Battery Hi/Lo Adj Voltage Alarm
Cuter 'n snot and it isn't some Dyson Vacuum Cleaner design quirk. http://www.ebay.com/itm/NEW-DC-VOLTAGE-MONITOR-MCKAIG-7130DC-7130DC-3-FOR-BATTERY-AND-CHARGER-WITH-ALARM-/141541555543?hash=item20...

The Volt Minder I have had for years. The issue I have with my Volt Minder, is when I engage the alarm circuit (low voltage only available) the reading on the meter drops .19 volts. I -could- compensate but when the alarm shuts off the reading jumps back up the .19 volts. This is not impressive to me. But the unit's accuracy sans engaged (engaged, not alarming) meaning just as a gauge, is 3.5 digits quite accurate. There is no way in hades that .038 milliamps is going to volt drop a 20 gauge wire -that- much.
