Battery voltage can be viewed on the Status Bar located at the bottom of all screens. A fully charged battery
will display over 8 volts. The battery voltage will decrease as the SDG 200 is used. A low battery icon will be
displayed at approximately 6.5 volts.
The gauge will continue to operate until the battery can not supply enough voltage to complete a measurement.
Once this happens, the gauge will automatically shut down and will not restart until charged. Depending on the
condition of the batteries, once the voltage drops below 6 volts, the gauge may be able to take about 12 to 15
additional readings. It is important to re-charge the battery after each use.
