The position of exposed metal can be detected visually by pressing the “REVERSE” button. Bubbles of gas come out on the exposed points.
Measuring principle
Theinstrument applies aconstant micro-voltageacross thecan body andan electrode immersed intheelectrolyticwater filled, andmeasuringthe resulting current.Voltageduring the testis 6.3VDC.Theoperating rangeis 0 to300 milliamperewith an accuracy ofresolution of 0.01milliampere.
Thecover supportcomprises acontainer mountedon a pivot.The cup isbeveled tomake a tight sealon the can cover. An electrode andthe connectionto the vacuumin the containerare mounted. On the base,a valvefor creating a vacuumand a movable arm, complete the electrical circuit whenthe assembly isinverted.
Measuring modes:
- 4 second mode: The reading will be displayed only at 4 seconds.
- Continuous mode: The changing current reading will be displayed during all the measuring time. It will not stop displaying until operator’s order.
- User-defined mode: The reading will be displayed at the setting time by operator.
