error. need to check the cause and reboot (Figure 3).

not appear "OL Ω",but shows a large
resistance (Figure 4).
However, when measured with the
test ring, still gives the correct result, indicating Clamp measured
only in the high-value (for example, more than 100Ω) has large
errors, When measuring a small resistance retains the original
Accuracy, the user can rest assured use.
