Subject says all.
I have a very poor scan of the 7150 Service Manual. 7150+ is somewhat
different.
I have sent an email to Emerson (successors of Solartron Mobrey) in the hope
that they may still have this. Manuals Plus has a photocopy at USD30.
Hoping to find a complete original or a good
Mark,
Did you save the eprom segment after setting after changing the number of
survey points. Mine (rev 3.0) knows it was told 1 survey points.
PS Still waiting for your reply about the SG504 levelling head kits.
Cheers
Dave

If I use 10 mtrs (33 ft) of RG58 cable would I be right in thinking that I
should set the PPS offset to -2.2e-08 (assuming progation speed of 0.66)?
Thanks

Does anyone (preferably in the UK) have 1.0-14UNS-2A thread cutting die they
would be prepared to lend me (preferably a die nut type as I don't have a
die stock)?
