ATTENTION: Disconnect the speaker system from the amplifier before performing this test, otherwise you may damage the test meter.
•The impedance of the speaker downstream of the one being tested can be measured while the system is powered on by first disconnecting the captive screw connector from the speaker being tested and then connecting the test probes to the outer (LOOP) terminals of the connector, as shown below.
ATTENTION: Be certain to first disconnect the captive screw connector from the speaker being tested and test the outer (LOOP) terminals, otherwise you may damage the test meter.
