Operating Precautions
Shipping precautions
Hioki disclaims responsibility for any direct or indirect damages that may occur when this instrument
has been combined with other devices by a systems integrator prior to sale, or when it is resold.
Handling the Instrument
This instrument may cause interference if used in residential areas. Such use must be avoided un
-
less the user takes special measures to reduce electromagnetic emissions to prevent interference
to the reception of radio and television broadcasts.
DANGER
To avoid electric shock, do not remove the instrument’s case. The internal com-
ponents of the instrument carry high voltages and may become very hot during
operation.
CAUTION
•
Note that the instrument may be damaged if the applied voltage or current exceeds
the measurement range.
•
Do not use excessive force on the touch panel, and do not use sharp objects that
could damage the touch screen.
• Do not apply heavy downward pressure with the stand extended. The stand could be
damaged.
•
If the instrument exhibits abnormal operation or display during use, review the infor
-
mation in “11.2 Troubleshooting” (p. 223) and “11.3 Error Massage and Error Dis
play” (p. 230) before contacting your dealer or Hioki representative.
•
To avoid damage to the instrument, protect it from physical shock when transporting
and handling. Be especially careful to avoid physical shock from dropping.
•
After use, always turn OFF the power.
Before Turning Power On
WARNING
•
Before turning the instrument on, make sure the supply voltage matches that
indicated on its power connector. Connection to an improper supply voltage
may damage the instrument and present an electrical hazard.
•
To avoid electrical accidents and to maintain the safety specifications of this
instrument, connect the power cord provided only to a 3-contact (two-conductor
+ ground) outlet.
•
Be sure to ground the power cord. Failure to do so will cause the enclosure to
have a voltage equal to half the supply voltage, resulting in electric shock.
•
To avoid shock and short circuits, turn off all power before connecting probes or cords.
CAUTION
Do not connect the supply voltage improperly. Doing so may destroy the instrument’s
internal circuitry.
DC resistance measurement only
To suppress noise, the instrument needs to be set to match the frequency of the power source. Before
operating, set the instrument to the frequency of your commercial power. If the supply frequency is not set
properly, measurements will be unstable.
See “Line frequency (DC)” (p. 54).
