Connecting Mains Supply Voltage
Before plugging the unit in for the first time, it is a good idea to verify
that the power supply line voltage selection is correct. The units are
configured at the factory for the expected voltage at their intended
destination, so usually the voltage will be correct unless the unit has
been transported into another area.
The supply voltage indicator is located on the rear panel of the
instrument next to the power plug. A small white plastic indicator tip
identifies the line voltage setting as 100V, 120V, 230V, or 240 V.
The following diagram shows the location of the voltage indicators:
In one of the holes should be a small white plastic indicator tip
showing which line voltage is currently selected. If the selected voltage
is not the same as the line voltage in your area, see Appendix D for
instructions on changing the line voltage selection.
Once the line voltage selection is correct, connect the line cord from
the power outlet to the power cord connector and move the power
switch to the ‘On’ position (marked ‘1’).
