For me the best time to test is right after dusk. Review: Inexpensive and effective - Inexpensive and effective electric fence tester.

Works as expected. ## Features - Widely Application: The electric fence tester can only be used to test standard duty, low impedance electric fences. You can use it checking power on the electric fence around the garden, small enough to carry in a pocket.

Hook the metal loop on top to the wire, stick the probe in the earth. Just hang it on the fence and stick the probe in the ground under the fence.

It uses neon bulbs, not LEDs to show voltage, neons are durable and can handle thousands of volts, much easier to read in shade or in evening light. - Dim Lights And Neon Principle: The electric fence testers have a pulse low voltage wire fence, make sure the wires are not touching anything metal by using plastic insulation to attach wires to your fence posts. The tester does not use batteries, and thus works on the principle of the fence high voltage exciting a neon bulb. As such, the light will never be bright, due to the technology of the bulbs.
