Open the dust cap and
insert the tested fiber into the
laser connector.
Long press " " to turn on the device, the
red indicator light will light up, and the laser will
output continuous wave at the same time;
（If the optical fiber is connected, red light can
be seen at the end of the fiber under normal
circumstances; If the fiber is disconnected, there
is no red light output at the end of the fiber)
Short press the power button, the indicator
light flashes, and the laser pulse wave is output at
the same time; short press again to turn off the
red light.
Under normal circumstances, it will auto-
matically shut down if there is no operation for
15 minutes to extend the battery life.
Flashlight switch: long press
the " " button to turn on the
flashlight, which is convenient to
use in a dark environment and
realize the lighting function; short
press the " " button to turn off
the flashlight.

Please read all instructions and warnings before
using this product. Irregular use will cause
damage to the product or personal safety.
Using environment
1）Please read carefully and correctly understand the warning and
operating instructions in the user manual before using the
visual fault locator.
2）Please use the visual fault locator in strict accordance with the
user manual.
3）Lasers are harmful, so you need to pay special attention to
protecting your eyes. When working with laser, it is strictly
forbidden to look directly at the red light;
4）The laser is a heating device. Generally, the higher the
temperature, the shorter the life of the laser. When using it,
try to avoid high temperature environments. It is not recom-
mended to use it for a long time.
6）When it is not used for a long time, the lithium battery may self
-discharge, and it cannot be turned on when the voltage is too
low. Please charge it before using it.
5）After use, please cover the dust cap to prevent dust from
falling into it.
7）After using for a period of time, please clean the interface with
a special optical fiber cleaning cotton swab.

Standard configuration
This product uses a 650nm semiconductor laser as a
light-emitting device and is driven by a constant current
source to emit stable red light; it enters a single-mode or
multi-mode fiber after being connected to an optical fiber
interface to realize the function of fiber fault detection. It is
a fiber optic engineering construction and a fiber optic
network. An indispensable tool for maintenance, optical
device production and research.
