Recommended Troubleshooting Tools

Digital Multi-meter

A multi-meter is definitely a must-have tool when troubleshooting an electronic device, such

as an alarm panel.

An inexpensive, basic digital multi-meter that can measure AC voltage, DC voltage, Ohms

( Ω ) and continuity is really all you need for basic troubleshooting.

Analog multi-meters (like the applause-meter on old TV game shows) will work, too, but

may be difficult to read.

Also, always try to keep a spare battery for your multi-meter. When your meter's battery is

low, the meter may not give an accurate reading.
