My two multimeters ended up with a dead battery.
No spare battery in the drawer.
Winter storm outside.
Little useful contraption to test circuits when you have nothing else:
3V light up the led when the circuit is closed.
Saved my day.
BTW... the same 3V battery holder, without the Led, is very handy to briefly test LEDs polarity without need for a resitor.Jackpilot
