The **Peak Atlas ESR70** is a specialized instrument designed for measuring the Equivalent Series Resistance (ESR) and capacitance of capacitors, both in and out of circuit. It is widely used by electronics professionals and hobbyists for diagnosing capacitor health in power supplies, amplifiers, and other electronic devices.

### **Key Specifications:**

- **ESR Measurement Range:** 0.00Ω to 40.0Ω with a resolution of 0.01Ω.

- **Capacitance Measurement Range:** 0.3µF to 90,000µF.

- **Test Frequency:** Operates between 48kHz and 104kHz, ensuring precise ESR readings.

- **Power Source:** Runs on a single AAA battery, providing approximately 1,500 operations per battery cycle.

### **Notable Features:**

- **Automatic Analysis:** The device begins testing as soon as a component is connected, simplifying the measurement process.

- **In-Circuit Testing:** ESR can be measured without removing capacitors from the circuit, making diagnostics faster and more efficient.

- **Audible Alerts:** Sound notifications provide real-time feedback during testing.

- **Enhanced Display:** The LCD features improved visibility with better contrast and backlighting.

- **Rapid Capacitance Measurement:** For capacitors over 125µF, the device applies a higher test current (20mA) to speed up readings.

The **Peak Atlas ESR70** is a user-friendly and reliable tool, ideal for those involved in electronic testing and repair.
