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.
Thanks

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
Hello Good Morning
My control board has four potmeters. On the board is written P1- corrente motore mA, P2 offst motore KV, P3 offset motore mA, P4 corrente motore but I can not identify them on the board; I send a foto by separate mail to see if you can help.
The problem is Kerma- area is higher than it should be: it is 120mGy.cm2 and should be less than 100mGy.cm2.
Measured 78KV when I choose 70 KV

Thank you Manlio
Motor of KV moves but Variac was not moving.
Pin on the shaft was out, mechanical problem
