Open.Description
Reports parameters relating to the logger's power sources as follows:
- source is one of the following names:
- usb the logger is drawing power from the USB connection.
- int the logger is drawing power from its Internal battery.
- ext the logger is drawing power from an External power source.
- int is for reporting the measured voltage of the logger's Internal battery.
- ext is for reporting the measured voltage of any External power source attached.
- capacity is the nominal power capacity of the Internal battery in Watt-hours (Wh), reported as a floating point number with three decimal places, for example: 24.000. The units are not reported.
- powersupply is a compact description of the logger's configured options for power.
The powersupply parameter reports the nominal voltage rating (not the actual measured voltage) for each of the internal battery and, if available and used, the external source:
- 12i12e: nominal 12V internal battery, external source must be compatible with a nominal 12V.
- 12i24e: nominal 12V internal battery, external source must be compatible with a nominal 24V.
- 24i12e: nominal 24V internal battery, external source must be compatible with a nominal 12V.
- 24i24e: nominal 24V internal battery, external source must be compatible with a nominal 24V.
The recommended minimum and maximum values for external supplies are:
- 12V: 9V to 15V
- 24V: 18V to 28V
Exceeding the maximum values may result in damage to the logger and/or any external sensors attached. Failing to meet the minimum may result in unpredictable behaviour and/or inaccurate data.
Examples
>> powerstatus
<< powerstatus source = usb, int = 12.40, ext = 0.00, capacity = 24.000
>> powerstatus int
<< powerstatus int = 12.39
