Operation Instruction
Attention: >LIMIT4000Ω displayed on LCD warns that the auxiliary earth resistance of the auxiliary
earth rods is so high that the current can not flow across the meter. Check if the test leads become
loose and the amount of the earth resistance of the auxiliary earth rods. In a measurement, test
leads twisted together or becoming contacted each other will cause error in the measurement;
therefore, make sure that a measurement is done when the test leads are separate. Besides, too
much auxiliary earth resistance will bring unacceptable error to the measurement, therefore,
respectively bury deep auxiliary earth rods such as P and C in too wet sites and ensure good
connection in each joint.
