5. Calibration 5.1 General As with any subsea measurement device, it is important to calibrate the ROV-II probe to ensure that the reference electrodes are working properly and that there is no damage to the probe. If the probe is not calibrated, readings may be incorrect and the dive may have to be repeated. -

Pin socket 3: Reference electrode #2 (R2) 5.4 Subsea calibration The cell-to-cell value can be checked at any time while the ROV-II probe is deployed subsea. Subsea calibration should be performed with the entire cable immersed, as it will quickly detect any cable damage. -

• There is damage to the tail assembly cable or umbilical cable. When recovering the ROV-II Probe from the dive, any cable damage can be quickly located and repaired. Monitor the cell-to-cell value as the cable comes out of the water. If the problem is cable damage, the cell-to-cell value will revert to the acceptable range (10 mV or less) as soon as the damaged area of cable clears the water. -
