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.
Important: To minimise risk of damage to the unit, make sure that the
Atlas ESR has completed any previous analysis before attaching the test
probes to the capacitor. This ensures that the built-in protection circuit is
ready for any charge that may be present on the capacitor.
The Atlas ESR must first be switched
on by briefly pressing the on-test
button.
The unit will start a component analysis
when it detects that the open circuit
probes have been applied to a
component or when on-test button is
re-pressed.
If the capacitor is charged (<50V), the
Atlas ESR will attempt to discharge the
capacitor while showing the progress of
the procedure:
If the Atlas ESR cannot recognise the
component connected to the test probes,
or the capacitance is out of range, the
following message may be displayed:
