First deployment

RBR ships the RBRsolo⁴ ODO and the RBRduet⁴ D.ODO instruments with a hydrated storage cap on, so that the instrument is ready for its first deployment. However, long transportation times and low cabin pressure may cause the water to evaporate. Verify that the storage cap is still wet. If not, rehydrate the sensor for five days before deployment.

Calibration

Check your sensor calibration before each deployment in saturated fresh water. If the readings are not within 1% of 100% saturation, recalibrate the instrument using a one-point calibration. Typically, | fast instruments may need recalibration more often than standard or | slow. See Ruskin User Guide: Compact Instruments⁴ for user calibration instructions.
