3. PRECAUTIONS BEFORE OPERATING THE OSCILLOSCOPE
3.1 Unpacking the Oscilloscope
The oscilloscope is shipped from the factory after being fully inspected and tested. Upon receiving the instrument, immediately unpack
and inspect it for any damages that might have been sustained during transportation. If any sign of damage is found, immediately notify the
bearer and/or the dealer.
3.2 Checking the Line Voltage
These oscilloscopes will operate on any one of the line voltage shown in the table below, by inserting the line voltage selector plug in the
corresponding position on the rear panel. Before connecting the power plug to an AC line outlet, make sure the voltage selector is set to the
correct position corresponding to the line voltage. Note the oscilloscope may be damaged if it is connected to the wrong AC line voltage.
WARNING.
To avoid electrical shock the power cord protective grounding
conductor must be connected to ground.
