## Overview

The Atlas ESR70 by Peak is a compact, battery-powered capacitor analyzer designed for professionals seeking precise ESR and capacitance measurements. Featuring an enhanced 0.01 ohm resolution and a wide 0-40 ohm dynamic range, it supports capacitors from 1µF to 22,000µF, including motor and electrolytic types. Its unique audible alert system provides instant, intuitive feedback on capacitor condition, enabling efficient in-circuit testing without removal. Ideal for engineers and technicians aiming to diagnose capacitor health quickly and accurately.

## Description

PEAK Atlas ESR70 (ESR PLUS) (Equivalent Serial Resistance) Capacitor Analyzer with Audible Alert This new model features new features and enhanced measurement ranges, such as Audible Alerts. All measurements of the ESR are usually displayed on the display, of course, but the unit produces various tones depending on the ESR value. Also, the tone itself is amazingly comfortable whether it's a "bell-like" ping (some different types of ESR below a certain value) or a "Beep-Barp" type tone for ESRs that are likely to be too high. There is also a "lip" for peace of mind once the measurement begins and completes. The ESR measurement range has also been enhanced and doubles as a 0-40 ohm measurement at a low resolution of 0.01 ohm. This exceptional resolution is ideal for large capacitor ratings and can also be used to trace short circuits using Atlas ESR+ to find the exact area of the PCB with an invisible solder whisp. Measuring the ESR (Equivalent Serial Resistance) of a capacitor is a great indicator to show the state of the capacitor. Atlas ESR70 PLUS provides instant results. When the device is switched on, simply connect the probe to the capacitor, analysis will begin automatically. You can also use the Atlas ESR70 PLUS InCircuit, eliminating the hassle of removing capacitors. When testing out-circuit capacitors, the unit will also display capacitance

## Questions & Answers

**Q: What type of leads come with the unit, i. e. alligator/pin probe?**
A: Jack, if you wanted to use pin probes they would attach to the alligator clips.  The leads on the unit are about 20" long anyway.

**Q: I work on old Amps,  can it test 350 volt & 450 volt capacitors.this question is pertaining to the Atlas ESR 70**
A: As others have mentioned, it can test those capacitors if they are in their discharged state.The manufacturers specs say -  it can auto discharge up to +/- 50v  and for a cap that is less than 10uF the absolute maximum it can withstand is +/- 275v, over 10uF that is +/- 50v

**Q: Can this unit be used to test capacitors in circuit (without unsoldering)?**
A: Atlas ESR can be used in the circuit. For this reason, also be measured without removing the capacitor from the substrate. Of course, even if you test a capacitor is removed from the circuit, can be measured.

**Q: so it only checks capacitance of .1uf or higher?**
A: Its capacitance measurement range is 1uF to 22,000uF with 0.2uF accuracy.

操作ボタンはONとOFFの2個だけで操作も簡単。測定値は繰り返し精度も有り、信頼できる。音と表示のせいか、なぜか測定が楽しくなるテスターです。微小抵抗値測定器としても使える所が良い。ただ電源の12Ｖ電池の消耗が早いと感じるので星－1です。なので、電池ホルダーから線を外に引き出し、リチウムイオン充電池3本＋シリコンダイオード1個を直列に接続した電池ホルダーを外付け改造してしまいました。
