4. Operation
4.1 ON/OFF & Charge
Turn on: Press on the front panel for 2 seconds. If the instrument starts normally, the PWR indicator
will light and the LCD will display the main interface.
Turn Off: Press the OFF button, the display shows: Confirm to turn it off? Yes: OK; NO: ESC
Turn off by force：when the tester works abnormally, press for 6 seconds to turn off the tester by
force.
During normal use, the battery level will be displayed at the upper right corner of the OTDR. When the
battery level is too low, the battery level symbol will turn red as warning. Please charge it with the charger
provided by factory. The remaining charge will be displayed at the top of the screen. The red color of LED
on the charger indicates that charging is in progress, and the green color means it is already fully
charged.
After turning on the OTDR, please enter into the system settings from the main menu, set the parameters
like date, time, backlight, brightness, auto power off time, button tone and other information.
4.2 Connect the fiber
Note:Light is emitted from the light source port of the instrument. In any case, the optical interface of the
OTDR and the end of the pigtail connected to the optical interface are not facing the eyes of the operator
or other personnel, otherwise the eyes may be injured. Even blind!
Before connecting the fiber, please check whether the connector type matches or not, and also check
whether the connector is clean or not; both the unmatched connectors and the contaminated connectors
can cause inaccurate measurements and can even damage the the instrument. The correct way is to
clean the jumper, especially the surface with absolute alcohol before inserting the fiber optic connector
(jumper). After the alcohol has evaporated, connect it to the instrument.
If the light source port is not connected to the fiber optic cable, immediately cover the dust cover to
prevent dust from adhering to the light output port of the instrument.
4.3 Setting measurement conditions
4.3.1 Auto Test / Manual Test
Auto Test: Click[OTDR]->[Setting]->[Test]->[Test Mode]->[Auto]->[OK/Save] / [Start Testing].
Manual Test: Click[OTDR]->[Setting]->[Test]->[Test Mode]->[Manual]->[OK/Save] / [Start Testing].
