problems caused by electrolytics has never been easier,
now that you can locate these bad capacitors easily
without having to unsolder them, and without spending
time troubleshooting, by using the
88A Series II.
As a cap
ages, it can cause problems in the particular circuit it
is in. In a CRT vertical section, it can cause underscan or
overscan problems. In audio or mpx circuits it can cause
distortion or low audio. In the syscon supply it can
cause intermittent functions and mpu confusion. In the
video circuits it can cause a fully scrambled picture. In
VCR or camcorder servo circuits, it can cause unstable speeds. Most VCRs
and big screens also use surface mounted electrolytics in
the sound MPX decoder module and video PIP and
convergence circuits. High-end audio, video and computer products use tantalum capacitors
that can become leaky by as much as 500 ohms. Computer motherboards are another
user of electrolytics that must have super-low ESR, or else strange problems and
freezing can occur.
a cap in circuit is more difficult than measuring a
resistor, because circuit resistance and
capacitance can affect readings. Some "capacitor
checkers" claim to work in circuit, but they give such
erroneous readings you have to unsolder and re-measure
each cap out of circuit anyway. Some of the most
expensive LCR meters will not measure
capacitors accurately in circuit. Some meters measure the
capacitance at two different frequencies, and show it as
two different readings!
The trick to locating bad
capacitors in circuit is not just to measure capacity,
but instead, to measure Equivalent Series Resistance
(ESR) and DC Resistance (DCR) in relation to capacitance. A perfect capacitor will
measure as an open circuit at DC, and will show less AC
resistance as the frequency across it increases. Most cheap cap
meters utilize this fact by measuring a cap's impedance
at a fixed frequency such as 1 KHz and translating the
reading to capacity. In reality, checking a cap at 1KHz
is pointless because in TVs, video monitors, and PWM power supplies,
frequencies of 100 KHz and higher are used. The
88 was the first device that would measure both DCR and ESR
currently available CapAnalyzer 88A Series II adds improvements such as DCR range to 500 ohms for testing smd tantalum caps, and additional features such as a battery-saving quick ESR test mode InstaESR that bypasses the DCR test for the quickest ESR-only test, and updated LED display drivers that increase accuracy and decrease battery drain.
ESR meters have their limitations; they don't check DCR
for leaky or shorted caps and you must discharge each cap
before testing, or risk damage to the meter. Their test
probes add their own capacitance, and readings vary
depending on the position that the probes are held. Also,
these meters usually don't use a frequency high enough to
isolate the specific capacitor to be tested.
uses a test frequency higher than any other DCR/ESR meter (over 100KHz),
automatically discharges the cap under test, checks DCR first (up to 500 ohms), then checks and
displays ESR on a 20 segment LED bar scale, and beeps
from one to five beeps depending on the ESR condition of
the cap. Both DCR and ESR measurements are made at levels that isolate the cap under test from the rest of the circuitry. Because it checks DCR first with its exclusive "DCR Set Alert", it will alert the
technician immediately if the cap or anything else
in that circuit is shorted or leaky, before it checks
ESR. Range covers just about any electrolytic or tantalum capacitor you will come across, from 0.47uF to 2200uF.
Be aware that there are many illegal knockoffs and look-alike meters trying to fool you, like the B+K Precision 881 and GME Technology 236, that hope to lure you into buying what you think is our CapAnalyzer
88A. These won't check tantalums in-circuit, and because of limited DCR range of only 30 ohms and lower-quality circuitry, you will never be 100% assured that you've found every leaky capacitor. The omission of the DCR set alert, special beryllium copper tipped tweezer one-handed probe and many other qualities that have made our made in USACapAnalyzer 88A the choice of over 50,000 technicians throught the world, should make your choice obvious. In fact, our CapAnalyzer 88A is the number one asked-for-by-name cap checker in the world; see the short list of major users (above left) that buy the CapAnalyzer
88A in large quantities for their technicians. Why? Because only the EDS-88A CapAnalyzer guarantees 100% accuracy.
88A includes a special beryllium copper tipped low-capacitance one-handed tweezer
test probe for accuracy and ease-of-use. Because it is
dual-microprocessor controlled, it has more features and is
much more accurate than other cap testers. A three-color
chart on the front panel shows typical ESR readings of
good and bad caps in relation to their capacitance. Portability and battery operation make it ideal for repairs on site, eliminating a double service call and valuable technical travel time. An AC adapter is availiable for continuous use on your bench.
