights up.
• At this position you may also measure the diameter either by pushing
13
on the right side of the probe or
6
on the Touchscreen (e. g. when
the probe is fixed to the telescopic extension rod).
• If the spacing of parallel rebars is between 5 and 13 cm (2.00 to 5.20
inch), set the respective Neighboring Rebar Correction value first.
If the cover is too small for diameter measurement “too close” is displayed.
• In this case place a wooden or plastic board on the surface and set the
board thickness as Cover Offset to measure the diameter.
Finally the measured diameter must be set. The cover reading will be cor-
rected according to the diameter set.
NOTE! For more details about diameter measurement see
“3.7 Practical Hints”.
• Tap
7
to store the diameter and cover measurement.
• Repeat this procedure at each rebar.
The saved data can be seen in the Snapshot and Normal Statistics View
(see “3.6 Review of Data”).
NOTE! Cover values are only saved for later viewing, if the
diameter was measured and saved.
