Depth Measurement
This multi frequency locator can measure the depth of the target pipeline. Most
commonly used methods are direct reading, 80% and 45 degrees methods.
(1)
Direct reading method
: to measure the depth of the range: 4.5cm-6m. When the
range is exceeded or the signal is not normal, the receiver display shows an error
message.Before depth detecting, the target pipeline should be accurately located by
the receiver peak mode and the valley mode. If the two positions are inconsistent,
there is interference exists. Depth should be measured when the peak mode and the
valley mode are Consistent
.
Place the receiver just above the pipeline and make the receiver
body at the right angle with the pipeline and perpendicular to the
ground. At this time it is better not to select the vertical antenna
mode. Press the
key and the receiver will automatically adjust the gain. After the gain
adjustment is completed, the display shows: Testing. After 5 seconds, the depth of the target line
and the current in the tube will be displayed and then press the
key to automatically
restore the previous working status.
In depth measurement, a good quality signal is needed to be applied to the target line, when the
key
is pressed, the receiver will automatically adjust the sensitivity to the best. If the
receiver receives the too weak signals, the display shows the signal is too weak. Press the button
