Prepare the instrument
Before each deployment, the following three preparation steps should be completed:
- Function test: Perform a function test to verify that the instrument sensors are operating correctly. For more information, see Function test
- Pressure offset: Adjust the instrument's pressure offset to match the local atmospheric pressure before each deployment. This ensures accurate pressure measurements. For more information, see Pressure offset
-
Compass calibration: Perform a compass calibration before each deployment to ensure accurate heading and directional measurements. Skipping this step can significantly reduce velocity accuracy.
Before starting the calibration, assemble the instrument in its final deployment configuration (including the frame, shackles, chains, and any other accessories) and install the batteries, if used. For more information, see Compass calibration
💡 NOTE: While working in the software, we recommend to study the Help section during each step. There, you can find descriptions for each section and parameter selectable as well as useful tips and tricks.
Start the instrument
After testing and calibrating the instrument, upload the deployment configuration to the instrument and start the deployment. The software will indicate when the instrument has started collecting data.
Once the deployment has started, you can close the software and disconnect the instrument from the computer. Ensure that the instrument is powered, either by internal or external batteries. Even though the instrument is left unpowered for a short period between disconnecting it from the computer and applying batteries, the instrument will wake up and proceed with data acquisition according to the configuration once batteries are connected.
💡 NOTE: Depending on the deployment configuration, it may take several minutes before the instrument begins sampling. The blue LED indicates that sampling has started and flashes at the configured sampling interval.
Batteries
The Generation 2 Vector can be operated either by keeping the instrument connected to a stationary power or supply with an external battery canister. Various compatible battery options are available from Nortek. Please find below a guide on how to open and install the default 76 Wh lithium-Ion rechargeable battery.
