The 490B have been intended for the checking and rejuvenating
of the cathode ray tubes (CRT) for both color and black-and-white television
sets and monitors.
With this instrument you will be able to find and to
repair leakage or shorts by measuring the RGB current of cathodes.
You will also be able to plot voltage/current features and to rejuvenate
each cathode separately.
