Great Service Aid
Measuring a capacitor's ESR (equivalent series resistance) is a great indicator of capacitor condition. The Atlas ESR offers instant results, if the instrument is switched on then just connect the probes to your capacitor and the analysis starts automatically. You can even use the Atlas ESR in-circuit, saving you the trouble of removing capacitors. When testing capacitors out-of-circuit, the unit will also display the capacitance.
