1. Summary
With better performance and special fast field testing
function, ST815 adopts advanced technology of exact light
and dealing with technology and to support high
performance light for the field test and the lab development.
It has been an ideal instrument for maintenance and
development of optical network equipments.
ST815 can be widely used in various kinds of optical cable
testing fields, such as LAN, WAN, CAN, CATV and
long-distance Fiber Network.
Together with ST800 series optical power meter, ST815
Laser Source can support stable light signal on many kinds
of wavelength, it can recognize the fiber, test the fiber loss
and continuity accurately, help to evaluate the transmission
quality of fiber chain as well.

Attention: The light source maybe hurt to eyes, so it is
forbidden that the user looks at the light output end
directly when you operate the instrument in order to avoid
the light burn the eyes!
Note: If you use dry battery, do not recharge the
battery. That is dangerous!
Please pay attention to the followings in order to keep the
performance of the instrument and prolong its service time.

Press " " button to turn the backlight on or off. When
the backlight is on, the sign will display on the
screen, otherwise this sign disappear. If the backlight is
in a closed state, the operation of any function key will
open the 8 seconds’ backlight besides pressing "start"
button.
5, Under-voltage
When the battery voltage is low, the power indicator
become , when the battery voltage is lower than
warning voltage, the equipment will alarm "Low voltage"
every 20 seconds. When the battery voltage is lower
than protection voltage, it will be in auto turn-off state.
The equipment should be charged in time, charging time
is about 4 to 6 hours, please observe the charger, if the
charging indicator light becomes from red to green,
which means the battery is full.
6. When the equipment is not in use, the user should
immediately cover the dust cap to keep the adapter
clean.

5. Operation
1. Power On/Off
Press "On" key 2 seconds to start the equipment, LCD
displays operating wavelength, battery voltage and
modulation state. When you open the ST815, it works on
1310 nm wavelength and continuous light output state;
press "off" key 2 seconds to close the equipment. The
system defaults auto-shutdown, auto shutdown logo
is displayed on the screen. Open and turn off the
automatic shutdown function: Press "off" button on the
screen, auto-off mark disappear, which shows the
automatic shutdown function is closed; and then press
"off" button, automatic shutdown logo is displayed on
the screen at this time has indicated that the automatic
shutdown feature open. If there is no operation for 10
minutes, the equipment will automatically shutdown.
2. Wavelength switch function
Press "wavelength" button when power on, you can
switch different wavelengths, and LCD screen display the
different output wavelength.
Note: If you want to switch the 1310nm, 1550nm
wavelength to 850nm, 1300nm (ST815C) or 1625nm
(ST815D) or 650nm (ST815E), do not forget to change
the output adapter.
3. Modulation output
Press the "Mode" button, you can achieve the modulated
light 270Hz, 1 kHz, 2 kHz, 330Hz, 650nm red light 2Hz,
continuous light output, at the same time, on the LCD
screen the equipment will show the corresponding
modulation frequency of the state.
