1.4 Applications ◆Measuring power output. ◆Measuring loss in fiber cable or device. ◆Measuring loss in a fiber device. ◆Identifying system problems. 2. Functional description 2.1 Startup and shutdown Press button to turn the tester on. Press for approximately 2 seconds to turn it off. 2s continuously, the meter will be closed. 2.2 Auto-off function The Auto-off function is auto-matically enabled when NF-906 is turned on. the unit will turn off after 15mins.Auto-off is displayed when the feature is on.
2.4 Description for control panel λ dBm W REF Optical power meter (1)Power Key Used to turn on the power meter, if press it by 2s continuously, the meter will be turned off. Auto-off function selection: this key can be used to activate or shut down the Auto-off function, in addition, if there is no operation over 15min, the power meter will be off automatically.
(4) Calibration Key REF Press this key continuously to save the current power value as reference value, which will be on the right upper corner of screen; if just press this key shortly, it will be switched to relative power measurement, while the reference power value will be shown on the right upper corner of screen, and show the relative power value between the current measurement and reference power, the unit is dB. 3. Handling instruction 3.
(4)At the middle display-area of screen, the value of power will be displayed, the unit is dBm,W,dB. (5)At right upper display-area of screen, show reference power value, and the wavelength value at the left. (6)The user self-calibration function is just the course of power conversion and calibration.( calibration of each wavelength) A. After open the battery cover. Turn the toggle switch to “ON” position, then it is available to carry out power calibration after startup. B.
3.3 Absolute power measurement (1). Use one major bridle wire to connect the output port of light source and the detecting port of fiber power meter as shown in the following fig: NF-906 Fiber Power Meter Light Source (2).Turn on the light source to enter working mode and select wavelength to be tested. (3).Turn on the fiber power meter and select specified wavelength. (Selection method: press the λ key to select the desire wavelength value) (4).
(1). Connect the desired connector to the meter, connect the two ends of optical fiber jumper with light source and power meter. NF-906 Fiber Power Meter Light Source (2). Turn on the light source and power meter to enter working mode and select wavelength to be tested. (3).
(5). Shortly press REF key, the value on screen is the loss value of the bridle wire being inserted. (6). If to measure the loss of optical fiber link, it is necessary to carry out local initialization reference for light source and optical power meter, as shown in the following Fig, read the initial reference value on optical fiber meter, and it is available to press the REF key continuously to save this reference value. NF-906 Fiber Power Meter Light Source (7).
4.Maintenance ◆Always clean the optical connector each time a connector is attached. ◆Avoid exposing the unit to temperature extrames. Condensation can form inside the unit and affect proper operation. ◆Ensure the dust cap is in place any time a connector is not attached. ◆Store the unit in clean and dry place. 4.1 Probe cleanness Clean the probe of optical power meter regularly. 1.Open the dustproof cap 2.Screw off the adapter of power meter 3.Use 2.
4.2 9V battery replacement When install or take out the battery, the following information may be helpful for your operation: ◆When the battery energy is lower or no 9V battery installed, a icon will be on screen. ◆Only an eligible 9V battery can be engaged ◆If no use for a long time, take out the 9V battery in case of corrosion and damage to internal components. 4.3 Calibration and measurement Under proper conditions, if this meter can be used in a right way, a better performance can be guaranteed.
