LED Behaviour
Your RBRsolo/duet has a red LED located next to the USB connector. The LED will flash in
various patterns depending on the state of the instrument, as follows:
Action
Connect download cable
Disconnect download cable from programmed
logger (either logging or pending)
Click Enable button and confirm memory erase
Installing desiccant
The RBRsolo/duet has a dedicated location for placement of desiccant in the sensor carriage,
which will accommodate one (1) Dricap desiccant capsule (part # 02-01207AG35).
Insert a fresh desiccant capsule into the desiccant holder, ensuring that it is securely placed.
To remove the desiccant, there is a small keyhole opening in the back of the carriage. Simply
use your finger or a blunt instrument to push the desiccant from the holder (Fig. 3).
Deployment
Once you have ensured that the batteries are fresh, inspected the O-rings and programmed the
logger, the instrument is ready to be deployed. There are three precautions you should take
to avoid damaging the logger:
1. Heed the maximum pressure rating of 1700m. This is indicated by the label which is
placed on the logger's sensor end cap.
2. Avoid physical stress to the logger. Any type of clamp or bracket which concentrates the
stress to the logger body is not recommended for use in logger mooring, mounting, and/or
other deployment. Stress due to improper mounting may cause the logger to leak,
resulting in the loss of valuable data or permanent damage to the electronics. RBR can
provide proper mooring and mounting clamps suited to your specific application.
3. Use desiccant. If the logger is closed up in a warmer environment than the deployment
environment, internal condensation can result. Since condensation may cause the
circuitry to malfunction, the installation of fresh desiccant prior to deployment is
mandatory.
4. Orientation on a mooring. Due to battery capacity potentially being sensitive to cell
orientation, it is best to mount the logger with the sensor end facing down when
deployed. Even if batteries that are minimally sensitive to cell orientation are used (e.g.
Tadiran), it is always good practice to mount the loggers in this manner in the event that
any brand of battery is employed.
