Step 1
Consider the type of voltage tester needed. Testers commonly test specific electrical applications. For example, an electrical fence voltage tester determines the presence of electricity through a fence.
-
Step 2
Look for low-end voltage testers that test AC/DC, usually with neon bulbs that indicate the presence of volts. Pen type AC/DC with preset voltage amounts rank high for homeowners.
-
Step 3
Examine the variety of battery testers for lithium, photocells, nickel cadmium and standard batteries. These test all kinds of batteries by using positive and negative probes with readouts in either digital or analog.
-
Step 4
Buy a non-contact voltage detector to confirm the presence of voltage without electrical contact with the tester. Choose a model with visible and or audible indicators.
-
Step 5
Purchase a plug tester designed for outlet receptacles. These either light up with the presence of voltage or remain blank with any absence. They plug in like any household appliance or device.
-
Step 6
Determine your upper price range for a voltage tester. A digital multi meter provides more testing capabilities beyond voltage. Standard models measure voltage, current and resistance. A high-end voltage tester offers digital readouts with a large voltage range and quality construction.

Step 7
Check out local electronic stores, home improvement outlets and hardware stores for hands-on experience before you buy.
