For the T921, use the channel 1 control settings and
procedures .
1 .
Check that the Power Input Voltage Selector switch
and the HI-LO Range Selector switch
on
the bottom
of the
cabinet (T921 and T922) are set for your power input
voltage . In the United States, the Power Input Voltage
Selector switch is normally set for 120 V and the HI-LO
Range Selector switch is normally set for HI atthefactory .
In Europe, the Power Input Voltage Selector switch is
normally set for 240 V and the HI-LO Range
Selector is
normally set for LO . Only qualified service personnel
should change the Power Input Voltage Selector Switch to
a different voltage range setting .
2 .

If
the 120 V/240 V and HI/LO switches
are properly
set, connect
the power cord plug to the power
source and
turn the
instrument on, connect test equipment
to an
appropriate power
source and turn it on . Set the trigger
MODE to AUTO, and
SOURCE to INT .
