Description: Quick Check Capacitor Analyzer
Information:
                                    The Solar QCA Capacitor Analyzer provides radio service
engineers and laboratories with a capacitor analyzer that
combines in one instrument a convenient and simple method of
making a complete analysis of condensers under conditions of
operation, static or dynamic.
The performance characteristics of radio and video receivers
have imposed requirements which can be maintained only by
the use of high quality component parts. These parts,
especially condensers, must have the proper 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 entirely defective. The problem of
determining the quality or operating efficiency of a
condenser requires a complete analysis of its constants.
In this instrument condensers may be tested for capacity,
leakage, insulation resistance, power factor, opens, shorts,
intermittents, and r.f. impedance. Also with the full
development of the Quick-Check features plus the Wien
Bridge, we find it possible to present an instrument which
will give every qualitative and quantitative measurement of
capacitors necessary in modern servicing of a simple indication.
Model QCA tells the performance story of all types of paper,
mica, electrolytic, trimmer and air condensers. Checking for
quality is done under conditions of either static or dynamic
performance; the condenser under test may be operating in a
circuit, or it may be disconnected.
Accurately calibrated markings on the panel are provided for
convenient measurements of capacity. These tests are made on
a Wien Bridge with three ranges by multiplying the direct
scale reading by the bridge constant.
The power factor of all types of electrolytic capacitors is
indicated by the degree of opening of the electron-eye.
The capacity range of the instrument is from .00002 mfd. to
70 mfd.
Only two terminals are used for all tests. The switch in the
QCA Analyzer automatically connects the unit under test into
the proper circuit.
The leakage test part of the instrument consists of a D.C.
power supply and electron-ray tube. A selector switch is
provided with voltage settings covering practically all
electrolytic condensers which may be encountered in the field.
The insulation resistance range of the instrument provides
quick and positive means of determining faulty condensers.
The quick-check feature of the QCA consists essentially of a
complex balanced radio frequency oscillator, an electron-ray
tube indicator and a source of power.
