2.4 Turning the Power On and Off
Using the AC Adapter
Before turning the instrument on, make sure the supply volt-
age matches that indicated on its power connector. Connec-
tion to an improper supply voltage may damage the
instrument and present an electrical hazard.

Rated supply voltage is 100 to 240 VAC
(Voltage fluctuations of ±10% from the rated supply voltage
are taken into account.)

Rated supply frequency is 50 or 60 Hz.

Turn the power

switch on ( ).
If the " " indicator is not displayed, the instrument is not being powered
from the AC line. In this state, the battery charge will be depleted if measuring
for a long time, and measurement may be interrupted. Verify that the AC
adapter is securely connected to an AC power source and to the instrument.
Turning Power On
Turn the power

switch off ( ).
The installed battery pack is charged whenever the AC adapt-
er is plugged into a power outlet, even when the Memory
HiLogger is off. In addition, providing there is some remaining
battery charge, waveform data and the setting configuration
are memorized whenever the Memory HiLogger is turned off,
so that when the Memory HiLogger is turned back on, the
same operating state is displayed.
Verify that the instrument and peripheral devices
are correctly connected.
