Operating Precautions
8
• Use only the specified cords and leads. Using a non-specified cord or lead
may result in incorrect measurements due to poor connection or other rea-
sons.
• If the part of the temperature sensor that connects to the instrument
becomes dirty, wipe it clean. The presence of dirt may affect temperature
measured values by increasing the contact resistance.
• Exercise care so that the temperature sensor connector does not become
disconnected. (If the sensor is disconnected, it will not be possible to per-
form temperature correction.)
CD-R disc precautions
• Exercise care to keep the recorded side of discs free of dirt and scratches.
When writing text on a disc’s label, use a pen or marker with a soft tip.
• Keep discs inside a protective case and do not expose to direct sunlight,
high temperature, or high humidity.
• Hioki is not liable for any issues your computer system experiences in the
course of using this disc.
Before Connecting the Power Cord
• To avoid electrical accidents and to maintain the safety specifications
of this instrument, connect the power cord provided only to a 3-con-
tact (two-conductor + ground) outlet.
• Use only the designated power cord with this instrument. Use of other
power cords may cause fire.
• Before using the instrument, make sure that the insulation on the
power cord is undamaged and that no bare conductors are improperly
exposed. Any damage could cause electric shock, so contact your
authorized Hioki distributor or reseller.
To avoid damaging the power cord, grasp the plug, not the cord, when
unplugging it from the power outlet.
Before Connecting Measurement Leads
To avoid shock and short circuits, turn off all power before connecting
measurement leads.
