NessElectronics, Since 1964

This listing is for the Capacitor Wizard ESR Meter & the Cap Saver Kit.

From the one of the most trusted names for electronics on eBay, nesselectronics. We have been in business since 1964, selling on eBay for over 13 years. Check our feedback rating, we want to add you to our ever growing list of satisfied buyers! This tester can test capacitors 1uf and up in circuit. (Unit needs to be powered off and capacitors discharged). THIS LISTING INCLUDES THE CapSVR! To protect your Cap Wizard from charged capacitors. (The Cap Saver will need to be installed, instructions included). See details below:

In-Circuit ESR Meter

Since it's design in 1995 by Doug Jones, the Capacitor Wizard® has earned the respect of customers and the professional electronic service industry. Measuring ESR In-circuit can be tricky. We know how to do it and have been doing it for 20+ years. The Capacitor Wizard® ESR meter's speed, reliability and ease of use have made it the number one choice of electronic technicians.

Time Tested Design

Over the last 20+ years many ESR meters have come and gone yet the Capacitor Wizard® is still around. Why? It's low input impedance, simplicity of use and instant real time measurements still make it the FASTEST and most reliable ESR analyzer made today! The Capacitor Wizard® has become the "GOLD STANDARD" by which all other capacitor analyzers are compared! It has withstood the "test of time".

Best ESR Meter?

Our customers think so. Ask one. Speed, ease of use, proven track record, reliability, loud "part GOOD" beeper, long sharp needle point probes, real time measurements, unparalleled factory support are some of the features that make the Capacitor Wizard® the best ESR meter made today. Why settle for less? You're a pro and really need the very best!

CAPSVR

This listing includes the CAPSVR circuit, this will need to be installed in your Capacitor Wizard. (You will need to install this circuit in the device). Protect your meter from charged capacitors that you forgot to discharge before testing.

What is ESR? ESR is the abbreviation for “Equivalent Series Resistance”, sometimes referred to as “Effective Series Resistance”. ESR is a DYNAMIC (AC) property of a capacitor and cannot be measured with a DC ohm meter. ESR can be considered to be the total series NON-REACTIVE AC resistance of a capacitor. ESR includes the DC resistance of the leads, DC resistance of the connections to the dielectric, capacitor plate resistance, and the IN-PHASE AC resistance of the dielectric material. The combination of components that make up ESR are symbolized by a resistor in series with a capacitor as shown. The series resistor in the symbolic representation of “ESR” does not exist as a physical entity. Direct measurements across the ESR resistor are not possible! The Capacitor Wizard® overcomes this limitation by measuring only the NON-REACTIVE AC resistance(ESR).
