Usage

>> instrument power external [voltage | batterytype | capacity | used ]

Security

Unsafe - parameters can not be changed if the instrument state is enabled.

Description

Allows various parameters associated with the external power supply to be reported or set.

• voltage is a read-only parameter giving a live measurement of the voltage detected by the logger at its external supply input connection.

• batterytype [=<batterytype>], has a value corresponding to a description of the various battery types supported; see the list below. The RBRfermata, RBRfermette and RBRfermette³ battery packs are provided by RBR Ltd; for any other type of external power source, other should be used.

  The batterytype can not be changed while a deployment is in progress. If proper estimates are required for battery capacity used and deployment life available, it is very important that the selected batterytype value matches the power source actually in use.

  Currently supported battery types are:

  • fermata_lisocl2 (Li-SOCl₂-equipped RBRfermata)

  • fermata_znmno2 (Zn-MnO₂-equipped RBRfermata)

  • fermette_limno2 (Li-MnO₂-equipped RBRfermette)

  • fermette3_lisocl2 (Li-SOCl₂-equipped RBRfermette³)

  • fermette3_lifes2 (Li-FeS₂-equipped RBRfermette³)

  • fermette3_znmno2 (Zn-MnO₂-equipped RBRfermette³)

  • fermette3_linimnco (Li-NiMnCo-equipped RBRfermette³)

  • fermette3_nimh (NiMH-equipped RBRfermette³)

  • fermata_nimh (NiMH-equipped RBRfermata)

  • other

  • none

• capacity is a read-only parameter which reports the total nominal energy capacity (in Joules) of the external battery pack. It can not be changed directly, but changes according to the selected batterytype. The capacity value for the power source types other and none is currently zero, but energy used from these sources can still be tracked.

• used [=0] reports the accumulated energy used from the external power source since the value was last reset. The value continues to be updated even if it exceeds the nominal capacity. If a fresh battery pack is installed the value can be reset to zero; this is the only accepted value for updating the parameter.

>> instrument power external
<< instrument power external voltage=14.21 batterytype=fermata_lisocl2 capacity=22.000e+006 used=100.100e+003

>> instrument power external used=0
<< instrument power external used=0.000e+000

>> instrument power external batterytype=fermata_lisocl2
<< instrument power external batterytype=fermata_lisocl2
