Peak Atlas ESR PLUS Low Resistance and Capacitance Meter

The new Peak ESR70 Atlas ESR PLUS Capacitor Analyzer introduces new features including "Audible Alerts" and enhanced measurement range. Every measurement of the ESR (equivalent series resistance) tester will be shown on the display as usual, but this unit will also produce a variety of tones depending on the ESR value, and the tones themselves are surprising pleasant, including Bell-like dings, a "Beep-Barp" tone for ESR that is likely to be too high, and also a reassuring "Blip" when the measurement has started and completed.

The Peak Atlas ESR70 measurement range has doubled, measuring from 0 to 40 ohms with a resolution as low as 0.01 ohms. This amazingly fine resolution is great for assessing large capacitors and will allow you to use the Peak Atlas ESR+ for tracing short-circuits, running meter tests, testing meter circuits and finding the precise area of a PCB.

Measuring a capacitor's equivalent series resistance (ESR) is a great indicator of the condition of a capacitor. Unlike other capacitor meters, the Atlas ESR capacitor meter offers instantaneous results. If the instrument is switched on you simply connect the probes to your capacitor and the analysis will begin automatically. You can use the Atlas ESR PLUS in-circuit, which will save you the trouble of removing capacitors. When you test capacitors out-of-circuit, the ESR+ will also display the capacitance. To analyze your network cables, we recommend the Peak Atlas UTP05.


Features

  • Simple capacitor ESR meter and tester
  • ESR resolution as low as 0.01 Ohm
  • Audible alerts
  • Built-in protection circuitry means risk of damage to the unit due to residual charge is greatly reduced
  • Integrated controlled discharge circuitry reduces the need to manually discharge capacitors before test
  • Use in or out of circuit for ESR measurement and testing
  • Automatic and manual power-off
  • Can also be used for low-Ohms resistance checking

What's Included

  • Peak Atlas ESR+ with attached 45 cm silicone test leads

    I used it to test a box of caps that I bought at a Ham fest, it did a great job and they were all good. Thanks

    The Peak Atlas ESR70 meter does what it is supposed to do, and displays a value within seconds. In and out of circuit, it's a fabulous tool and "must have" for any bench tech.

    Great price, turnaround time and product. Keep up the good work.

    At first glance, I immediately noticed a potential upgrade to the ESR70 -
    DVM type connectors on the unit and a probe storage area in a case that protects the display/keypad. An experienced electrical guy, like myself, should be able to setup something handy to fulfill these needs.

    Excellent tool like any of the tools from Peak. Works very well, and fast. This review is aimed more at Velleman than the tool itself. I recently walked in to the Velleman store in Ft.Worth unaware that they are an online only store, the staff really went out of their way to get this tool in my hands on the spot. Thanks guys, I really appreciate what you did as I was short on time!!

    We have had this just a couple of days at this writing but so far, it has been handy and helpful. I like its quick response on measurements and gives the information you need. Compact and easy to use. Does what it says it will do. I had to turn off the audible beeps. They were worrisome to me. Overall, great for measuring esr and capacitance.

    Works as advertised, very straight forward. Wish the leads were interchangeable with other tips rather than just alligator clips.

    I should have purchased one of these a long time ago. I have tested this unit against known good and bad caps and it works as advertised.
    The manual is straight forward easy to understand. I would recommend the ESR70. I do however wish it came with a storage pouch or case.

    Have had it for a week. Still testing. But so far so good. Like that it tests at 100kHz.

    Ability to read capacitance directly as well as ESR is a big plus. So easy to use. Found bad power supply cap in an old analog TV in 30 seconds. Handy addition to my workbench. One heck of an instrument in a 3.5 ounce package. Wish it also came with tweezer probes.

  12. Great ESR device review by Chuck on 6/4/2016

    I needed an ESR meter to check capacitors in an old device. This meter is simple to use and very intuitive. The manual is well presented and straight forward, allowing me to get to measuring the wellness of the new and old capacitors I was dealing with. The device first discharges caps, then gives capacitance and resistance readings through the display and with audio beeps. There is a table for guidance on the readings, in the manual. It was so smooth and painless to operate, I want to keep checking many more capacitors, as the process is quite gratifying and efficient.
