                     IN-CIRCUIT CAPACITOR ESR METER   What does “ESR” mean?    An ideal  capacitor only  has capacitance properties. While a real capacitor can be viewed as a resistor connected with an ideal capacitor in series. Since this kind of resistor does not exist physically, we call it Equivalent series resistance or “ESR”. It mainly caused by Cap’s down-lead connection and electrolyte drying gradually. When a capacitor degrades its ESR value will go up.    Why use ESR Capacitor Meter?     Many years in my repair career, I can not remember how many bad capacitors were detected by my ESR Meter in circuit. Every time  when I   was frustrated with my defective appliance, it is  the ESR Capacitor Meter that solved the problem for many times. You can understand easily.  If a capacitor is open or shorted, it is easy to detect by using a Multimeter. But in the most cases, the capacitors are neither open nor shorted.  They can almost keep as the same value as the good ones have, but they do  not  work  in  circuits  anymore.  In this case, it is very  hard to find a bad capacitor with Multimeter or even a LCR meter. But if you useCapacitor ESR Meter, you will see significant changes for those bad capacitors  which will tell no difference when you use other kind of meters.    How to use ESR Capacitor Meter?    Before  testing,  the  capacitor  should  be discharged! Then shorted the two probes,  turn the adjust  knob to ge t zero  reading.  Our  Meter is Non – polarity, you can touch capacitor two ends at will. The ESR value depends  on the capacitor  value  and  voltage  rating.  But  generally  speaking, if the “ESR” is less than one ohm, the Cap is good, if big than ten Ohms, the  Cap  is  bad.  We  have detailed reference data in our instruction  manual. And furthermore, you do not need to remove the capacitor from  circuits.  The  reason f or  this f unction  is  that  the  output test signal of ESR meter is only 16mvp-p and it will not active any solid devices.  In  addition,  our  ESR  Meter  can  also be used as a low ohms measurement meter, its accuracy is 0.1 ohm. Since a capacitor’s ESR  value  is  usually much lower than 10 ohms, the components parallel with the capacitor under testing will not effect the ESR reading and thanks for this feature that enables ESR Meter to be used in circuit.   Who will Benefit most from using ESR Capacitor Meter ?    Many Occupations can benefit from using ESR Capacitor Meter. Such  as  LCD  and  Plasma TV repair, digital Camcorder and camera,computer Motherboard, switching power supplies, audio amplifiers, medical electronics, electric motor and etc.    Features of Capacitor Esr Meter    There  is  a  high  voltage  protection,  in case you foget to discharge the cap before testing. It can measure  the  inner  resistance  of the  batteries  directely.  This is a easy and reliable way to check the batteries. Auto power off , if there is no activity, makes your batteries last longer.Low battery voltage reminder. it uses 4 "AA" size batteries.     Specification       ESR Range:             0 -22 Ohms expanded Scale.           Output test signal:   100KHz sine wave        Output voltage:        16mvp-p         Power consumption: 72mW      Battery:                    4AA" size (6V)              Dimensions:             142 X 82 X 50 (mm)         Weight :                    0.21Kg(not including batteries)       PACKAGE CONTENT:    (1)  In-circuit Capacitor ESR Meter                                              (2) Test leads                                              (3) Operating manual(English/French)                                              (4) Data sheet                                              (5)Free Batteries                                                                                Find bad Cap quickly and reliably–In circuit!                                                      Check surface mount Caps without removing!                                            Portable Model, it is easy to carry out for Service!                                     Auto power off, makes your batteries last longer
