Информация:
                                    The Supreme Model 504-A is a complete tube, battery
and set tester for checking the static condition of
radio receivers and parts as well as many other types
of electronic apparatus.

The tube testing circuit of the Model 504A is designed
to classify receiving type tubes by the emission
principle. This type of tester has long been recognized
to be the most accurate of any simple test on vacuum
tubes. By checking the cathode or filament, as the
case may be, for its ability to emit electrons or
current to the other elements of the tube, the quality
of the tube may be accurately classified. In setting
the limits on the tubes as shown on the roll chart,
Supreme engineers worked closely with tube manufacturers.
Recommended loads and voltages are used throughout the
tester.

The battery testing function provides a load upon the
battery or cell under test which represents the average
current drain on that particular type of battery.
The discard points used in this section of the Model
504-A are those recommended by the manufacturers of
portable radio batteries.

The multimeter section of the Model 504-A incorporates
seven choice functions built around a meter with a
sensitivity of 500 microamperes. This section includes
a total of twenty-nine Carefully selected ranges and
also provisions for electrolytic and electrostatic
capacitor checks. Twenty-seven multimeter functions
are operated from only one pair of pin jacks by means
of two sets of push button switches which make it a
completely automatic unit.
