Introduction
The
is an advanced instrument designed specifically for the
analysis of capacitor equivalent series resistance (in
out of circuit).
In addition it will, where possible, display the capacitance of the
device under test.
•
ESR measurement range 0 to 20 (40 for ESR70).
•
ESR resolution as low as 0.01 .
•
Capacitance range 1µF to 22000µF.
•
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.
