Measurement Loss 

 

1.

 

Do not disconnect the master cord from the light source. 

2.

 

Disconnect the master cord from the power meter port. 

3.

 

Connect the trace to be measured between the power meter port and the master 
cord that is attached to the light source. An extra master adaptor is required 

(pic.4) 

4.

 

The power meter display will report the value simultaneously with the message 

“LOSS” or ”GAIN” in dB. 

5.

 

This value represents the difference between the reference and the performed 
measurement. 

6.

 

If the value will be displayed with the message “LOSS”, the trace to be measured 
has just this loss. 

7.

 

If the value will be displayed with the message ”GAIN“, this means that the trace 

to be measured has been compared with the reference for this gain. 

8.

 

The value of the loss can be stored in the internal memory 

 

(see “SAVE RESULT

” chapter

).
