DANGER
This unit cannot be used on voltage lines of 600 Vrms. If the
voltage exceeds 600 VAC, there will be a short-circuit accident or
electrocution accident will result.
The maximum input voltage and current are 600 Vrms, 60 Arms. Do
not exceed the maximum input voltage and current. Doing so can
damage the unit or cause a serious accident.
The maximum rated voltage between input terminals and ground is
600 Vrms. Attempting to measure voltages exceeding 600 Vrms
with respect to ground could damage the instrument and result in
personal injury.
Always connect the powermeter input to the secondary side of the
breaker. On the secondary side of a breaker, even if the lines are
shorted the breaker can trip and prevent an accident. On the
primary side, however, the current capacity may be large, and in
the event of a short-circuit there may be a serious accident.
WARNING
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. If an attempt is made to use an improper
supply voltage, there is danger of damage to this unit and of life-
threatening risk to the operator.
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 voltage input terminals or current input
terminals correctly. Measurement which is attempted with the
wiring connected incorrectly may cause damage to the unit or a
short-circuit.
Since the power switch is of a micro gap construction, always use
near an outlet. When not in use and when connecting a device to
be measured, make sure that the power cord is unplugged, or any
other means so that the unit is cut off from the power.
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.
Do not remove the case of the unit. There are components inside
carrying high voltages or becoming hot, and this could cause an
electric shock accident.
Do not use the unit where it may be exposed to corrosive or
explosive gases. The unit may be damaged, or explosion may
occur.
Notes on Use
In order to ensure safe operation and to obtain maximum performance from
the unit, observe the cautions listed below.
