Precise Measurement for Earth Resistance
(Precise Measurement Method, Three-pole Method)
CAUTION
• To prevent cable damage, do not step on cables or
pinch them between other objects. Do not bend or pull
on cables at their base.
• The ends of the auxiliary earthing rod are sharp. Be
careful to avoid injury.
• To ensure safe operation, use only the accessory
cables.
• The cable is hardened under the 0 degree or colder
environment. Do not bend or pull it to avoid tearing its
shield or cutting cable.
• If the cable melts, the metal part may be exposed
and can pose a hazard. Do not touch the area that is
generating heat.
