● If measurement is made with the test leads twisted or in touch with each
other, the reading of the instrument may be affected by induction. When
connecting the test leads, make sure that they are separated.
● If earth resistance of auxiliary earth spikes is too large, it may result in
inaccurate measurement. Make sure to stick the auxiliary earth spike
P(S) and C(H) into the moist part of the earth carefully, and ensure
sufficient connections between the respective connections.
● If auxiliary earth resistance is higher than 100 times of the upper limit
value of the selected measurement range, the measured result may be
displayed on the next higher range.
e.g.:
When the measured result is 10 Ω, the LCD normally shows "10.00Ω",
however, it may show "10Ω".
