Measurement Precautions and Tips
How to pull out the auxiliary earthing rod
• Hold the loop part of the auxiliary
earthing rod and pull it out while
turning it.
• If it does not come out by hand, put
a hard metal bar etc. (other than the
auxiliary earthing rod) through the
loop part of the auxiliary earthing rod
and pull the auxiliary earthing rod
while turning it.
Pulling the auxiliary earthing rod with
another auxiliary earthing rod putting
through the loop causes it to be bent.
• Do not subject the auxiliary earthing
rod to radial force. Doing so may
cause it to be bent.
