2-7 Connecting the Power Supply
Supply power to this equipment through the AC adapter that comes with this equipment.
* The amplifier does not have a power switch. Never turn power on or off by connecting or
disconnecting the I/O cable. It could damage not only the amplifier and AC adapter but also other
devices connected.
Check the supply voltage before connecting the AC adapter to the AC power source.
The operating voltage of the AC adapter is 100 to 240 VAC.
* If the supply voltage is out of the above voltage range or each terminal voltage of the power supply has
higher potential than the supply voltage against the ground, never connect it to this equipment. It could
cause failure or accidents.
Check the supply voltage as follows.
①
Using a multimeter, measure the voltage between the terminals of the AC power outlet to make sure that it
is 100 to 240 VAC.
②
Using a multimeter, measure the voltage between each terminal of the AC power outlet and the ground to
make sure that one is 0 V and the other is 100 to 240 V.
③
In the field where equipment that generates noise such as an induction motor or electric welder is used, the
power condition is expected to be bad with much noise. Take measures against noise by using
commercially available isolation transformer or noise cut transformer.
Warm up the system for 30 minutes or more after power on. Insufficient warmup could make measurements
unstable.
