Dear Bruker Users,
The He level meter on our AC200 (vintage 1996) has a fault and we are
trying to repair it. Unfortunately the circuit diagram supplied with the
instrument does not match the circuit board in the BSN18 rack.
Can anyone help out with a copy of the correct circuit diagram? The
identifying marks on the board are as follows:
Interface + He Level <-- these lines are on the component side
Z1P2420b
Ser No Z808/2072 F20 <-- these lines are on the sticky label on the back
BSN18 EC00
The identification of the drawing we have is as follows:
Print H3P0053D
Dwg H3S0203D/Z4-3S 3805C
Date 5-4-82
There are significant discrepancies between the two (e.g. a relay on the
board is an i.c. on the diagram) which are hampering our repair. We'd
rather not have to pick our way around the board drawing our own diagram!
Thanks for your help,
Alan
