DANGER
Always connect the voltage cable to the secondary
side of a 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.
This unit cannot be used on voltage lines of 250
Vrms. If the voltage exceeds 250 VAC, there will be
a short-circuit accident or electrocution accident
will result.
WARNING
In order to prevent an electrical accident, do not
make any connections while the power supply or
the device to be measured is on. Turn off the

The power supply voltage for this unit is switchable.
To avoid electrical accidents, check that the voltage
selector is set correctly for the supply voltage you
