Shipping precautions
Handling the Instrument
To avoid electric shock, do not open the instrument's case. The internal compo-
nents of the instrument carry high voltages and may become very hot during
operation.
• If the instrument exhibits abnormal operation or display during use, review the infor-
mation in "14.2 Trouble Shooting" (p.216) and "14.3 Error Indication" (p.218) 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.
• The protection rating for the enclosure of this device (based on EN60529) is *IP30.
This instrument may cause interference if used in residential areas. Such use must be
avoided unless the user takes special measures to reduce electromagnetic emissions
to prevent interference to the reception of radio and television broadcasts.
Handling the cords and clamp sensors
• To prevent damage to the instrument and clamp sensors, never connect or discon-
nect a sensor while the clamp sensor is clamped around a conductor.
• 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.
• Keep the cables well away from heat sources, as bare conductors could be exposed
if the insulation melts.
• When disconnecting the BNC connector, be sure to release the lock before pulling off
the connector. Forcibly pulling the connector without releasing the lock, or pulling on
the cable, can damage the connector.
• To avoid damaging the output cable, grasp the connector, not the cable, when
unplugging the cable.
• When disconnecting the clamp 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.
