## Overview

The Blue ESR Tester is a fully assembled, high-precision LCR meter designed for in-circuit ESR measurement of electrolytic capacitors >1uF. Featuring ±0.01 ohm accuracy, a bright 0.5 inch blue LED display, and automatic power-off to conserve battery, it supports advanced diagnostics including battery health and PCB fault detection. Made in the USA with a 1-year warranty, it’s the go-to tool for professional amp repair, electronics troubleshooting, and quality assurance.

## Description

Our Blue ESR Meter has been very popular since 2007. This is the latest Bob Parker design and successor to the famous Dick Smith MKII ESR and Low Ohms Meter. This handy and affordable ESR meter measures capacitor equivalent series resistance (ESR) for capacitors >1uF and up to 450V. ESR is a very important quality and performance characteristic of capacitors greater than 1 uF. This meter makes measurements which are often impossible to check with capacitance meters. It also can be used to assess health for LV alkaline/rechargeable batteries, find shorts on PCBs, inductive coil shorts and for assessing incoming quality assurance of components and can also be used to test the low resistance grounding of ANSI/ESD S20.20, ANSI/ESD S6.1, ESD TR20.20 and compliance verification for grounding systems. Includes quality test leads with banana jacks, basic alligator clips, easy-access battery compartment and on-board diagnostics to detect errors. You can add the optional croc clips and/or probes or use your own. This has the MkII firmware, Bob's latest version developed over many years. It can accurately test ESR down to an internal battery voltage of 5.5 volts. It has a full 1yr warranty on parts and assembly from Anatek.

Review: Must have for amp repairs. - Saw Uncle Doug using this on YouTube and thought I should get this as I had an old Fender amp I was restoring. This is the tool to have for checking old electrolytic capacitors.
Review: Excellent test equipment - I am heavily involved with repairing and building vacuum tube amplifiers and use this piece of test equipment regularly. Great device!

## Questions & Answers

**Q: Can i test esr of an 18650 li ion with this?**
A: I believe that it can. The manufacturer has a video on youtube demonstrating tests of sone batteries.

**Q: does it consume alot of the battery power?**
A: I purchased my esr meter about a year ago and have used it from time to time and have yet to replace the battery.  My guess is that battery usage would be similar to that of a typical ohm meter.  I am extremely happy with the purchase.  It quickly determines the good or bad status of caps and would recommend its purchase.  It will be worth the price the first time you diagnose a clean looking cap that is in fact internally damaged.

**Q: I see it has an upper limit of 450volts. If you attempt to measure measure anything higher then 450v what happens? Does damage the meter? Not accurate**
A: The 450V refers to a test capacitor's voltage rating, not the voltage the unit can withstand. This unit can test capacitors in circuit, but must be fully discharged before testing or damage will occur to the meter.

**Q: At what frequency does this meter test?**
A: I believe 100 Khz...
