Note:
1,Range of wavelength:  a standard working wavelength that we specified: min-max, the optical power meter within this range can work well with all indicators meeting requirements.
2,Power measurement range:the maximum power that the meter can measure as per required indicators.
3,Uncertainty: the error between the test results and standard test results over a standard optical power .

Button description
1,Turn on / off
Press the button to start within a second, then press the button to turn off the power.
2,AUTO/OFF
Press the key to turn off or turn on the automatic shutdown function, and the upper left corner of the LCD will display the prompt at the same time.
3,ZERO
Press the key to realize the automatic clearing of the optical power meter.
4,LIGHT
Press the key can close or open background light; LCD top left corner can show the hint at the same time.
5,dB
The relative measurement of optical power can be carried out at the corresponding wavelength.
6,
7 ,different wavelength optional (850nm,980nm,1300nm,1310nm,1490nm,1550nm,1625nm) LCD showing at the same time.

Screen display instructions
The tested power are shown with the forms of dB,dBm,mW,uW,nW; there are 7 types to show wavelength.

Calibration function description
At the same time press the "LIGHT" +  button, then enter the user mode, the lower right corner of the screen shows the letter "CAL", the following function is in the combination button pressed after effective.

Function	Push-button	Comments on a form
Increase 0.05dB	dB	*1.01158
Reduce 0.05dB	LIGHT	*0.99855
Preservation	ZERO	Press the boot button(Store to flash)
Switching wavelength
Restore factory settings	+ZERO	Display "FAC", The default value is also read into the array.

Measurement of relative power and absolute power
1,Absolute power
If the 1310nm wavelength is chosen, the screen will show the present value, including linear value of absolute light power and non-linear value when the tested light is connected.
2,Relative power
When the wavelength is set, in the mode of absolute light power, connects the tested light to test the present power value. dB is pressed at this moment and the present power value is reference (dBm is unit). Another tested light is connected and the absolute and relative power are shown.

Standard configuration
The host, light power meter product warranty card, certificate, instructions, Oxford roolls (apolegamy), three 5 dry cell batteries (apolegamy), lithium battery (apolegamy), charger, adapter (apolegamy) (SC and FC standard, ST apolegamy).

Charging function (apolegamy)
Battery indicator does not display the work, when the power is not enough to provide normal work, power index every second flash once, 10 seconds after the automatic shutdown, then do not start again, with the power adapter is equipped with charging after the boot.

Solutions to common faults

Malfunction Tips	Cause	Solution
LCD monitor weak	Insufficient power	Charge or change battery
Could not display when starting	Lack of power or other	Restart machine or charge, change battery
abnormal data display of LCD	Adapter fault, dirty or be locked	Reconnect adapter and clean sensor

Routine maintenance and maintenance
1,Please keep cleaning of the sensor frequent and there should be no fat, no pollution and not use dirty and not standard adapter. Do not insert the end face of bad polished surface, or it will damage the end face and there will be error in testing.
2,Stick to an adapter as much as possible.
3,Once the machine is unused, please cover the dust cap to keep the end face clean prevent from exposing in the air and prevent from attaching the dust which leads to the wrong measurement .
4,Carefully plug optical adapter connector to avoid port scratches.
5,Clean the sensor surface periodically. When cleaning the sensor surface, wipe it gently in the circumferential direction with a special cleaning swab.
