Measuring a capacitor's ESR is a great indicator of capacitor condition. The
Atlas ESR+ offers instant results, just connect the probes and press test.
Innovative audible alerts give you an instant feedback of the measurement
results with further detail shown on the screen.
And the tones themselves are surprisingly pleasant, including Bell-like pings
and also a Beep-Barp type tone for ESR that is likely to be too high. There is
also a reassuring Blip when the measurement has started and completed.
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. This clever instrument is a great way to check the
physical condition of a wide range of capacitors. Elevated ESR is a sure
indicator that the capacitor is failing and likely to dissipate heat and perform
less like a capacitor and more like a resistor at high ripple currents.
It can measure and compensate for the effects of measuring ESR in-circuit
too, it also knows that you do not want to be hassled with capacitor polarity,
just connect any way round. It's designed with the real world in mind. Some
capacitors can be charged up, but the Atlas ESR+ does not mind. If your
capacitor is charged, the unit will automatically carry out a controlled
discharge procedure before measuring the capacitance and ESR.
