Startup time
Generally, there is no need to power off RBR instruments. The RBRcentauro³ will go to sleep after inactivity, consume virtually no power while on standby, and then wake up instantly when required.
If you turn off the instrument, there will be a delay starting up. Furthermore, you will have to wait for at least two minutes before turning it back on.
-
Elapsed startup time from fully discharged state to functional command interpreter: 4s maximum
-
Elapsed power downtime to complete discharge: 120s minimum
|
Ensure that the instrument is fully discharged before resuming the measurements. Power-cycling the unit for less than 120s may leave the board in an unknown state. In addition, the realtime clock may not be maintained over a power cycle. |
External port
The RBRcentauro³ uses an external MCBH-6-MP connector. It can be used for connecting to an RS-232 underwater extension cable.
