Simplified Measurement for Earth Resistance
(Simplified Measurement Method, 2-pole Method)
3.5 Simplified Measurement for Earth
Resistance
(Simplified Measurement Method,
2-pole Method)
DANGER
• Use the neutral side (ground side) of the commercial
power supply for this measurement. Prior to
connection, use a voltage detector etc. to make sure
that it is going to be connected with the neutral side
and take caution for electric shock.
• The instrument can be connected to the neutral
side of an outlet with a voltage-to-ground of 300 V
or less, or to the wire on the neutral side of the
breaker's secondary side with a voltage-to-ground
of 150 V or less. Do not connect with anything other
than those specified above. It can be hazardous.
WARNING
• Use the optional L9787 Test Lead for simplified
measurement for safety. Connecting the
Measurement Cables L9841, L9842-11, L9842-22,
L9843-51 and L9843-52 to a commercial power
supply may cause electric shock.
• The instrument can output a voltage of approx. 30 V.
Although the instrument has a dustproof, jet-proof
and waterproof structure, the instrument should
always be dried before using it for measurement so
as to avoid electric shock.
