should be appropriate.

Clamp connection
The biggest difference between the clamp connection and the inductiveconnection
is clamp connection uses an external clamp to apply the transmitter signal to the
target line without the need for an inductive coil inside the transmitter. The
methodof clamp connection is basically same as the direct connection method.
1. Receiving and Locating
The Underground Pipeline Detector is used to position the target pipeline,
measure the depth and the current in the target pipeline.
The position, direction, and depth of the target pipeline can be detected by the
receiver when the signal of the transmitter is successfully applied to the target
pipeline. Location and depth of the underground pipeline is the most important
information and also the most important job.

Location
When detecting the position of the target pipeline with the receiver, it is
necessary to pay attention to the factors that may interfere with the positioning
accuracy at any time, to prevent the transmitter signal from being overlapped with
the adjacent pipeline, so that the detection result is deviated.
(1)Preparation
1) Check battery voltage
: Turn on the receiver and check power. Fully
recharge the receiver before use.
2)Frequency selection
: Press Frequency key and set the required frequency.
Set the same frequency with the transmitter if the active mode is being used.
3)Sensitivity setting:
Adjust the up or down key to increase or decrease the
receiver gain so that the bar reading is at 60-80% of the full scale.
4)Mode setting:
Press the mode key to select the appropriate operating mode as needed. The
receiver provides peak mode, wide-peak mode, broad-arrow modeandvalley
mode.
(1) Peak(Maximum) Method
The peak method uses a single horizontal antenna (broad) or double
horizontal antennas to receive the horizontal component of the target pipeline
signal and the receiver gets the maximum responsewhen the receiver is on the
target pipeline. The single horizontal antenna wide-band mode is used to locate
deeper pipelines with the highest signal sensitivity. When the receiver is directly
above the detected pipeline, the signal strength is the largest, the response range
