WARNING Product Grounding

The instrument is a Class 1 product and is provided with a grounding-type power cord set.
The instrument chassis and cover are connected to the instrument's electrical ground to
minimize shock hazards.

The ground pin of the cord set plug must be firmly connected to the electrical ground
(safety ground) of the terminal at the power outlet. Any interruption of the protective earth
(grounding) conductor or disconnection of the protective earth terminal will cause a
potential shock hazard that could result in personal injury or death.

Connect Power and I/O Cables
Connect the power cord, LAN, GPIB, RS232/485, or USB cable as desired.
The instrument's default measurement function is DC Voltage (DCV), with auto-ranging enabled.


Power Switch
Press the power switch in the lower left corner of the front panel. If the instrument does not turn on,
verify that the power cord is firmly connected, that the fuse is good, and that the line voltage selector
is set correctly, as described above. Also, make sure that the instrument is connected to an energized
power source.

To turn off the instrument, press and hold the power switch for about 500 ms. This prevents you from
accidentally turning off the instrument by brushing against the power switch.

NOTE If you turn off the instrument by disconnecting power (this is not recommended), the instrument
turns on as soon as you re-apply power. You will not need to press the power switch.
