Description: Capacitor Analyzer
                                    During the past few years the performance requirements of
radio receivers have been reaching high levels which can
only be maintained by the use of high quality component
parts. These parts, especially condensers and resistors,
must have satisfactory electrical characteristics to perform
their designated functions properly, if satisfactory results
are to be obtained from receivers.
Condensers have a detrimental effect on reception, long
before they become permanently defective. The problem of
determining the quality or operating efficiency of a
condenser requires a complete measurement of its capacity,
leakage-resistance and power factor. Motor starting A.C.
electrolytic condensers used in connection with fractional
horse power motors present a somewhat similar service problem.
The Solar Capacitor Analyzers meet the requirements of radio
service men and engineers for inexpensive instruments which
will accurately determine the important electrical
characteristics of all types of electrolytic, paper, mica,
trimmer and air condensers.
Condensers may be tested for capacity, leakage, opens,
shorts, intermittent operation and power factor.
Accurately calibrated markings on several color-coded scales
are provided for convenient measurement of capacity and
resistance. These tests are made on a Wien Bridge with five
direct reading ranges on the Model CB and six ranges on the
CC. The power factor of electrolytic condensers can be read
directly from a scale which is calibrated zero to 50% power
factor. The capacity range of the Model CB is from .00001
mfd. to 70 mfd., and the resistance
range is from 50 ohms to 2,000,000 ohms. On the Model CC an
extra capacity scale up to 800 mfd. is included which
permits testing of motor starting condensers for capacity
and power factor.
The advantages of a bridge for capacity and resistance
measurements are well known. Some of these advantages
include independence of reading from line voltage
variations, and high degree of accuracy.
The use of a bridge circuit in an inexpensive instrument of
this type has been made possible by the unusual detector
arrangement employed. This detector arrangement consists of
a highly sensitive 6E5 cathode ray tube connected across the
output of the bridge.
The leakage test part of the equipment consists of a D.C.
power supply and a Neon lamp. A switch is provided with
voltage settings covering practically all electrolytic and
paper condensers which may be encountered in the field.
For leakage test of paper condensers, this device is
particularly useful because of its high sensitivity. In many
places in the radio receiver, such as for the gridplate
coupling condenser, the insulation resistance is of
considerable importance, and the sensitivity of this device
is entirely adequate for that purpose. The instrument will
be found useful as well for tests of insulating material.
Certain electrolytic condensers end their useful life by
losing capacity or by developing a high resistance contact
at the anode tab, due to corrosion. These defects will not
show up on a direct leakage test, but may be unerringly
detected by capacity and power factor tests as provided for
in this test instrument.
The instruction card furnished with this instrument and the
instructions to follow, specify certain limits which have
been set in connection with the leakage and capacity
measurements to be used as a guide in judging satisfactory
condensers. These limits have been chosen arbitrarily on the
basis of our experience with condensers made for use in
radio receivers, and, in general, condensers which meet
these requirements will be found satisfactory in operation,
while those rejected will interfere with satisfactory operation.
