Not yet but dont worry too much at the mo - if your motor and dish are nicely in line with each other and the 2 appropriate u bolts nicely tightened and the rim of the dish is more or less upright (or top rim leaning back slightly compared to bottom rim) then I suspect a careful exploratory East/West sweep either side of due South (with dish and motor locked in line so that you are using the pole as an axle)through about 20 degrees might not do any harm. For now only tighten motor to pole and and dish elevation bolts sufficient to stop the dish sliding about on its own so that you can adjust these 2 settings (up/down left/right) fairly easily if you lean a bit on the dish - there is a fine balance to finding this tightness - especially as you dont want to fall off the ladder.
When you peak on the meter, switch receiver to standby, take out meter and connect lnb to receiver coax. Switch on again and check your receiver meters per my previous post- if you have found a sat you will get signal strength of about 97% and a quality of over 65% - this will allow you to positively identify the sat and find a few channels.
If your motor has usals as well as diseqc this can help us - does it have usals?
If it does and you enter your lat/long properly you can tell motor to go to a convenient sat near due south and without worrying what your receiver displays at that moment, nip up the ladder and try and then align dish and motor for best strength/quality on the selected sat -once you have got it , tighten up bolts and in theory that should be job done.
With or without usals the inline meter is a useful device to do a preliminary initial setup but it must be taken out when you are checking with receiver because it seriously attenuates signals.
Happy hunting!
