Arcograph ZEUS RF (IMAGO) problem
November 27, 2019 10:11
Problem: KV is out of tolerance, I choose 80KV, measured KV with KVmeter PMX-III is 67,8KV.
Can you help ? I need service manual or at least adjustment procedure for KV.

Hi, Maybe I have only on paper. sorry. anyway you should have a box beside the system. check connector (usually you find burnt contact) and in case make a straight wiring connection (without connectors).
check mA on tube, if are too high the result is KV too low. In the box you should find 2 variac; 1 big (KV adj) and 1 small (mA adj). both variac motors are connected to a board where you'll find 2 trimmers. adjust those trimmer and you'll see move motor Kv and mA ... check and check and check and check... until kv and mA are correct.
there's no way to have a standard procedure because there are 2 or 3 version of low voltage feedback board and ratio KV/V is not the same for all version. good luck
