the “Auto-o” will display on the left bottom of the screen. On the

“Auto-o” status, the OPM will turn o 10 minutes automatically.

1. Take o the dust cap; connect with the patch (reference) cord.

Please conrm the connector and the ferrule of the patch cord is

clean.

2. Turn on the OPM.

3. Select the wavelength. Short press , select the calibrated

wavelength, notice that the selected wavelength must be the same

with the laser source wavelength.

4. To change measurement units, press to switch between the

absolute measurement (dBm) and relative measurement (dB) and

xW of the optical power.

Relative value measurement: Each wavelength can set a Ref value,

Press ,set the current value as the ref value, and automatically

calculate out the relative value.

Data processing: This OPM can store up to 1000 data les. When

saving, press button ,at the right top of the screen it will display the

data saving number (ex: 0001, 0002, etc). Then repress button again

to conrm save. The saving number will disappear at the top right of

the screen. For how to transfer the data to PC and view or delete the

data please refer to the software CD.

Wavelength Automatic Identication: Press the button of the

OPM till appear “---AU “ at the right top of the screen;Press the

button of the OLS (light source),so it can relieaze this function.

Frequency Detection: OPM can test the frequency of the OLS. If OLS

output frequencies of 270Hz, 1KHz, 2KHz accordingly, OPM will detect

the frequency and show it on the upper right of the LCD automatically.
