8. Operation and Use
8.1 Stud Detector
2 Fig.
(B)
Place the detector at against the wall. Press and hold
button (B) to calibrate the unit. The buzzer will sound to
conrm and the display will read ‘Stud’.
Important: If by chance, the calibration is carried out
too close or over a stud the detector will not pick up a
reading and will give false information. For this reason it
is advisable to take a couple of readings and calibrate
the unit in dierent positions to ensure accuracy.
Upon detection of a stud or nogging the bars will begin
to increase on the LCD display and the buzzer will sound
when all twelve bars are lit.
The best method of accuracy is to mark the wall at the
point where the buzzer sounds. Then move the detector
approximately 30cm past this point. Trace back with the
detector again, until the buzzer sounds. Mark the wall,
and the midway point between the marks is the centre of
the stud/nogging.
Important: The wall must be a cavity design for the
detector to work correctly. If the cavity has been lled
with glass bre, even this may eect the readout.
8.2 Distance Detection
3 Fig.
Ensure the detector is positioned and pointing
perpendicular to the target area. The laser is a guide to
where the measurement is being taken.
The target area must be a rigid surface without any
irregularities. The target cannot be impaired by
obstacles.
For more accurate results and when measuring longer
distances ensure the target area is large (measurements
over 12M the target should be >3M2). For small and
irregular surfaces try axing a piece of board as the
target area.
The ultrasonic distance detection will not measure
through glass, but WILL measure to glass.
Measure from base (i.e. measurement includes length of
detector). Press button (C) to select metric or imperial
results.
TO TAKE STANDARD MEASUREMENTS:
• Press button (D) to take the measurement.
• The result will be displayed unless an error has
occurred in which case try again.
