CAUTION Before switching on this instrument, make sure that the analyzer line volta ge
selector switch is set to the voltage of the power supply and th e c orrec t f us e i s
installed. Assure the supply voltage is in the specified range.
CAUTION If this product is to be energized via an autotransformer make sure the
common terminal is connected to the neutral (grounded side of the mains
supply).
