3.1 Preparation before Test
(1) Before plugging in the power cord, make sure the power switch is off
and the voltage selector on the rear panel meets the required
voltage.
(2) If there is a need to change the voltage, ensure the fuse used
matches the voltage selected. See section 1.5 Fuse for the
specification.
WARNING
It is required to remove the power cord when replacing
the fuse or changing the input voltage to avoid the
hazard of electric shock.
