internal
Usage
>> instrument power internal [ voltage | batterytype | capacity | used ]
Security
Unsafe - parameters can not be changed if the instrument state is enabled.
Description
Allows various parameters associated with the internal battery to be reported or set.
voltage is a read-only parameter giving a live measurement of the voltage detected by the logger at the internal battery terminals.
batterytype [=<batterytype>], has a value corresponding to a chemical description of the various battery types supported; see the list below. The special name none indicates that no battery considered to be internal to the logger is present, and it will run exclusively from an external power source.
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 batteries actually in use.
Currently supported battery types are:
lisocl2 (Li-SOCl₂)
lifes2 (Li-FeS₂)
znmno2 (Zn-MnO₂)
linimnco (Li-NiMnCo)
nimh (NiMH)
other
none
capacity is a read-only parameter which reports the total nominal energy capacity (in Joules) of the internal battery selected. It can not be changed directly, but changes according to the 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 internal battery since the value was last reset. The value continues to be updated even if it exceeds the nominal capacity. When fresh batteries are installed the value can be reset to zero; this is the only accepted value for updating the parameter.
Examples
>> instrument power internal
<< instrument power internal voltage=6.52 batterytype=nimh capacity=138.000e+003 used=100.100e+003
>> instrument power internal used=0
<< instrument power internal used=0.000e+000
>> instrument power internal batterytype=lifes2
<< instrument power internal batterytype=lifes2
