The measurement value will appear when there is light passing through the optical channel, otherwise “LOW” will appear. 5.2 Power Off While the power meter is on, off the device. press and hold it for about 2 seconds to power 5.3 Set threshold value The setting of threshold value will influence the status of the three indicators and the status of measurement results. For example, if the option “1310nm” is set as: -15, -30, -40, it means that: when the optical power measurement value of 1310nm is greater than -15dbm, the optical circuit will be normal, the moment the 1310nm indicator turns in green; when the optical power measurement value of 1310nm is within -15dBm～-30dBm, it means that problems may exist in optical channel but it is still usable, the moment the 1310nm indicator turns in yellow; when the optical power measurement value of 1310nm is within -30dBm~-40dBm, it means that there exists abnormal in optical channel, the moment the 1310nm indicator turns in red; if the optical power measurement value s less than -40dBm, the moment the 1310nm indicator turns in dark, “LOW” appears in the LCD area where the results are displayed. To conclude, “green” represents “Pass”, “yellow” represents “warning”, “red” and “dark” represent "Error". So does 1490nm or 1550nm test. While in main interface, press , a menu as below will pop up: Select the setting you desire by pressing and , press , to enter the setting interface as shown below: Here user can set language, time, auto power off, incidental mode, threshold value, calibration. For example, if you select “threshold value”, the setting interface will appear as below. to select option. Press or to increase Press or decrease the threshold by 1 respectively. If the option is Save, press , the change will take effect. If the operation is Default, press , the threshold value will be rest to be default value. 5.4 Calibration This ability is designed to set tolerance, it will increase the power reading by 1. Enter setting interface, select Calibration, press , the calibration screen will appear as below: Press to select the option you desire. Press or to increase or decrease the calibration value by 0.01 respectively. If the option is Save, press , the change will take effect. If the operation is Default, press , the threshold value will be rest to be default value. 5.5 Data upload The measurement results can be saved in the device, or be uploaded to PC using upper computer software. Connect one end of data cable to the port of PC Link in the device, the other end USB port of PC, run the upper computer software, and set the software as per default configuration, then you can directly click “Upload” on upper computer to transfer the data to PC. 5.6 Measurement procedures (1) Press to power on the meter, enter threshold value setting interface to set threshold value. (2) Connect in the optical fibre to be tested. It supports measurement of three wavelength i.e.: 1310nm upstream, 1490nm and 1550nm downstream at the same time. For example: threshold value is (+3dBm, -10dBm, -30dBm), the measurement readings of the meter are: the value for 1310nm upstream test is +1dBm, which is within +3～-10dBm, it means that the optical circuit is normal, so in the testing screen, the power value for 1310nm is displayed in green; if the power value falls within -10dBm～-30dBm, it means that the optical circuit may be wrong but is still usable, so in the testing screen, the power value for 1310nm is displayed in yellow; if the power value falls outside of threshold value, it means that there exists abnormal in optical circuit, the power value of the optical circuit is too strong or too weak, so in the testing screen, the power value for 1310nm is displayed in red. So does 1490nm and 1550nm test. 6．Applications FTTx/PON opening: it is used to measure all PON signals during opening stage, in order to verify and ensure network standards are satisfied; FTTx/PON maintenance: it is used to solve various transfer problems, e.g.: dirty connector ends, bending, broken optical fibre, any of such problems may produce signal loss or decrease transfer performance. 7．Maintenance 1. Regularly clean the end of sensor, keep it free of grease, dirt. Don’t use dirty, non-standard connector, don’t insert in the end in poor polishing conditions, otherwise the sensor's end may be damaged, otherwise the performance of entire system may degrade. 2. Use only one adapter if possible. 3. If you are not going to use the tester for the time, cover the dust-proof cap immediately to keep the end clean. Long-time exposure in air may gather dust therefore influencing measurement accuracy. 4. Plug and unplug the adapter with care, don’t leave any scratches on the ports. 5. Regularly clean the surface of sensor, when cleaning the sensor, please gently wipe the surface using cotton swab by circling the perimeter. 6. Handle the tester with care, protect it against fall or collision. 8. Warranty No parts of the product can be repaired by user himself. Warranty period: 18 months since the date of shipment.
