2.4 Powering On
────────────────────────────────────────────────────
WARNING
Before turning on the power, make sure that the voltage of the power
supply being used matches the supply voltage indicated on the AC
power inlet 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.
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.
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
･ When the power is turned off, do not apply voltage or current to the
voltage input terminals and the current input terminals. Doing so may
damage the unit.
･ 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.
NOTE
2.4 Powering On
Before measuring, please perform a warm-up at least for 30 minutes after the
power is turned on.
1. Make sure that the voltage of the power supply being used matches the
supply voltage indicated on the rear panel. (power supply voltage 100 V to
240 V)
2. Confirm the power switch on the front panel is OFF.
3. Connect the power cord supplied to AC inlet on the rear panel.
4. Plug the power cord into a properly grounded (3-pin) outlet that has a safety
grounded terminal.
5. Turn the power switch on.
6. All Indicators on the front panel are displayed and the self testing start.
Refer to Section 2.5, "Self Test" for details. This test ends about for 10
seconds.
