Page 11: Performance
Linear sensor performance allows easy calibration. Conductivity (miniCTD) Construction Materials: The materials used in the Valeport Conductivity sensor have been specially chosen to resist compression at high pressure, This unique approach ensures that it performs within specification under even the harshest of field conditions. -
Page 12: Data Requests And Output Formats
4. Data Requests and Output Formats The “mini” range of products described in this manual is designed to be used with Valeport’s DataLog software. However, the instruments respond to a series of text commands that are detailed here, for those users who wish to interface the products to other systems. -

Page 16: Deployment
If the MiniCTD is to be deployed without the cage, the conductivity readings will be affected. To compensate for this an adjustment will have to be made to the calibration parameters. Contact Valeport for further details. 5.1. Cage The deployment cage is a rugged deployment method, providing physical protection to the instrument. -
Page 17: Clamp
Whichever deployment system is used, it is important to note that if the data is being monitored in real time via a Valeport signal cable, the SubConn connector system is not designed to be weight bearing. Suspend the instrument either from the dedicated eye in the cable, or from a separate strain wire. Do not allow the weight of the instrument to be taken through the connector itself. -
Page 18: Battery Life
87 days Note that all battery calculation figures are estimated, and may vary according to deployment temperature and the inherent battery variability. Valeport accepts no liability for the failure of a battery to last for the expected lifetime. Page 18... -
Page 19: Changing Batteries
· Replace the logger pack, rotating slowly until the location pins align. Push the logger pack home. · Replace the Acetal lock ring – hand tight is sufficient. Note that for planned periods of extended storage, the battery should be removed from the instrument to prevent accidental leakage. Page 19 © 2019 Valeport Ltd... -
Page 20: Optional Bluetooth Logger
SubConn switch cap is used on the standard logger pack. Every time the switch is removed, the instrument will start a new file. Using a standard C-cell battery, the MiniSVP/CTD fitted with a Bluetooth logger should have an endurance of ~12 hours continuous operation. Page 20 © 2019 Valeport Ltd... -
Page 21: Usb Bluetooth Receiver
DataLog software, the Bluetooth option should be checked. For use with hyperterminal, the connection is 57600 baud, 8 N 1. For use with DataLog, select the Bluetooth Comms option which fixes the baud rate to 57600 baud, 8 N 1. Page 21 © 2019 Valeport Ltd... -
