Analyse any type of capacitor from 1uF to 22000uF. Motor capacitors, smoothing capacitors, any dielectric type.

The Atlas ESR Plus provides all the functions of the popular ESR60 unit (pictured right) but with some exciting new features. In particular the ESR70 introduces new audible alerts (for various ESR levels) and a new improved measurement range (up to 40 ohms instead of 20 ohms). Measurements are made at the industry standard frequency of 100kHz. Probes are now removable, allowing 2mm compatible probes to be fitted

• Measure capacitance and ESR.
• Suitable for any capacitor type between 1uF and 22000uF including motor capacitors, smoothing capacitors, electrolytics, polypropylenes, in fact any dielectric type.
• Automatic analysis start when applying probes to capacitor.
• New enhanced dynamic range of 0.00 to 40.0 ohms.
• Audible alerts for various ESR levels.

• Supplied complete with 2mm male test leads and 2mm compatible gold plated crocs.
• Test leads are ultra-durable and 45cm (18") long with 2mm plugs.
• Enhanced software compensation of cable resistance.
• Complete with comprehensive user guide.
• Capacitor reference table included.
• Tests at the industry standard 100kHz. 
• Long life alkaline battery fitted.
• Just 100mm x 70mm x 20mm

This new model introduces new features including “Audible Alerts” and enhanced measurement range. Every measurement of ESR will be shown on the display as usual of course, but the unit will also produce a variety of tones depending on the value of ESR. And the tones themselves are surprising pleasant, including “Bell-like” pings (a couple of different types for ESR that is below certain values), 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.

The ESR measurement range has also been enhanced, now doubled, measuring from 0 to 40 ohms with a resolution as low as 0.01 ohms. This remarkably fine resolution is great for assessing large capacitors and even allows you to use the Atlas ESR+ for tracing short-circuits and finding the precise area of a PCB that has that invisible wisp of solder.

Great Service Aid
Measuring a capacitor's ESR (equivalent series resistance) is a great indicator of capacitor condition. The Atlas ESR PLUS 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 PLUS in-circuit, saving you the trouble of removing capacitors. When testing capacitors out-of-circuit, the unit will also display the capacitance.
