Line Voltage Selector

Set the line voltage selector to the setting corresponding to the power source used. Access to
this switch is provided through a hole in the left-front bottom cover. Refer to Figure 2-1 for an
illustration of the line voltage selector.
WARNING
Before turning this instrument on, make sure it is grounded through the

of the protective earth terminal, can result in personal injury.
CAUTION
Before turning this instrument on, make sure the line voltage selector is set to
the voltage of the ac power source.
115 V position for 90 to 132 Vac line input voltages
230 V position for 198 to 264 Vac line input voltages
Failure to set the ac power input to the correct voltage could cause one of two
things to happen when power is applied.
If the switch is set to 115 V and the instrument is connected to 230 V, the
fuse will blow.
If the switch is set to 230 V and the instrument is connected to 115 V, the
instrument will not turn on and the VOLT
