[Peter Demchenko] wanted to use a low power TS555 in an ESR meter design. The problem is, he needed to handle significant current sink requirements for cases where the capacitor under test had a ...

Capacitance and ESR are not the only things that can indicate a failed capacitor. Fig. 1: Note the “domed” tops of these “bad” capacitors. Fig. 1 shows a capacitor bank in a QSC MX1500A amplifier.

Even if you have no need for an ESR meter, [W2AEW]’s video below is a solid introduction to how ESR is determined. The circuit itself comes from EEVBlog forum user [Jay-Diddy_B] and is about as ...

The Capacitor Wizard measures ESR with the capacitor “in-circuit.” Its ESR meter’s low input impedance, simplicity of use and real-time measurements still make it the fastest and most reliable ESR ...

WATERLOO, Ontario , May 19, 2016 /PRNewswire/ — A new model in the Smart Tweezers line of handheld LCR- and ESR-meters now has a Bluetooth enabled connection. The ST5S-BT allows users to remotely ...

Designed to test components at frequencies up to 10 kHz, the Model 885 Synthesized In-Circuit LCR/ESR handheld meter is claimed as the most accurate meter on the market. The battery-powered device ...

The meter includes IEEE-488, RS-232 and handler interfaces, all standard. Other features include setup storage of 30 test programs, load correction, constant voltage mode, and dc voltage bias.
