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.
To avoid electrical accidents and to maintain the safety
specifications of this instrument, connect the power cord provided
only to a 3-contact (two-con ground) outlet.
The power switch has a microgap construction, and it is therefore
essential to use it close to a power outlet. When the unit is not in
use, and while making connections to the circuit being tested, isolate
the unit electrically from the power supply, for example by removing
the power cord plug from the outlet.
CAUTION
・ Should the unit emit smoke, or a strange smell or strange sound,
immediately stop testing operations, power the unit off, and remove the
power cord from the outlet, shut off the circuit being tested,
disconnect the unit, and consult your HIOKI representative. Continued
use of the unit could lead to fire or electric shock accidents.
・ When the power is turned off, do not apply voltage or current to the
voltage input terminal, current input terminal, or clamp sensor. Doing
so may damage the unit.
NOTE
3.3 Powering On
1. Confirm that the voltage of the power supply being used matches the
supply voltage indicated on the rear panel of the unit.
2. Confirm that the power switch on the front panel is off.
3. Connect the supplied power cord to the AC inlet on the rear pane.
4. Connect the power cord to a grounded three-pin outlet. If no grounded
outlet is available, use the supplied ground adapter.
5. Turn on the power switch on the front panel.
6. The unit starts the self-test. It is completed after about 10 seconds.
Self-Test
In the self test, the following tests are carried out, then after about 10
seconds the measurement screen automatically appears.
・
Unit version
・
Installed options
・
RAM check
If there is a problem in the settings, this screen remains displayed and the
unit stops. If this happens again after powering off and on, the unit has
developed a fault. Stop measurement, and shut off the line being measured,
then power off the unit. Disconnect the test wiring and the power cord.
