press ON/OFF to turn it on.    And press it 

for 3 seconds to turn it off. Under power-on mode, 
press this key shortly to activate or deactivate the 
10-minute auto off function. The default setting is 
auto-off function ON when start the meter. 
Operators can press ON/OFF shortly to close the 
auto-off function. 

2) dBm/W

press dBm/W to enter absolute 

measurement mode. Press it repeatly to switch the 
display power unit between W and dBm 

3)

wavelengths, the current choice of wavelength will 
appears on the LCD 

4)  

REF

press REF key to enter relative 

measurement mode and it has 3 working modes: 

A) Directly enter the relative measurement: in 
absolute measurement mode, press REF to enter 
the relative measurement. Now the Ref value shows 
the previous saved power values. 
B) Save the reference value 

when enter the 

relative measurement mode, press REF for 2 
seconds to save the current absolute power value as 
REF value and show the relative power value in dB 
unit 
C) Enter the relative measurement mode and save 
current reference value: in the absolute 
measurement mode, press REF for 2 seconds to 
enter the REF measurement mode and save the 
current value as REF value which will appears in Ref 
position. Now the value in dB unit on the LCD and 
the vale means the difference value between the 
measurement value and REF value, meanwhile, the 
REF value will displays in the REF position. 

5)  Backlit is on when turning on the unit. It will turn off 

one minute later. Operators can press any key to 
make backlit for another one minute.

6. Operation 

6.1 Turn on/off 

—

  Press ON/OFF shortly to turn on the unit. Press 

ON/OFF for a few seconds to turn it off and press 

this key slightly to activate or deactivate the auto-off 
function. 

6.2 Absolute power measurement 

—

  Insert optical signal (Insert the pigtail properly), turn 

on the meter 

—

  Choose the wavelength via 

λ

 key. If the tested 

wavelength is not exactly same to the one in the 
power meter, then choose a close one from the 
power meter. For example, 1300nm wavelength is 
near to 1310nm, we can choose 1310nm to 
substitue 1300nm. 

—

  Press dBm/W to choose the display unit. The 

default wavelength is 1310nm and working mode is 
dBm. 

—

  After the above steps, the LCD will show the test 

power value. 

6.3 Relative power measurement

 

—

  Set the wavelength 

—

  Press REF for 2 seconds to enter the relative 

measurement mode. now LCD screen display 
00.00dB 

—

 Measurement: 

Insert 

the pigtail need to be tested

and introduce another measurement light, now the 
current value shown in the LCD is the difference 
value between the tested signal and reference 
value. 

—

  The reference value shown in the Ref position 

—

  Press dBm/W to review the current absolute power 

value. Press REF to review the current reference 
value. 

6.4 User self-calibration function 

   
 
 
 
 
 
 
 
During the operation, when operators need to calibrate 
the meter to be accordance with other meters. So our 
product offers operators self-calibration function, the 
following steps will tell you how to do:   

—

  Take out the batteries and pull up the switch 1 to 

“ON” position. 

—

  Put the battery back to the battery compartment and 

turn on the unit to choose the wavelength for 
calibration.

—

  Now connect it with a pigtail which we already know 

its power and press REF or dBm/W to increase or 
decrease the power value by 0.05d every time. Until 
the LCD display the pigtail’s power (Or the 
difference gap less than 0.3db), press ON/OFF to 
save the   

—

  Repeat above operation for other wavelength 

—

  After recalibrate each wavelength, please pull down 

the switch 1 (come back to the position, the 
opposition of the “ON” )and turn off the meter 

—

  End the user self calibration operation 

6.5 Auto off function 

The auto off is on when turning on the meter. Press 

ON/OFF to activate or deactivate this function. 

6.6 Replace battery 

—

  If the battery level is very low, please turn off the unit 

immediately and replace the batteries 

—

  Take out the batteries if not in use for a long period 

of time (like one month) 

—

 

NOTE: 

do not charge the non-rechargeable battery, 

dangerous! 

7. Maintenance 

1)  Keep all optical connectors and surfaces free 

from oil, dirt or other contamination to ensure 
proper operation.
