Portable Power Module for Güralp Certimus
Monitoring
Using Discovery, open the “
Live View > GDI
” window. Provided that the Certimus
was connected to the PPM when it booted, the Channel List will include an entry for
“
Battery
”. Tick the corresponding check-boxes to select any of the six available
channels of data from the PPM for streaming and/or display.
The available channels are:
•
BattCharge
: Battery coulomb count which at power-on is initialised to a
value approximated from the battery voltage measured. This will effectively
count charge in and out of the battery to give an approximate running state of
charge of the battery. Subsequent to power-on, the value gets re-initialised
whenever the battery becomes fully charged.
•
BattChargeI
: The current flowing into the Charge Input. Always positive.
•
BattChargeV
: The voltage measured at the Charge Input.
•
BattCurrent
: The current flowing into the battery. This is positive when the
battery is being charged and negative otherwise.
Note:
Note that this may be negative even when power is being
extracted from the solar panel(s). This will happen when the
instrument is drawing more power than the panel(s) can supply.
•
BattTemp
: Temperature of the control device in the PPM.
•
BattVoltage
: Battery Voltage.
