Reading this email lead me to ask you if you know if any of the
Doumentation on Service/Repair was saved on the 3810A Total Station??? I
have one and would like to find info in case mine "goes west"!!? I read the
June, 1980 HP Journal on the unit and got a kick out how they tested it in the
Shop,? having you confirm it makes even sweeter!!!
?
I have re-built that battery pack and am looking for the Lens to reduce the
return level at short ranges, but no luck yet.? I did pick up the correct
Triple Prism set for it!!
?
Nice to hear from someone who has worked/designed the Eqipment we all Love
and Charish!!

[HP-Agilent-Keysight-equipment] HP34702A Ohms converter issues
Sorry,
I just assumed that since the 3468/78A/B's came out in the 80's,? I was a
young guy at that time and the design folk I encountered were older than I
was.? Hence the assumption was you were also retired? I had very
little contact with the HP Loveland folk, except for the DMI division - I
serviced the 3800, 3805, 3810, and 3820 for 2-3 yrs. before I shifted over to
the SA division products from Santa Rosa.? I really enjoyed hearing the
info discussed on the 34702A - I have 1 or 2 still.? I also serviced
3455's for about 9 yrs.? Don't have this one, but do have a 3456A, and
34401A's.? I will save up some cash and want to get a 3458A - the
ultimate DMM ever made.? The Datron's were good, but finicky and some
times tricky to use.? Their calibrators are pretty phenominal, but the
Flukes are easier to use and program.
I
think all of the HP, Agilent design engineers were truly at the top of their
game.? 98% of or products during the heydays were unique, durable, well
documented, and supportable.?
The
Yokohama products and German products often left you scratching your head,
until you got into the designer's head.? They also liked to create
unique, undocumented IC's and assemblies that are irreplaceable.- ie, 8112A's,
and 8116A,s each have 3? LSICs that can now only be gotten from
cannaballized units - they are prime failures in these units.?
My
best regards,
