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:
• ESR measurement range 0 to 20Ω (40Ω for ESR70).
• ESR resolution as low as 0.01Ω.
• Capacitance range 1µF to 22,000µF.
• Can be used for low-ohms resistance checking too.
• Integrated controlled discharge circuitry reduces the need
for the user to manually discharge capacitors before test.*
• Use in or out of circuit for ESR and low-ohms resistance
measurement.
• The ESR70 features audible alerts for quick user-feedback
of ESR test status.
• Automatic analysis start when component is detected.
• Automatic and manual power-off.
* Note:
The discharge circuitry exists to ensure that a charged capacitor
is less likely to damage the unit. For example, if the capacitor
under test has a potential of a few tens of volts across it, the
charge is removed automatically. It is the user’s responsibility
to ensure that any dangerously
charged capacitors are safely
discharged before connection to the unit.
