Marking Objects
Detected objects can be marked as required. The outer edges of an object
are indicated by the colour change of the signal LED 2 from yellow to red.
The centre of the metal object can be determined by the pitch. Using a
pen, mark the sought after location at the top and the side marker aids 1.
Continuous Flashing Green/Yellow/Red
If the signal LED 2 flashes alternately green, yellow and red, even when no
metal object or no "live" cable is in the vicinity, the measuring device must
be sent in for service.

Maintenance and Service

Manual Calibration

If the signal LED 2 illuminates red or yellow, even when no metal is in the
vicinity of the measuring tool, the tool must be recalibrated.
– To do this, switch the measuring device on using the On/Off switch 3.
– Remove a battery from the switched on measuring device.
– While the battery is removed, switch the measuring device off using
the On/Off switch 3.
– Reinsert the batteries into the measuring device (pay attention to the
polarity!)
– Now remove all objects in the vicinity of the measuring device (includ-
ing wrist watches or rings of metal) and hold the measuring tool up in
the air.
– Switch the measuring device on using the On/Off switch 3 and off again
within 3 seconds. The signal LED 2 of the measuring device will flash
red in slow succession during the 3 seconds to indicate that it is ready
to calibrate.
– Switch the measuring device back on within 0.5 seconds. The calibra-
tion is initiated and takes about 6 seconds. The signal LED 2 will flash
green for 6 seconds in quick succession, the calibration is being per-
formed. Now the device is once more ready for operation and the sig-
nal LED 2 illuminates solid green.
Note: If the sequence of switching off then on again is not followed, no cal-
ibration is performed. The signal LED 2 remains either yellow or red, even
though no metal is located within the vicinity. In this case, repeat the cal-
ibration.
