Page 3: Introduction
ESR60/ESR70 User Guide April 2012 – Rev 8 Introduction The Atlas ESR is an advanced instrument designed specifically for the analysis of capacitor equivalent series resistance (in or out of circuit). In addition it will, where possible, display the capacitance of the device under test. Summary Features: •... -
Page 4: Safety Considerations
ESR60/ESR70 User Guide April 2012 – Rev 8 Safety Considerations WARNING: This instrument must NEVER be connected to powered equipment/components. It is the user’s responsibility to ensure that any dangerously charged capacitors are safely discharged before connection to the unit. To allow the self-protection mechanism to function, always ensure that the Atlas ESR has completed any analysis before connecting the test probes to a component. -
Page 5: Notes On Esr
ESR60/ESR70 User Guide April 2012 – Rev 8 Notes on ESR ESR (Equivalent Series Resistance), as it’s acronym implies, is the value of resistance that is effectively in series with an ideal capacitor. No capacitor is ideal of course, the detailed equivalent circuit of a typical capacitor is very complex. -
Page 6: Analysing Capacitors
April 2012 – Rev 8 Analysing Capacitors The Peak Atlas ESR is designed to analyse capacitor ESR in or out of circuit. The two test probes can be connected to the component any way around. Remember though that in-circuit testing can result in less accurate readings. - Page 7 ESR60/ESR70 User Guide April 2012 – Rev 8 Analysing Capacitors continued The ESR analysis typically takes under 2 seconds to complete, followed by up to around 10 seconds for the capacitance measurement (depending on the characteristics of the capacitor). As soon as a valid ESR reading has Measuring C...

Page 9: Typical Values Of Esr
ESR60/ESR70 User Guide April 2012 – Rev 8 Typical Values of ESR It is not possible to provide a definitive rule for values of ESR that are acceptable for all situations. The expected value of ESR largely depends on the capacitance value and the voltage rating of the capacitor but also depends on temperature ratings and other factors. -
Page 10: Audible Alerts
ESR60/ESR70 User Guide April 2012 – Rev 8 Audible Alerts (Model ESR70 only) The ESR70 unit can produce audible tones to assist the user. The various tones are summarised below: Condition / Operation Sound Type Start Analysis Short Blip End Analysis Short Blip Measured ESR >... -
Page 11: Probe Compensation
ESR60/ESR70 User Guide April 2012 – Rev 8 Probe Compensation To ensure good repeatable readings, particularly for low values of ESR, it may be necessary to occasionally perform a simple Probe Compensation procedure. This procedure is easiest to perform with the gold plated croc clips fitted. 1. -
Page 12: Care Of Your Atlas Esr
The Atlas ESR will not continue to operate if a low battery condition is encountered. New batteries can be purchased from many retailers and directly from Peak Electronic Design Ltd or an authorised agent. Battery types: Suitable battery types include 23A, V23A, GP23A, MN21 or a good quality 12V alkaline equivalent as used in many test instruments and automotive remote key fobs. -
