Please check all the parts before using the locator and transmitter to ensure that the
battery is sufficient and instruments are working well. In case there are any following
conditions, please solve them before use.
1 Locator check
1) Battery power check: press the power button to check the battery power. If the
battery is fully charged, the battery symbol in the display will show all the five
lines; when the battery symbol has only one line, the battery symbol will flash
indicating that the battery is low and it needs to be fully charged.
Full battery
Almost run out and please recharge
2) Operating frequency check: press the frequency key to select50Hz and adjust the sensitivity.
Point the locator to the fluorescent lamp 1 meter away and turn on the fluorescent lamp. A signal
soundwill be heard, and the monitor will display strong signal too.
3)Inductive method check: find a place without any interference and put the transmitter on the
ground. Turn on the transmitter and select the output power percentage and frequency. Then
point the receiver (about 5 meters away from the transmitter) to the transmitter and keep the
same frequency as the transmitter. When the sensitivity is adjusted to be large enough, the
receiver should have a signal response.
4) Clamp method: When the external clamp is inserted into the transmitter output interface, press
the button ON, the transmitter will select the frequency as33KHzautomatically. Put the clamp on
the target pipeline and adjust the transmitter power. Turn on the receiver and select the frequency
as 33KHz. The receiver should have a signal response along the pipeline.
Note: For the Inductive method, you can only choose 65KHz and 83KHz frequency. Without the
direct signal output or clamp inserted, the instrument will select the inductive
modeautomatically. In the inductive mode, only 65KHz and 83KHz are available; In the clamp
method, you can only choose 33KHz. When the clamp accesses the transmitter, the instrument
will selectthe frequency as33KHz automatically.
When using the inductive method or clamp method, the instrument display shows the
percentage of output power, and the trianglefor percentage on the top line is lighted.
