8-6. Current index (Current measurement)
Each time a Depth calculation is taken, a Current Index simultaneously appears on the display.

ERR : The line is disconnected.
Or, the current does not travel after the joint of the gas line / water line due to
non-conductivity.
The Current value is not affected by the depth

The current value is not affected by the depth,
but it is affected by the detection methods, the
frequencies and power level.
