## Overview

The Blue ESR Tester Kit is a professional-grade, DIY assembly ESR meter designed for precise measurement of capacitor equivalent series resistance above 1uF with ±0.01 ohm accuracy. Featuring a bright 0.5 inch blue LED display, non-polarized test leads with resistance compensation, and smart auto power-off, it operates reliably down to 5.5V battery voltage. Ideal for electronics diagnostics, battery health checks, and grounding compliance, this USA-made kit includes a 1-year warranty and advanced firmware for fault detection, making it a must-have tool for serious tech professionals and hobbyists.

## Description

Our Blue ESR Meter Kit 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 is 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. 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 assembly 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 from Anatek.

It took me a few hours to solder all the components onto the board, but I'm not really experienced with kits like these and I had fun doing it. In my opinion it is worth saving the 20 bucks to get the experience that comes with putting one of these together. The meter powered on first try and everything worked as expected. I haven't put the meter to use yet but I've read a lot of reviews around the internet with praise for this device's accuracy and reliability. The design seems to be vary good as it even has a built-in fault detection system which tells you which part of the circuit to look for problems in in the case of an error. A couple of things that could have been improved: Include instructions for how to use the included alligator clips if desired instead of the banana plugs. Some reference on the case for how to apply the sticker straight would have been helpful - for the mild OCD in everyone it would be appreciated. For beginners, it is disconcerting to have a component which looks a little different than the picture in the manual. Also for a beginner I would like to be assured whether the crystal is polarized so that I am not unsure about the orientation I should solder it in.
Review: Very useful tool, but difficult to assemble - I love to build kits. In the past I have built over 200 Heathkits successfully. This kit is a very difficult one to build because the board is so tightly packed with components. The assembly instructions are very basic. It requires a steady hand, a fine point soldering iron, and an illuminated magnifying light. It is nearly impossible to correct parts placement errors without severely damaging the very fine foil traces. I built 2 of these and both had problems due to my assembly. If you are an EXCELLENT kit builder, I say go for it. If you have any doubts, pay the extra $20 and get one that's assembled.

### ⭐⭐⭐⭐⭐ Well done!
*by J***S on September 29, 2015*

This took me an hour to assemble. I've been soldering for 20 years and am familiar with kit assembly, components, etc. It's not a race, though. Reference designators are clear and you shouldn't have much trouble matching components to locations. Parts are in baggies by type. I started with resistors. Check part counts and values. Double check your work as you go. It will save you time and aggravation. No parts were missing in my kit. The unit worked well when powered. The calibration instructions didn't come with mine. It is on Anatek's website, but I think they should have been included. Calibration is simple, though. This unit replaces an older unit I had bought years ago-mul3333. Anatek's unit is much better and works faster. It is also much more precise. ESR testers make quick work of finding bad capacitors and I highly recommend this one.
