Usage Notes

Handling the cords and current sensors
If the insulation on a cord melts, the metal conductor may be exposed. Do not
use any cord whose metal conductor is exposed. Doing so could result in an
electric shock, burn, or other hazards.
To prevent an electric shock, do not exceed the every rating shown on either the
instrument or the options for voltage measurement, whichever is worse.
• The cable is hardened in freezing temperatures. Do not bend or pull it to avoid tearing
its shield or cutting cable.
• To prevent damage to the instrument and current sensor, never connect or discon-
nect a sensor while the instrument's power is on.
• To avoid damaging the power cord, grasp the plug, not the cord, when unplugging it
from the power outlet.
• To avoid breaking the cables, do not bend or pull them.
• For safety reasons, when taking measurements, only use the L1000 Voltage Cord.
• Avoid stepping on or pinching cables, which could damage the cable insulation.
• To prevent damage to the BNC connector, be sure to release the locking mechanism,
grip the head of the connector (not the cord), and pull it out.
• To avoid damaging the cables, unplug it by grasping the connector, not the cable.
• When disconnecting the current sensor from the instrument, be sure to grip the part
of the connector with the arrows and pull it straight out. Gripping the connector else-
where or pulling with excessive force may damage the connector.
• Avoid dropping or jarring the clamps, which could damage the jaw, adversely affect-
ing measurement.
• Do not place any foreign object between the jaws or insert any foreign object into the
gap of the sensor head. Doing so may worsen the performance of the sensor or the
opening-closing operation of the sensor head.
• Keep the clamp closed when not in use, to avoid accumulating dust or dirt on the fac-
ing core surfaces, which could interfere with clamp performance.
Use only the Hioki specified voltage cords and input cables. Using a non-specified cable may
result in incorrect measurements due to poor connection or other reasons.
