ESR70 – Atlas ESR PLUS



The Atlas ESR PLUS measures both the capacitance and Equivalent Series Resistance (ESR) of a capacitor. This model features a wider ESR measurement range and audible alerts too. The ESR is a great indicator of the capacitor’s condition, as a capacitor fails, it’s ESR rises. This advanced meter can measure ESR even in-circuit. It will measure capacitance too if the capacitor under test is out of circuit. Additionally, the ESR70 features audible alerts than gives you instant audible indication of the ESR across 3 thresholds allowing for easy analysis of multiple capacitors without the need to look at the display. A unique feature of the Atlas ESR is the ability to detect if the capacitor is charged, if the capacitor is charged then the Atlas ESR will gracefully discharge the capacitor using a constant power algorithm designed to prevent nasty discharge currents. The Atlas ESR will automatically detect when the test clips are applied to a capacitor and start it’s analysis, great when testing many capacitors. Capacitance measurement range from 1uF to 22,000uF, enhanced ESR measurement range from 0.01 Ohms to 40.0 Ohms. Minimum ESR resolution is 0.01 Ohms. Can also be used for short circuit tracing. ESR test frequency is industry standard at 100kHz. Supplied with removable gold plated croc clips. Compatible with standard 2mm connectors. Complete with battery, test leads, gold plated crocs and user guide with capacitor ESR reference chart.
