5. Operating Instructions

5.1 Battery Power and Voltage Display

The meter provides clear indications of battery status.

10-bars Battery Percentage Display: Shows remaining battery power as a percentage and with a 10-segment bar graph. A low battery reminder (e.g., "Lo 10%") activates when power falls below 10%, prompting a charge.
Measurable Battery Voltage: Displays the real-time voltage of the battery. The measurement range is DC 8V to 65V.

Display examples of battery percentage, low battery reminder, and real-time voltage on the Runleader RL-BI609B battery meter. — Figure 5.1: Battery power and voltage display. This image shows the meter displaying 100% battery, a 'Lo 10%' low battery reminder, and a real-time voltage reading of 12.30V.

5.2 Programmable Backlight

The meter's white backlight can be configured to suit user preferences.

Backlight Modes: Options include "b-On" (always on), "b-OFF" (always off), and "b-Aut" (sleeping/auto mode).
