PC Interface View Built In Display Screen
Battery: 13.12 Battery = 13.12 Volts
This screen displays the current voltage on the XL™'s +12V input.
OPERATIONAL NOTE:
The display draws more than 250mA which will pull extra current from the battery and may
cause the reading to be slightly lower than if the battery is measured with a meter while the
display is turned off.

Batt Max: 13.78 Batt M ax = 13.78 Volts
Each time the XL™ measures the battery voltage it checks to see if the current voltage is less
than the minimum value detected or greater than the maximum value detected and updates the
min and max values if needed. Note that the battery voltage is not continuously monitored but is
normally only measured once each scan. The battery voltage may briefly rise higher than the
detected max value or drop lower than the min value and still not be detected.
This value is mainly provided as a diagnostic tool to help understand system performance and
reliability. A high value may indicate a faulty regulator. See ‘Reset Status Screens?’ below for
more information.

Batt Min: 12.34 Batt M in = 12.34 Volts
Each time the XL™ measures the battery voltage it checks to see if the current voltage is less
than the minimum value detected or greater than the maximum value detected and updates the
min and max values if needed. Note that the battery voltage is not continuously monitored but is
normally only measured once each scan. The battery voltage may briefly rise higher than the
detected max value or drop lower than the min value and still not be detected.
This value is mainly provided as a diagnostic tool to help understand system performance and
reliability. If the minimum voltage is too low it may indicate that the battery is being
undercharged. See ‘Reset Status Screens?’ below for more information.
