CAVIDERM CD-8 principle:
CD-8The operation is based on4Principle of point resistance testing.
DCThe pulse of current is transmitted to the conical probe, and then these pulses are uniformly transmitted to the hole to be tested. The voltage on the probe contactor is directly transmitted through the copper column in the test hole, and then fed back to the instrument for calculating resistance to convert it into thickness and display it.
