Suitable for use with any capacitor type from 0.3μF to 90,000μF, including motor capacitors, smoothing capacitors, electrolytics, polypropylene, and any other dielectric capacitor type, this unique instrument identifies components and gives the user detailed information about the capacitors' status.
The Peak Atlas ESR Gold is an enhanced version of the previous Peak Atlas ESR Plus. It provides instant measurement of a capacitor's ESR and its capacitance value. Using the supplied gold-plated probes (removable), the Peak Atlas ESR Gold can measure ESR down to a resolution of 0.01Ω, up to 40Ω. It can even measure ESR for capacitors that are in-circuit. Probes are removable, allowing 2mm compatible probes to be fitted. Audible alerts are produced for various ESR levels, allowing you to perform many tests in succession without having to look at the display.
To use, connect the supplied test leads directly to the component in any configuration. The ESR70 will then automatically identify the type of capacitor connected (and is suitable even for in-circuit capacitors), measure the equivalent series resistance (ESR) and give detailed information on capacitor status.
