|The Capacitor Checker
on the market in 1961. In 1968 it was replaced by the IT-28
was produced until 1977. There is only minor
differences between the IT-11 and
mostly it is about
and color. It
is a utility capacitor checker
instrument to check whether a capacitor is "open", "shorted", "leaking"
or "OK". It can be used to
determine the actual capacitance of a capacitor but also the actual
resistance of a resistor. The IT-11
is also an excellent utility to reform electrolytic capacitors. In my IT-11
I have replaced the internal
reference capacitors since they were way out of tolerance. An electron
beam tube or "magic
eye" is used for
the read-out indicator.
This is a description how to reform
electrolytic capacitors with the IT-11 (and IT-28).
