Before Turning Power On
Using the Battery Pack
• For battery operation, use only the HIOKI Model 9780 Battery
Pack. We do not take any responsibility for accidents or
damage related to the use of any other batteries.
Using the AC Adapter
• Use only the supplied Model Z1005 AC Adapter. AC adapter
input voltage range is 100 V to 240 VAC at 50 Hz/60 Hz. To
avoid electrical hazards and damage to the instrument, do
not apply voltage outside of this range.
• Turn the instrument off before connecting the AC adapter to
the instrument and t
o AC power.
• To avoid electrical accidents and to maintain the safety spec-
ifications of this instrument, connect the power cord pro-
vided only to a 3-contact (two-conductor + ground) outlet.
• Use only the designated power cord with this instrument.
Use of other
power cords may cause fire.
• 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.
• Do not connect the supply voltage improperly. Doing so may damage
the instrument’s internal circuitry.
• Avoid using an uninterruptible power supply (UPS) or DC/AC inverter
with rectangular wave or pseudo-sine-wave output to power the instru-
ment. Doing so may damage the instrument.
• When the power is turned off, do not apply voltage or current to the
termina
ls. Doing so may damage the instrument.
• After use, always turn OFF the power.
• Brief power interruptions of 40 ms or less will not cause this instru-
ment to malfunction. However, Longer interruptions may cause the
instrume
nt to shut itself off, so consider local power conditions before
installing, as appropriate.
• To ensure that recording is not interrupted by power outages, you can
use the Z1005 AC Adapt
er and 9780 Battery Pack together.
