The 1109S has a capacitor in series with the OUTPUT terminal. This
OUTPUT terminal is useful for measuring the AC component only of
a DC coupled Low Frequency Output in TV sets, audio equipment
circuits, etc. by blocking the DC component.
⑴ Insert the red test lead into the OUTPUT terminal and the black test
lead into the -COM terminal.
⑵ Make Low Frequency Output measurements in accordance with the
instructions given for AC voltage measurements.

# WARNING
Make sure that the test leads are securely connected to the circuit.
If the test prods are disconnected inadvertently, a high voltage
may develope in the circuit.
# WARNING
Never apply voltage to the current ranges. The fuse could blow or
the instrument get damaged.
Especially when a voltage higher than 250V is applied accidentally,
the fuse may not protect the circuit.
