Input/Direct/Reflected power levels readings adjustment circuit 

This circuit (

 Par. 5.4 - part # [38]) mounts trimmers used to adjust the input, direct and reflected power readings shown  on the 

LCD display: 

 

 

[69] 

Reflected Power reading adjustment 

– use this trimmer to adjust the reflected power level reading.

 

[70] 

Input Power reading adjustment 

– use this trimmer to adjust the input power level reading. 

[71] 

Direct Power reading adjustment 

– use this trimmer to adjust the direct power level reading. 

 

INPUT POWER READING ADJUSTMENT:  

check with an hi-precision R.F. power-meter the level of the driving signal coming from 

the Exciter, then adjust the trimmer [70] until the display shows the same power reading.

 

DIRECT  POWER  READING  ADJUSTMENT

:  with  the  equipment  in  normal  operation  (ON  mode),  and  the  display  showing  the 

working page (e.g.

10.2), check with an hi-precision R.F. power-meter the rated output power, then adjust the trimmer [71] until the 

display shows the same direct power reading. 

REFLECTED POWER READING ADJUSTMENT

: check the reflected power level with an hi-precision directional power meter, then 

adjust the reflected power level reading accordingly, using the trimmer [69].
