In order to prevent electric shock and short-circuit accidents, shut off
the power to the line to be measured before connecting the direct
connection voltage and current cables to the terminals.
Be sure to connect the input terminal, SENSE, or SOURCE terminals
correctly. Measurement which is attempted with the wiring connected
incorrectly may cause damage to the unit or a short-circuit.
Before turning on the power, make sure that the voltage of the power
supply being used matches the supply voltage indicated on the rear
panel of the unit.
The unit is constructed so as to be connected to a ground line via a
three-core power cord that is supplied with the unit.
In order to avoid electric shock, connect the unit to a properly grounded
(3-pin) outlet using the power cord provided. In addition, if using a
ground adapter, be absolutely sure to connect the green ground wire
which protrudes from the adapter to a ground line.
In order to avoid electric shock, if not connecting the unit to a properly
grounded (3-pin) outlet using the power cord provided, be sure to
connect the ground terminal to a proper ground.
The maximum permissible input is mentioned on specifictioins. Do not
measure voltage in excess of these limitations, as doing so may damage
the unit or cause an accident that might result in infuty or death.

・To avoid damage to the unit, do not input a voltage or current exceeding the
rated maximum to the external input terminals.
・To avoid damage to the unit, do not input a voltge or current exceeding the
rated to the output terminal.
・To avoid damage to the unit, do not subject the equipment to vibrations or
shocks during transport or handling. Be especially careful to avoid dropping
the equipment.
・Before using the unit, make sure that the sheathing on the probes is not
damaged and that no bare wire is exposed. If there is damage, using the
unit could cause electric shock. Replace the probe with the specified 9287.
・The unit should always be operated indoors in a range from 0℃ to 40℃ and
80% RH or less. Do not use the unit in direct sunlight, dusty conditions, or in
the presence of corrosive gases.
・Do not measure the voltage applied point. Particularly, the 3227 would be
damaged by induced voltage when measuring soon after the temperature
rise test or the pressure test of the trans or the motor.
