3. Fouling changes the cell geometry resulting in a shift in cell constant Accordingly the most important determinant of long term sensor accuracy is the cleanliness of the cell We recommend that the conductivity sensors be calibrated before and after deployment but particularly when the cell has been exposed to contamination by oil slicks or biological material Temperature Sensor Calibration The primary source of temperature sensor calibration drift is the aging of the thermistor element Sensor drift will usually be a few thousandths of a degree during the first year and less in subsequent intervals Sensor drift is not substantially dependent upon the environmental conditions of use and unlike platinum or copper elements the thermistor is insensitive to shock 40 Section 7 Troubleshootin Section 7 Troubleshooting Note See the PN 90402 SBE 45 Power Navigation and Remote Temperature Interface Box manual for additional troubleshooting steps when interfacing with the Box This section reviews common problems in operating the MicroTSG and provides the most common causes and solutions Problem 1 Unable to Communicate with MicroTSG The S gt prompt indicates that communications between the MicroTSG and computer have been established Before proceeding with troubleshooting attempt to establish communications again by clicking Connect on SEATERM s toolbar or hitting the Enter key several ti
