If required the backlight of the LCD can be switched on.
This can be done by pressing key ↑ for more than 2s.
RESET process
• Hold the probe in the air and press the START/RESET
key. A bar appears in the display that informs you on the
progress of the procedure. The probe shall not be moved
before the bar has disappeared and «0» is displayed.
• Please repeat this check procedure from time to time.
Locating the rebars and measuring the concrete cover
For locating the rebars, the diameter setting is not as
important as for measuring the cover.
In the case of double layer arrangements of
rebars, always start the location with the first
layer.
If the rebars of the first layer are too close to
each other, it is likely to be impossible to lo-
cate the bars of the second layer. See also
«Universal Probe», page 4.
• Move the probe from a starting position in one direc-
tion. Observe the locating aids: current concrete cover,
flow bar, (short) beep, variotone, signal value. As long
as the flow bar moves to the right, the probe is approa-
ching a rebar. If the flow bar stops moving, the probe is
directly over the rebar axis. If the centerline of the
probe has overshot the rebar axis somewhat, acoustic
and visual indication is given in the «beep» setting by a
short beep and by «—» in the «Current cover» display
field. At the same time, the flow bar moves to the left
and the cover is temporarily stored in the field Memo».
• When having activated the audible locating aid «Vario-
tone» («MENU»
→
«Basic Setups»
→
«Audible locating
aid»), the audio frequency increases as the probe
approaches a rebar. In this operation mode the cover
of the scanned rebar is also temporarily stored in the
field «Memo».
• In the case of loud noises from the surroundings, use
the headset to hear the acoustic signals.
