Avo ct-160 with problems

Geschreven door silvino op 11. Jun 2005 12:51:12:

Hello
I have seen that you have a tube tester AVO CT-160. I bought one recently
but I don't have a lot of experience in their handling and desire to make
you unite questions.
are you able to your to help me?

I verify flights and short circuits and everything seems to work perfectly.
But when I try to measure MA/v, I have this problem:

I put the disk of MA/V in the position SEP ZERO and I adjust the controls to
position the meter to zero of the scale, but the meter is not still, he/she
moves slowly to a side or the other one and it is not still.

I move the disk MA/V until the position that the book indicates me, and the
meter ascends correctly, but past 1 second, the meter moves slowly to a side
or the other one again, and it is never still.

is it normal these oscillations of the meter?

I don't have experience with this tube tester, but I don't believe that this
is the correct thing

That problem can have? I have cleaned all the contacts and I have measured
tensions, and everything seems normal

I will be very grateful if you can answer me. GREETINGS FROM SPAIN
