Hi all,
Does anyone have a manual or schematic available for test set I-135
for the BC-611?
My test set had an open circuit meter moving coil. I replaced it with
a Japanese 1mA movement.
Now it reads about 1/3 of what it should. So I need to massage the
meter resistors.
Oh, I put the movement inside the original meter case so it looks
original, no mutilation here.
Anyone want to tackle rewinding the movement coil :-)
An interesting observation was that there were two steel screws on
the meter case near the magnet poles.
I assume these were to adjust linearity over the range, as the screws
were screwed in at different lengths.
I have not seen this before.
Cheers,
John Kidd. VK3FPRC
