activity. IF problem persists, disconnect the port and connect it again. Normal behavior is when
the meter updates every 20 seconds.
NOTE: Errors could occur in the telecommunication port if the connection is not properly
secured. Also, too long of a cable may cause some inconsistencies.
Battery Level Flashing
Each strip equals to 20% of battery capacity. The bar that is flashing indicates that the battery is
within the next increment of 20% of the battery capacity. For example: when the first bar is
flashing, the battery is at 1-19% of capacity. Similarly, when the second bar of the battery is
flashing, then the capacity is at 21-39%.
NOTE: The meter measures battery capacity by the voltage it is experiencing. When
batteries are charging, they will not necessarily match the accurate battery capacity.
Battery capacity AH
AH is the accumulation of charging, each one minute will count. The data is not accurate while
the charge current is too small. The min. is 1AH, means 1 amps charging for 1 hour, Ah comes
to show.
