MT-7612F Multi Function Optical Time Domain Reflectometer

WARNING
Any undefined change or modification of this manual will deprive you of the right to operate the equipment. To reduce the risk of fire or electric shock, do not expose the equipment to rain or humidity. To prevent electric shock, please do not open the shell, and it must be repaired by qualified personnel.
This device supports on-line test with signal, should satisfy following norms:
1270nm / 1310nm / 1490nm Power <+10dBm
1577nm Power <0dBm : 1550nm Power < -20dBm
If out of range, it may lead to device broken, which is out of warranty range

NOTE
As the laser is harmful to the eyes, don’t look directly at the laser outlet and don’t attempt to disassemble the cabinet.

PRECAUTIONS FOR USE

Using the battery
The device can be recharged with a special battery, and can not be mixed with different types or capacity batteries.
Avoiding condensation:
Sudden changes in temperature should be avoided. Do not use the device immediately after moving the device from the cold area to the hot area, or when the room suddenly heats up, because the device may have condensation phenomenon.
If the temperature changes abruptly , stop using it and take out the battery, and the power can be switched on after atleast an hour.

Storage:
When the device is not used for a long time, please take out the battery to avoid the damage caused by battery leakage.
The content of this manual is for reference only, and everything is based on the actual product.

OTDR-Measure settings

The judgement of events list is based on measure setting. Wrong setting might leads to wrong or missing events In OTDR interface, press “ ” button to enter measure setting Wavelength-—-Wavelength of laser.
Scan mode—Manual and auto mode. Under auto mode, device will match the distance range and pulse width.
Scan type- Real time: Real-time measurement can quickly judge basic faults of optical fiber; Average: judge the line condition more accurate, get a better SNR measure curve.
Range—Match with the length of measured optical fiber, usually over one level.
Pulse width—Set the pulse width of output laser.

Average time—Set average time: The longer average time, the better measure curve.
Splice loss-—-Treatas an event when the loss is higher than setting value.
Reflection threshold-—-Treat as an event when reflection is higher than setting value.
End threshold—Treat as the end of optic fiber when loss is higher than setting value
Optical detector—
Before measurement, set to check whether light input s in the fiber or not.
Real time analyse—
Set to turn on or turn off the event analysis after real-time measurement.

OTDR-Measure

Press the” ” button in OTDR interface to run measurement Real-time:
During measuring, you can change range, zoom in or zoom out with direction buttons and zoom control button. Press” ” again to stop.
If real-time analyse function is on, the device will analyse events after measurement Average:
Average measurement can judge the line condition more accurate. It can get a better SNR and fits high requirement circuit. User can set measurement time from 5 to 180 seconds. The device analyses events and generates event list automaticity.
